Instrument Description
This instrument is a compact and portable Spectrum Analyzer for the 9 kHz to
1.8 GHz frequency range (up to 2.15 GHz with Option 50 or Option 75
installed). Microprocessor control of most functions simplifies and enhances
operation.
The Spectrum Analyzer’s main features are:
H
Precision Measurements Menu selectable routines provide directions for
normalizing the internal reference (calibrator signal) to external frequency
and amplitude references. After the internal reference is normalized, other
menu selections provide for normalizing any instrument measurement
parameter.
H
Menu Operation Menu-selectable routines provide diagnostics, normalization, adjustments, and setup of basic parameters such as center frequency,
frequency span, reference level, vertical scale factor, resolution bandwidth,
etc. These menus are described in Section 6: Spectrum Analyzers Menus of
the 2715 Spectrum Analyzer Users Manual.

Operating Information
Instrument Construction
Modular construction provides ready access to the major circuits. Each circuit
board containing RF sensitive circuits is mounted in a casting, with feed through
connectors through the compartment walls. Most boards and assemblies plug
onto a common interconnect board. Most adjustments and test points are
accessible while the instrument is operational and without need of a circuit board
extender.
Circuit board extenders are available in an optional Service Kit (see Maintenance
section under Fixtures and Tools for Maintenance on page 6--3). Most of the
modules or boards can be removed without affecting the structural or functional
integrity of other modules. The extender board allows any of the six circuit board
assemblies in the card cage to be positioned for service or adjustment. The
Sweep and Power Supply circuit boards are accessed by removing the instrument’s cabinet (and the Variable Resolution assembly in the case of the Power
Supply).
All other circuit boards are accessible by removing the instrument’s cabinet and
the shielding associated with each assembly.
NOTE. Disassembly of some modules may require special tools and procedures.
These procedures and a list of tools are located in the Maintenance section.
Most RF circuits are isolated in shielded compartments to obtain and maintain
the frequency stability, sensitivity, and EMI characteristics. While shielding
helps ensure a spurious free response, the closeness of the circuits reduces losses
and interactions with other functions. Interconnections between compartments
are made by feed through terminals rather than cables. If the compartments are
opened, be sure that the shields are properly reinstalled before operating.
Installation and Preparation for Use
Refer to Section 2: Getting Started of the 2715 Spectrum Analyzer User Manual
for unpacking, storage, repackaging for shipment, and installation information.
Power Cord
The power cord that is supplied with the instrument depends on the available
power source (see Section 1: Specifications). Power cord options are described in
Section F: Options.

Operating Information
Replacing the Fuse
Replace the line fuse with a 2 A Slow Blow fuse.
Selected Components
Some components are specifically selected to meet Tektronix specifications.
These components are shown in the parts list.
Selected value components are identified in the parts list as a SEL value. The
component description lists either the nominal value or a range of values.
Assembly and Circuit Numbering
Each assembly and subassembly is assigned an assembly number. Generally,
each component is assigned a circuit number according to its geographic location
within an assembly. The Replaceable Electrical Parts list prefixes these circuit
numbers with the corresponding assembly and subassembly numbers.
Example: R260 on assembly A14 becomes A14R260.
Example:U140 on subassembly A1 of assembly A19 is found in the
electrical parts list as A19A1U140.
Accessories
The Replaceable Mechanical Parts section contains part numbers, descriptions,
and ordering information for all standard and optional accessories offered for this
Spectrum Analyzer.
Refer to Appendix F: Accessories & Options in the 2715 Spectrum Analyzer
User Manual for listings of standard and optional accessories.
Refer to Section 7: Options in this manual for information on accessories
associated with options.
The Accessories at the end of the Replaceable Mechanical Parts in this manual
contains information on all standard accessories currently available with this
Spectrum Analyzer.

Theory of Operation
A 25 Ω resistor within the RF INPUT connector assembly is placed in series
with the signal path. This transforms the connector to a 75 Ω impedance for
external signal connections. All RF signal connections within the 2715 (SMA
and SMB connectors) have a 50 Ω impedance. RF type signal connections
between modules are made using double shielded coaxial cables, while DC type
signal connections are made using either multipin jacks on the Power Supply
board (Power Supply, Log Amplifier, Display Storage, Microprocessor, and
Center Frequency Control boards) or small ribbon cables.
The Main Interconnect Diagram at the front of the Diagrams section provides a
chart of the interconnect system in addition to what is shown in Figure 3--1.
Block diagrams showing more detail of these main sections appear before the
appropriate schematics together with another description. Circuit schematic

Theory of Operation
What It Does
The Spectrum Analyzer accepts an electrical signal as its input and displays the
signal’s frequency components on a CRT. Signals are applied directly to the RF
INPUT.
The display of the input signal appears on the CRT as a graph where the
horizontal axis is frequency and the vertical axis is amplitude.
How It Works
Attenuator and Low Pass
Filter
The Spectrum Analyzer operates as a variable bandwidth receiver. The CRT
beam moves horizontally as a range of frequencies is scanned. When a frequency
component of an input signal is detected, the beam is deflected vertically as a
function of input power at that frequency.
There are two selections for inputs to the Spectrum Analyzer: the RF INPUT at
the front panel and the internal calibrator signal.
The Attenuator adds attenuation to the input signal such that the level at the
input of the 1st mixer (1st Converter) is limited to no more than --30 dBm. This
would represent a full screen signal. Also, an amplifier can be inserted in the
signal path to improve sensitivity when small signals are applied to the RF
INPUT by invoking the Preamp mode. The Microprocessor sets the amount of
attenuation, depending on the user selected reference level, to maintain the
proper signal level.
The signal is then routed to the 1st Converter through a Low Pass Filter. The
Low Pass Filter attenuates out-of-band signals and helps minimize 1st Local
Oscillator (LO) emission at the RF INPUT. When the Preamp mode is invoked,
the Microprocessor sets the appropriate amount of attenuation, or it sets the gain
of an internal amplifier (Variable Resolution) to maintain a calibrated display.
1st Converter and
Bandpass Filter
2nd Converter
The input signal is converted to an intermediate frequency (IF) signal of
2110 MHz. This is accomplished by mixing the input signal with an LO signal
that varies over a range of 2.11 GHz to 3.91 GHz (4.26 GHz for Option 50 and
Option 75). The LO range corresponds to a range of 0 Hz to 1.8 GHz (2.15 GHz
for Option 50 and Option 75) at the RF INPUT. The output of the mixer is then
amplified to compensate for the conversion loss, and it is filtered to allow only
the difference frequency to pass. All other mixer products are attenuated.
The 2nd Converter down converts the 2110 MHz IF signal to 110 MHz, then
routes this 2nd IF to the RF Mother board.
2715 Spectrum Analyzer Service Manual
3- 3
Theory of Operation
RF Mother Board
Assembly
The RF Mother board assembly contains a 2 GHz 2nd LO, a 2nd Converter,
several gain stages, a 5 MHz resolution bandwidth filter, and a 3rd Converter.
The 2nd Converter down converts the 2110 MHz 1st IF to 110 MHz. The 3rd
Converter down converts the 110 MHz 2nd IF to a 10 MHz 3rd IF. This signal is
routed to the Variable Resolution module.
Variable Resolution
Module
The Variable Resolution contains several selectable gain stages prior to the filters
and a compensation amplifier. One of the nine filters is selected. Each filter has
an attenuator pad associated with it to compensate for losses in the filter. The
system selects the appropriate amplification factor as each filter is selected.
The 10 MHz IF signal is processed through one of several Bandpass filters,
amplified once more, and then routed to the Log Amplifier board.
Log Amplifier
The Log Amplifier performs the logarithmic conversion, linear detection and
logarithmic detection of the incoming signal, and amplitude calibration. The log
display has scale factors of 10 dB/div, 5 dB/div, and 1 dB/div. The module also
contains an FM detector, an audio amplifier, an amplitude limited output for the
period counter, and an out-of-band signal clamp.
The detector produces a voltage that corresponds to the input signal strength in
decibels. The detector output is then vertically scaled and sent to the Display
Storage and Sweep boards.
The control processor uses three 8 bit shift registers to control the Log Amplifier.
Display Storage
The Display Storage board contains the circuitry for putting text and waveforms
onto the CRT display.
This board contains the following programmable functions:
H
Waveform Storage — four 512 point waveforms
H
Dot Markers — up to two intensified markers
H
Text Storage — four 32 character by 16 lines of text
H
Accumulator data — direct access to the output of the A to D converter
H
Nonvolatile memory — 32 Kbytes total; 2 Kbytes used for waveforms;
2 Kbytes used for text; the rest is available for general use
When enabling the analog display, waveforms A, B, C, and D are turned on, but
not displayed. This results in a chopped blanking effect between the readout and
the analog display. The scanning alternates between the readout and the analog
display.
3- 4
2715 Spectrum Analyzer Service Manual
Theory of Operation
The Display Storage board is capable of storing four waveforms of 512 bytes
each, four pages of text of 512 bytes each, and up to two markers. Any combination of waveforms and text may be displayed on the CRT. If any waveforms are
being displayed, the text portion of the display is limited to approximately 100
characters in order to avoid flicker.
Only one page of text may be displayed at any one time. The readout page is
limited to approximately 100 characters.
The waveforms and text displays are accessed through memory reads and writes.
When (DISPLAY) A, B, C, or D is selected, the stored waveforms in those
registers are displayed. When A, B, C, and D are deselected, the display reverts
to the real time (nondigitized) video waveform, and the readout is updated during
the readout cycle.
Center Frequency Control
The Center Frequency Control system provides 1st Local Oscillator (1st LO)
signal to the 1st Converter at the center frequency and span selected by the user.
In general, this is accomplished by a combination of setting, counting, and
resetting (as required) of the frequencies of various oscillators.
The system is expected to control the frequency within a few Hz out of a total
operating range of approximately 2 GHz.
The principal elements of the frequency control system are as follows:
1st LO
This is a YIG tuned oscillator that covers the range of 2.11 to 3.91 GHz or 2.11
to 4.26 GHz for Option 50 and Option 75 (YIG = Yttrium Iron Garnet.) Ideally,
its operating frequency is exactly proportional to the strength of an internal DC
magnetic field. This field is the combined field of two coils, one large (Main)
and one small (FM). In practice, the frequency is uncertain by up to a few MHz
due to problems such as temperature drift, slight nonlinearity, and magnetic
hysteresis. Also, the oscillator has some residual FM and phase noise sidebands
due to internal causes and external noise and drift from the driver circuit. The
remainder of the frequency control system maintains the oscillator (abbreviated
YIG) at the right frequency. Usually, it is sufficient to set the YIG, then
periodically check its frequency and make small adjustments as required.
However, in very narrow spans the YIG must be phase locked to a stable source
in order to maintain sufficient stability.
The 1st LO Interface provides drive signals for the main coil and FM coil, a
control signal for the main coil, and power for the gain stage.
2715 Spectrum Analyzer Service Manual
3- 5
Theory of Operation
100 MHz Reference
Oscillator
This is a precision, temperature controlled, quartz crystal oscillator that provides
the reference around which all instrument frequency related performance
revolves. It is designed for maximal frequency stability over temperature and
time, with absolute frequency accuracy being secondary. The instrument
firmware accounts for any frequency inaccuracy, producing a virtually perfect
reference.
Phase Gate
The phase gate is a high speed sampling switch that takes a very brief sample of
the 1st LO waveform once during each cycle of the strobe frequency. (The strobe
is a control signal supplied to the phase gate from an external source.) These
samples are later averaged by a low pass filter to eliminate ripple at the strobe
frequency, and also to eliminate other undesirable components.
When the 1st LO is phase locked to any integer multiple of the strobe frequency,
the resulting output is a phase dependent DC voltage that is used as the error
voltage in a feedback loop to maintain phase lock.
When the 1st LO is not phase locked, the resulting output is a beat note
occurring at the difference frequency between the 1st LO frequency and the
nearest integer multiple of the strobe frequency. (Actually, many beat frequencies
are present at once, but the low pass filter eliminates all but the one of lowest
frequency.)
Phase Lock Center
Frequency Control
(PLCFC)
Firmware
This element is the focal point of the frequency control system hardware. It
accepts commands from the instrument microprocessor and then puts out
appropriate drive signals to the 1st LO as well as a suitable strobe signal to the
Phase Gate. The PLCFC module also uses the Phase Gate output. It also
provides counter signals and status information to the microprocessor. It requires
the 100 MHz reference signal in order to function.
Because of the variety of tasks that the Spectrum Analyzer is called upon to do,
it is essential to have an intelligent controller. This is especially true in the
frequency control context, because the required degree of control could not be
economically obtained with unassisted analog hardware.
Instrument firmware has the task (among many others) of commanding the
frequency control hardware, taking feedback from it, and making readjustments
as required to obtain the desired result.
The interface between the microprocessor system and the PLCFC module is
through a pair of serial data lines, some latch lines, and some clock signals.

2715 Spectrum Analyzer Service Manual
Theory of Operation
1st LO Buffer
The 1st LO Buffer consists of a Leveled Amplifier and a Phase Gate Detector.
The Leveled Amplifier provides the LO input drive for the 1st Mixer. The Phase
Gate Detector logs 1st LO drift. That information is then used for frequency
corrections.
Sweep
The Sweep board contains a microprocessor interface, horizontal sweep
generator, trigger circuitry, vertical sweep (raster scan) circuitry, video processing, video line triggering, and graticule illumination.
This board receives messages from the microprocessor regarding its operation,
but cannot send messages directly to the microprocessor.
Various combinations of resistors and capacitors yield the sweep speed selections.
The available trigger modes are Free Run, Internal, Line, External, TV Field, and
TV Line. When the video monitor mode is selected, the readout, display storage,
and video filter are turned off. In addition, the resolution bandwidth is set to
5 MHz, the Vertical display mode defaults to Lin, the span setting defaults to
Zero Span, and the sweep rate defaults to 5 s. The video monitor mode is
turned off from the trigger menu or by selecting another trigger mode.
TV Line Trigger mode causes the Spectrum Analyzer to trigger on the selected
video line. The selected line, and part of the next line, are displayed.

The Display System consists of the Vertical Display circuit, Horizontal Display

video signals.

Circuit Description
The following sections provide detailed circuit descriptions and is arranged to
follow the input signal flow. While reading these descriptions, refer to the
corresponding diagrams in Section 9: Diagrams.

The Spectrum Analyzer input frequency range is 9 kHz to 1.8 GHz (2.15 GHz
for Option 50 and Option 75). The low end of the frequency range is determined
by a capacitor on the Attenuator board, the narrowest resolution filter in the
Variable Resolution assembly, and FM characteristics of the 1st LO (YIG
Oscillator).
The signal comes in at the front panel RF INPUT connector. The 75 Ω RF
INPUT connector is connected to a 0 to 50 dB step attenuator, capable of
stepping from 0 to 50 dB in 2 dB steps. The Attenuator consists of relay
controlled pads of 2, 4, 8, 16, and 20 dB. The instrument firmware controls the
relays to provide the necessary attenuation to maintain a calibrated reference
level.
2715 Spectrum Analyzer Service Manual
3- 9
Theory of Operation
A relay switch at the input of the Step Attenuator selects the RF input signal or
the internal calibrator signal. See Figure 3--3. Since the calibrator signal comes
into the Step Attenuator assembly ahead of the attenuators, it can be used to
verify the accuracy of the Step Attenuator and other parameters. Selection is
made through the INPUT MENU.

Also, an amplifier with 18 to 20 dB of gain may be inserted in the signal path at
the output of the Step Attenuator. This is the Preamp mode, selectable through
the INPUT MENU. It is used to enhance sensitivity, when small signals are
applied to the input, by maintaining the same signal to noise ratio from the input
to the 2nd Converter. When a small signal is applied to the RF INPUT, and the
Preamp mode is activated, both the signal and the noise level are amplified an
equal amount. Any attenuation less than the gain of the preamp will then
attenuate both the signal and the noise. Thus, signal to noise ratio remains nearly
constant. In the meantime, the instrument makes corrections in the IF to maintain
a calibrated reference level.
Low Pass Filter
3- 10
The Low Pass Filter attenuates all out-of-band frequencies. It rejects all
frequencies above 1.8 GHz (above 2.2 GHz for Option 50 and Option 75),
preventing them from reaching the mixer input and creating unwanted images. It
also reduces emissions from internally generated frequencies above 1.8 GHz
(above 2.2 GHz for Option 50 and Option 75).
2715 Spectrum Analyzer Service Manual
Theory of Operation
1st Converter
The 1st Converter converts the incoming RF signals to the 1st IF. Input signals
are applied through the Step Attenuator and Low Pass Filter and through the 1st
LO Buffer Amplifier.
The 1st Converter receives the RF signal through the Low Pass Filter and a 1st
LO signal from the 1st LO Buffer Amplifier. These signals combine to produce
mixing products that are filtered to yield the 2110 MHz IF signal.
The mixer output is coupled to the input of a balanced amplifier where the signal
is split into two paths. The signals in the two paths are 90 degrees out of phase.
The signals are recombined at the output, yielding a gain of approximately
10 dB. Any reflections to the input are dissipated in a 50 Ω termination. The
output is also terminated in 50 Ω to assure a match at the output port.
Bandpass Filter
The Bandpass Filter (a four cavity filter) is a low loss, narrow band filter that
only passes the 2110 MHz IF signal to the 2nd Converter. Any other frequencies
are reflected back to the 1st Converter and dissipated in the termination. In
addition, the filter prevents the 2nd Converter LO and mixer products from
feeding back into the 1st Converter.
Each end resonator is capacitively coupled to external circuits through a coupling
hat plugged into a 3 mm connector. Inter cavity coupling is provided by coupling
loops that protrude from the machined filter top. The resonant frequency of each
cavity is determined primarily by the depth of a gap in the underside of the filter
top and is fine tuned with a tuning screw on the side of each cavity. When
properly tuned, the filter return loss is >25 dB from either end (in a 50 Ω
system). Figure 3--4 shows the equivalent electrical circuit.

RF Mother Board and Phase Locked 2nd LO
This section contains a detailed description of the RF Mother board and Phase
Locked 2nd Local Oscillator.
Overview
RF Mother Board
Block Diagram
The RF Mother board converts the 1st IF frequency to 10 MHz in two frequency
conversions. The first conversion (2nd mixer) mixes the 2.11 GHz 1st IF with
the 2 GHz 2nd LO to create a 110 MHz second IF. The 2 GHz LO is generated
on the board and is phase locked to the 100 MHz crystal reference. The 110 MHz
2nd IF is amplified (with variable gain) and filtered by a 5 MHz bandpass filter.
A portion of the 2nd IF signal is sent to the sweep board for use by the satellite
demodulator. The 3rd conversion mixes the 2nd IF with the 100 MHz reference
to produce the 3rd IF frequency of 10 MHz. This signal is amplified and sent to
the variable resolution module.
This section provides a block diagram description of the RF Mother board as
illustrated in Figure 3--5.

The RF Mother board converts the 1st IF frequency (2.11 GHz) down to
110 MHz by mixing it with a 2 GHz LO. This LO is created by phase locking a
VCO to the 100MHz reference frequency. This reference is provided by the
Reference Oscillator module.
3- 12
2715 Spectrum Analyzer Service Manual
Theory of Operation
The 110 MHz 2nd IF is amplified and divided along two paths. One path is
through a buffer amplifier to the sweep board where the signal is available to the
satellite demodulator. The second path is through a PIN attenuator which sets the
gain of the module. The signal then passes through a second amplifier stage then
a 110 MHz Bandpass filter. This filter has a 3 dB bandwidth of 5 MHz which
sets the widest resolution bandwidth of the instrument. After the 5 MHz filter,
the signal is again amplified and applied to the 3rd converter.
The 3rd IF is created by mixing the 2nd IF with the 100 MHz reference to create
the 3rd IF frequency of 10 MHz. The mixer output is filtered to reduce the 2nd
harmonic level, and then amplified before being applied to the VR module.
Detailed Circuit
Descriptions
This section describes specific elements of the RF Mother board.
2 GHz Phase locked LO. The 2nd local oscillator is formed by Q112 and C204. In
this configuration, the VCO oscillates into a 50 Ω load. The resonator ensures
that this frequency will be close to 2 GHz. The VCO is tuned by varying the
emitter base voltage, which causes that junction to act as a varactor.
A sample of the 2 GHz signal is divided by 4 (U424) and sent to a mixer/phase
detector (U511). The mixer is driven by the 100 MHz reference, so the DC mixer
output is created by the divide-by-4 sample and the 5th harmonic of the
100 MHz reference. This signal is integrated (U444) and connected to the Q112
emitter, closing the loop.
U230A provides a clean --8 V bias to Q223. If the loop is unlocked U230B
causes the control loop to oscillate, sweeping over its full range until lock
occurs. C323 (10F) and related circuitry insures start up by pulling the control
voltage high at turn on.
2nd Mixer. This single balanced mixer is formed by CR223. The 2 GHz 2nd LO
is applied to the diodes through amplifier (Q322), and the 2.11 GHz input and
110 MHz 2nd IF are separated by a filter.
110 MHz Amplifiers. These IF amplifiers consist of common emitter transistors
(Q130, Q140, and Q150) with both series and parallel feedback. The 1:1 transformers (T130, T140, and T150) provide lower output impedance for better
intermodulation distortion performance.
PIN Attenuator. CR369 and CR367 are PIN diodes and are used to adjust the gain
of the module. PIN diodes behave like resistors at RF frequencies, with the value
being dependent on current flowing in the diode. (High current, low resistance;
low current, high resistance). Current through CR369 decreases attenuation and
current through CR367 increases attenuation. R200 adjusts the current through
the PIN diodes and has a range of approximately 15dB attenuation.

Output Amplifier. This IF amplifier consists of a common emitter transistor
(Q670) with both series and parallel feedback. The 1:1 transformer (T670)
provides lower output impedance for better intermodulation distortion performance. The resistive attenuator at the output is used to match the load to the
variable resolution. It also provides some high frequency roll off.
1st LO Interface, 1st LO, and 1st LO Buffer Amplifier
This section contains a detailed description of the 1st LO Interface, 1st LO and
1st Buffer Amplifier.
1st LO Interface
and 1st LO
The 1st LO has a tuning range of 2.11 to 3.91 GHz (2.11 to 4.26 GHz for Option
50 and 75). The oscillator assembly includes the interface circuit board that
couples operating and tuning voltages from the Center Frequency Control board.
Two Zener diodes on the Interface board clamp transient voltages from the main
coil. See Figure 3--6.

Theory of Operation
When the FM coil is used to sweep the oscillator, the relay on the Interface board
closes and couples a large capacitor (two capacitors in parallel) across the main
coil. The capacitors lower the noise bandwidth of the main coil driving circuit
while the FM coil is in operation. The heater provides temperature stability.
The rest of the circuitry on the Interface board provides operating voltages for
the two amplifiers in the 1st LO assembly.
The output of the 1st LO drives the 1st LO Buffer Amplifier.
1st LO Buffer Amplifier
The 1st LO Buffer Amplifier consists of the following:
H
Automatic Level Controlled (ALC) Amplifier
H
Strobe Driver
H
Sampling Gate
ALC Amplifier. The ALC Amplifier is composed of a wide band amplifier with
impedance matching transmission lines at the input and output, a directional
coupler, a detector, a level comparator, and active bias. See Figure 3--7.

Theory of Operation
The directional coupler couples approximately --15 dBm of the amplified LO
signal to the detector. The coupled signal is then amplitude detected, and the
resultant DC level fed to the noninverting input of a comparator, where it is
compared to a reference DC level. (The reference DC level is connected to the
inverting input.) The output of the comparator then controls the active bias
tending to hold the amplifier’s output at a constant level.
Strobe Driver. A Strobe signal from the Center Frequency Control assembly is
coupled to the Strobe Driver. The Strobe Driver is a transformer coupled gain
stage. The Strobe Driver’s output is coupled to the Sampling Gate.
Sampling Gate. A power divider at the input of the amplifier routes 50% of the
1st LO’s output to another power divider. One port of the second divider is
reserved for Option 15 and is terminated in 50 Ω. The other port is coupled to the
Sampling Gate.
If the output frequency of the 1st LO were stable, LO sampling would occur at
the same level since the rate at which the LO output is sampled is constant.
However, the LO output has a tendency to drift slightly under certain conditions,
such as unstable ambient temperature. Consequently, sampling occurs at different
levels, resulting in a beat note. Thus, the BEAT NOTE signal is a measure of the
1st LO’s drift.
The output of the Sampling Gate is routed to the Phase Lock Center Frequency
Control (PLCFC) module.
Reference Oscillator
The Reference Oscillator board provides a 100 MHz frequency reference and
amplitude reference for the Spectrum Analyzer. The frequency reference enables
the high counter accuracy.
Firmware based routines use the Amplitude Calibrator output as a reference for
calibrating internal gain settings.
The Reference Oscillator consists of the following blocks of circuitry:

Crystal Heater. The Crystal Heater maintains the oscillator crystal’s case
temperature within a 3° window of the crystal’s operating temperature (near

the AC equivalent for the oscillator. At resonance, the tank inductor and
capacitor Lt and Ct exhibit an open circuit condition, and the LC equivalent of
the crystal (Lm and Cm) exhibit a short circuit condition. Thus, at resonance, the
open loop gain is calculated as:
A =

(r e1 + r e2 + r s)
This gain must be greater than unity to ensure oscillation.

At oscillation, the loop gain is unity and the phase 0°. If the phase delay of Q1,
Q2, or the tank changes, the operating frequency must also change to maintain a 0°
loop phase shift. Because of this phase/frequency shift dependency, the Q of the
parallel tank circuit is made as low as possible to minimize the tank phase change
as the values of Lt and Ct drift.
The component values of the tank circuit are determined by the voltage swing at
the collector of Q2 (Figure 3--11). The collector of Q2 drives an ECL line receiver.
Therefore, the collector voltage should swing 1 V peak to peak about 3.8 VDC
(3.8 V being the ECL Vbb bias voltage). The gain of Q2 is calculated as:

carefully controlled current on and off across a 56.2 Ω resistor. The resulting
signal, with a --22 dBm level, is routed to the calibrator port through an 8 dB
pad.

Microprocessor Interface. The Microprocessor Interface is used by the Microprocessor board to communicate with the Reference Oscillator board. An 8 bit input
shift register controls the operation of the board, and an 8 bit output shift register
contains frequency correction bits for indicating the Oscillator frequency. The
microprocessor clocks (CLKO) eight bits of serial data (DATAO) into the input
serial register, and it then latches the serial contents (RFLATCH--) to the parallel
outputs. The microprocessor clocks data out of the output register by setting bit 7
of the input register low to enable the Buffer (see Figure 3--8 on page 3--17) and
using CLKI-- to clock serial DATAI out. Refer to Table 3--1 for the bit mapping
of the registers.
Bit 0 of the input register is the last bit to leave the microprocessor, and bit 0 of
the output register is the last bit to reach the microprocessor.
Bit 0 of the input register enables the calibrator signal when high and disables it
when low. Bit 7 of the input register allows the microprocessor to read the
contents of the output register when set low, and it tristates the output buffer
when set high.

The output register has 8 bits available to represent the Oscillator frequency. The
microprocessor can then read the Oscillator frequency through these bits to
within 10 Hz. The possible values are 1 through 254. The microprocessor
interprets a value of 128 as a frequency of 100 MHz, 127 as 99,999,990 Hz, 129
as 100,000,010 Hz, and so forth.
Values 0 (all bits low) and 255 (all bits high) are used to send a hardware failure
message to the microprocessor.
Phase Lock Assembly (Center Frequency Control System)
There are three major operating areas of the frequency control system:
2715 Spectrum Analyzer Service Manual
3- 21
Theory of Operation
In wide spans (5.1 MHz/div or greater), the center frequency is set coarsely by
setting a suitable bias current in the main coil. Fine increments of the center
frequency are set by appropriate currents to the FM coil. In this mode, sweeping
over the span is accomplished by summing a suitably scaled analog sweep signal
with the drive to the main coil. The strobe signal is not even turned on except
briefly when needed to assist in verifying the exact 1st LO frequency by
counting the beat frequency.
In moderate spans (50 kHz/div through 5 MHz/div), sweeping is done by
summing the scaled sweep signal with the drive to the FM coil. Additionally, a
noise suppressing low pass filter is inserted into the main coil circuit to reduce
residual FM and phase noise due to noise from the main coil driver. Otherwise,
the setup is the same as for wide spans. In this mode, the strobe is unused except
when counting the 1st LO frequency.
When operating in narrow spans (20 kHz/div and less), the 1st LO is phase
locked to a harmonic of the strobe frequency. Coarse control of the center
frequency is effected by choosing which harmonic of the strobe frequency is
used (by setting an appropriate main coil current before commanding the
hardware to lock). Sweeping and fine control of center frequency are done by
controlling the strobe frequency. When phase locked, the FM coil is used by the
loop to adjust the 1st LO to zero phase error.
PLCFC Module Functional Blocks. The Phase Lock Center Frequency Control

There are six regulated supplies on the PLCFC circuit board and two additional
regulators in the VCO module.
- 5 V Reference Supply (- 5 VREF). This is a precision reference supply for those
circuit applications where a critical frequency is directly dependent on a voltage
or current.
3- 22
2715 Spectrum Analyzer Service Manual
Theory of Operation
This supply consists of VR160, U166, U174, Q170, Q674, and associated
components. VR160 is a temperature compensated reference diode that defines
the output voltage. U166 and Q170 constitute a buffered scaling amplifier to
provide the desired --5 V output at sufficient current. C660 makes the closed loop
bandwidth very low to minimize noise from the reference diode on the output.
U174 and Q674 convert --5 V to +10 V to provide stable low noise current to the
reference diode through R171. The +8.5 V path through CR175 is used to
guarantee start up of the supply. CR175 disconnects the potentially noisy start up
source once the emitter of Q674 goes sufficiently positive.
- 5 V Supply. This supply is not to be confused with the --5 V Reference Supply.
This supply is regulated by U470 and serves solely as a reference for the
remaining four supplies on the board. U470 is a programmable shunt regulator
whose output voltage is defined by an internal reference and by R472 and R473.
+8.5 V Supply. U282A and Q781 constitute a buffered operational amplifier used
in the inverting configuration to provide +8.5 V from an input of --5 V. (Note that
Q781 provides a phase inversion, so the polarities of the operational amplifier IC
input pins have to be reversed from the usual practice.)
+15 V Supply. U380B and Q880 operate in the same fashion as the corresponding
parts in the +8.5 V regulator.
- 8.5 V Supply. U282B and Q780 serve as a buffered operational amplifier in the
non inverting configuration to provide --8.5 V.
+5 V Supply. U380A and Q881 serve as a buffered operational amplifier used in
an inverting configuration to provide +5 V. (Note that Q881 is used in noninverting fashion, so that the normal polarities of the operational amplifier IC
terminals apply here.)
The regulators in the VCO module will be discussed later in this section on
page 3--25.
1st LO Coil Drivers
Current Source
It is desirable to drive the 1st LO coils from high impedance sources so that
temperature dependent changes in winding resistance have negligible effect on
stability.
Main Coil Driver. U921 and Q521 constitute a buffered operational amplifier used
in an inverting configuration. Inputs to the summing junction are from a number
of sources and all pass through Q920. R900 (a current sense resistor in the return
lead of the main coil) develops a voltage proportional to main coil current.
2715 Spectrum Analyzer Service Manual
3- 23
Theory of Operation
This voltage across R926 defines the feedback current to the summing junction
of the operational amplifier. This circuit forces 1st LO main coil current to be
proportional to the sum of the currents from the various control sources, which is
described later. The normal operating current range of the main coil is from
approximately 135 mA to 255 mA.
Q920 is a switch that is normally conducting and consequently has no significant
impact on circuit operation as described. However, it is sometimes necessary to
momentarily set the main coil current to zero in order to standardize frequency
errors due to hysteresis in the 1st LO magnetic structure. When this is desired,
the microprocessor asserts the DEGAUSS line HIGH (by way of the digital
interface circuits), which causes Q931 and Q930 to pull the gate of Q920 to
--8.5 V. This opens the switch, disconnecting the normal input and feedback
paths of the circuit. R929 provides a slight negative feedback in this situation,
ensuring that the main coil current goes to zero instead of to some undefined
value.
The main coil current is the sum of at least two items. First, there is a large fixed
bias current stemming from the reference supply and R923 (trimmed by R931
and U920) to set the 1st LO at 3.01 GHz in the absence of other inputs. Second,
there is a current induced by DAC U950A (and subsequent circuits), which is
used to steer the 1st LO over the range from 2.11 to 3.91 GHz (2.11 to 4.26 GHz
for Option 50 and Option 75). This current is normally a steady state value
selected by the microprocessor to coarsely set the center frequency. Third, if the
instrument is set to a span greater than 5 MHz/div, there is a sawtooth sweep
waveform summed into the main coil current through switch U830A. This
corresponds to the wide span operating mode discussed earlier in the Block
Diagram description.
FM Coil Driver. U811 and U810 together form a buffered operational amplifier
used in the inverting configuration. Input currents to the summing junction come
from a variety of sources, to be described later. R905 is the current sense resistor
for the FM coil. The voltage developed across it results in the current fed back to
the summing junction through R815. Thus, this circuit forces a current through
the FM coil proportional to the sum of the various control currents put into the
summing junction. The normal current range for the FM coil is from approximately --120 mA to +120 mA.
Q910 and Q911 serve as a low resistance switch. When closed (gates held
several volts positive), the FM coil driver operates as described above. When
open (gates held several volts negative), the driver is disconnected and the FM
coil gets its current from R714, which is the situation when the instrument is
phase locked. Control of the switch state is through Q703 and Q800 from the
signal PLLCON--. This signal is LOW when the instrument is phase locked.
Several other switches are also controlled by the same command. R812 keeps
U811 out of saturation when the switch is open.
3- 24
2715 Spectrum Analyzer Service Manual
Theory of Operation
When the FM coil driver is in use (instrument not phase locked) there are two
potential signal sources summed into the driver circuit. One that is always
present is induced by DAC U850A and subsequent circuits. It is steered into
U821 by switch U757A, and serves to finely set the center frequency. The other
is selected only in moderate spans. It is the sawtooth sweep waveform used to
sweep the 1st LO over spans ranging from 50 kHz/div through 5 MHz/div.
Strobe Frequency
Generator (VCO Module)
Functionally, this module is a voltage controlled frequency source. It has an
output frequency range from 25.73 MHz through 26.05 MHz in response to a
tuning voltage range of approximately 4 V to 12.5 V. There is also a switch to
select which of two signals is counted by the microprocessor, and there are
means to turn off the output.
The strobe frequency comes from a VCO that ranges from 102.9 MHz through
104.2 MHz and whose output frequency is divided by four to yield the desired
strobe frequency. Its frequency is controlled by phase locking it (with a 100 MHz
offset) to 1/4 the frequency of a free running VCO (the LFVCO) that operates
over a frequency range of 11.68 MHz through 16.84 MHz. It is this LFVCO that
is actually tuned by the incoming tuning voltage referred to earlier, and this
phase locked loop within the VCO module is called the inner loop. The strobe
signal is generated in this manner in order to control close in phase noise and to
provide a countable signal (the LFVCO output) whose frequency is not
condensed into a very narrow range that would require long times to count to
adequate resolution.
The LFVCO consists of Q426, T430, varactors CR532 and CR540, and
associated components. Output (from the collector of Q422) is made available
for external counting through selector switch U240. The LFVCO output
frequency is also divided by four through U410, and the result is the reference
frequency for the inner loop. U512 and U510 serve as a phase/frequency detector
for the inner loop. The differential output of the phase detector is passed through
error amplifier U435 and becomes the tuning voltage for the HFVCO.
The HFVCO consists of Q522, L610, varactor CR511, trim capacitor C611, and
associated parts. Output is taken from a tap on L610, then split through a pair of
isolation amplifiers (Q400 and Q410 plus Q316). Output from Q400 is divided
by four in U300, providing the useful strobe frequency output of the module.
HFVCO output from Q316 is applied to one input of mixer U320, whose other
input is supplied with 100 MHz energy from the Reference Oscillator. The useful
output of the mixer is the difference frequency between the HFVCO (for
example, 103 MHz) and the 100 MHz reference, or 3 MHz. This signal is
amplified (by Q310, Q312, and so forth.) and applied to the remaining input of
the phase/frequency detector, thus closing the inner loop.
U240 serves two functions; both controlled by the logic signals CNTSELA and
CNTSELB. First, it allows turning the HFVCO on or off by means of Q425.
When the oscillator is turned off, Q101 is turned on at the same time to shut
2715 Spectrum Analyzer Service Manual
3- 25
Theory of Operation
down the strobe driver amplifier in the 1st LO BUFFER module.
Also, U240 serves as a count selector switch. It selects either the LFVCO signal
or the 1st LO beat signal (from the PLCFC board) for counting by the microprocessor. R241 is part of a TTL to ECL level shifter, the remainder of which is
located on the microprocessor board.
U510B provides a lock status indicator for the inner loop so that a lock failure
can interrupt the microprocessor through circuitry on the PLCFC board.
The HFVCO receives supplementary power supply regulation by means of
U122.
The LFVCO receives supplementary power supply regulation by means of U123,
Q223, and associated parts.
1st LO Phase Lock Loop
(Outer Loop) and Beat
Note Processor
The output of the phase gate in the 1st LO Buffer module may either be a beat
note (when loop is unlocked) or a phase error voltage for maintenance of lock.
Thus, the output of the phase gate is split into two paths.
Beat signals in the range of approximately 3 kHz through 11 MHz are passed
through a chain including U614, a low pass filter, U723, and U720. They drive a
Schmitt trigger circuit (Q630 through Q633), which produces a clean rectangular
wave at TTL levels. The desired beat note, noise, and one or more weak,
extraneous beat notes arising from 1st LO harmonics mixing with other
harmonics of the strobe frequency, will normally be within the pass band of the
low pass filter. The level control, R620, sets the overall signal level so that only
the desired beat note is strong enough to overcome the hysteresis designed into
the Schmitt trigger. The Schmitt trigger output may be routed to the microprocessor through a selector switch on the VCO module.
Phase error information from DC through a few hundred kHz is passed through
U606 and switch U700D (when phase lock is invoked) to error amplifier U713.
The output of U713 is applied to the FM coil through R714. When phase lock is
invoked by setting PLLCON to high, U700D is closed and U700C is opened,
closing the outer loop. Nominally, the loop bandwidth is set to 20 kHz. It may
vary considerably from this value due to frequency dependent variations in the
output level and slope of the phase gate. R709 provides for a known drift
direction of the 1st LO tuning when the loop is first closed, but the initial
frequency is away from lock. The instrument firmware purposely sets up a
significant frequency offset in the direction that allows the loop to drift into lock,
as a way of dealing with uncertainties in starting conditions.
The outer loop has a holding range of approximately ±2.5 MHz before U713
saturates. U650A and U650B form a window comparator that generates logic
signals (either INCR MAIN or DCR MAIN) when the loop approaches a range
limit so that the microprocessor can take corrective action (for example,
changing the main coil current in the appropriate direction to recenter the loop).
3- 26
2715 Spectrum Analyzer Service Manual
Theory of Operation
This allows for 1st LO drift or user changes to the center frequency setting
without having to drop and reacquire lock for every change.
If Q652 is turned on by the signal UNLKIND (signifying that the inner loop is
unlocked), both INCR MAIN and DCR MAIN are turned on simultaneously.
This is a unique condition that the microprocessor interprets as a hardware
failure in the VCO module.
Summary of Outer Loop Lock Acquisition. When the instrument is placed into a
situation calling for phase lock operation, several things are done by the
firmware to arrange for a lock at the correct frequency.
The N number (that is, the harmonic order of the strobe to which the 1st LO will
lock) is calculated, and the strobe and corresponding VCO frequencies needed
are calculated. The sweep is disconnected, the FM coil DAC is set to mid range
(FM coil current to nominal zero), and the main coil DAC is set to the value that
will place the 1st LO as close as possible to the desired 1st LO frequency (it can
be several hundred kHz off because of the coarseness of the main coil DAC
steps). Now the VCO is tuned by trial and error so that the strobe line, at a
frequency of N X Fstrobe, is approximately 100 kHz above the actual 1st LO
frequency (that is, the measured beat frequency is 100 kHz on the correct side of
zero beat). Then, lock is invoked by setting PLLCON high. Due to the intentional offset provided by R709, the 1st LO drifts rapidly into lock. After a suitable
delay, acquisition of lock is verified by checking the states of both lock limit
comparators and by checking that the beat frequency is zero.
At this point the loop is locked, but in the wrong spot. Now the microprocessor
proceeds to tune the VCO (and consequently, the strobe and 1st LO) to the
correct frequency by repeatedly tuning and counting the VCO. The sweep is then
switched into the VCO tuning voltage, and the instrument is now scanning the
desired spectrum range.
Signal Path and Switching
Summary
Wide Span Operation (5.1 MHz/div and Higher Spans). The Main coil is driven by a
fixed bias summed with DAC U950A output and a sweep signal (routed through
U830A).
The FM coil is driven with VCFC FM arising from DAC U850A only (routed
through U757A). Current is routed through Q910 and Q911 to the FM coil. See

Figure 3- 14: Phase Lock Center Frequency Control Configuration for Narrow Spans (Locked, Sweep VCO)
The FM coil is driven with the output of the phase lock error amplifier, U713,
only.
The VCO is active continuously and is tuned by a fixed bias summed with
VCFCU from DAC U950B, VCFC L from DAC U850A (routed through
U757D), and sweep voltage VSWP PLL (routed through U757B).
Digital to Analog
Conversion
The PLCFC board has four 12 bit DACs in two IC packages, U850 and U950.
On the digital side, each package has four data lines, three address lines, and two
control lines. The DACs contain internal registers for the 12 bit words associated
with each analog output and, therefore, the microprocessor must write multiple
4 bit words to a package in order to set up a new output.
These are multiplying DACs. Each delivers an output current that is the product
of an analog voltage (called the reference) and the 12 bit digital word. These
units can correctly deal with either polarity of reference voltage. Three of them
(U850A, U950A, and U950B) are supplied fixed reference voltages and serve
simply as computer controlled DC sources.
DAC U850A is called the FM DAC but serves two roles. In non phase locked
spans, its output ultimately ends up fine tuning the 1st LO center frequency
through the FM coil.
3- 30
2715 Spectrum Analyzer Service Manual
Theory of Operation
In phase locked spans, its output is used to fine tune the VCO frequency. In
either case its output passes through U852, which has an output range of 0 to
+5 V. U845 sums that with an offset and provides gain so that the output of U845
ranges from --5 V to +5 V. This signal is called VCFC (L/FM) and is routed to
the appropriate destination by U757A and U757D.
Main Coil DAC U950A output passes through U952 and U940. U940 provides
gain such that the output of U845 ranges from --5 V to +5 V, and the result is
summed with the other components of the main coil current. Its function is
coarse tuning of the 1st LO center frequency, in steps of approximately 400 kHz.
U950B is the PLL DAC. Its function is coarse tuning of the VCO frequency. Its
output is converted to the --5 V to +5 V range by U954 and U941 before being
summed with the other components of the VCO tune voltage.
Unlike the other DACs, U850B’s reference input is supplied with the analog
sweep waveform SWP (from the Sweep board through U565) and serves as a
microprocessor controlled gain control to determine span/div. Its output passes
through U854 to a decade attenuator composed of U831 and associated
components. The output of the decade attenuator is then routed to the desired
destination by switches U830A, U830B, and U757B. In wide spans, this signal
sweeps the 1st LO main coil. In moderate spans, it sweeps the 1st LO FM coil.
In phase locked spans, it is used to sweep the VCO frequency.
Digital Interface
This circuitry links the phase lock hardware with the microprocessor. The link is
bidirectional. Commands and DAC setting data are sent to the PLCFC module,
and lock status information is sent back to the microprocessor. In addition, there
is provision to loop input data back to the microprocessor to verify integrity of
the interface circuitry.
The path into the PLCFC module is through a 24 bit shift register composed of
U361, U460, and U560. Serial data on the DATAO line is shifted into the
register by the clock signal CLKO. When all 24 bits have been shifted in,
CFLATCH-- is used to latch data simultaneously from all shift register stages to
parallel output registers. The resulting 24 bit parallel word is used to control
switches, set DACs, and do a number of other things on the module. A listing of
the 24 lines and their functions appears later in Table 3--22 on page 3--71.
CFCLATCH-- also triggers U372 causing a delayed pulse on the WR-- line,
latching data into internal registers of the DACs.
U370 is an 8 bit shift register used for transferring data from the module back to
the microprocessor. Serial data is shifted out on the DATAI line by the clock
CLKI--, which is gated into the clock input of the register by U270C as
controlled by CFCACK--. Data may be serially loaded into this register through
the EXAM line coming from the tail end of the 24 bit input register. In this
situation the data is clocked into the register by a derivative of CLKO, which is
gated by LOADEXM through U270D.
2715 Spectrum Analyzer Service Manual
3- 31
Theory of Operation
This is the loop back path referred to earlier for checking the interface. This
register may also be loaded with up to eight bits of parallel data for subsequent
serial transfer to the microprocessor. Only three bits are used. Bits 7 and 8 are the
signals (INCR MAIN and DCR MAIN) from the lock limits comparator, and bit
5 is wired to logic 1 as a board identity.
The gating of CLKI-- and CLKO into the output shift register (by CFCACK-and LOADEXM, respectively) is partly a matter of source selection and is also
necessary because both clock signals are used by other boards in the system at
some times.
Any transition on either INCR MAIN or DCR MAIN (or both) will load the new
states of those lines into the output shift register. (The various sections of U360
serve as edge detectors to generate the load command to the shift register.)
Further, if LKINTEN is high at the time, U471B will end up SET, interrupting
the microprocessor by way of CFCREQ--. The line READEXM provides a direct
method of setting the interrupt, if desired. Any transition on LKINTEN will also
cause the shift register to be loaded, providing a forced means for checking the
status of the lock lines at any time. The microprocessor uses CFCACK-- to clear
U471 of the interrupt (in addition to the gating function mentioned above).

Variable Resolution Module

Input Amplifier
The input amplifier used is a transformer feedback stage that provides approximately 12 dB of gain with 10 dB of reverse isolation. See Figure 3--15. The
match at each port with the other terminated is better than 15 dB at 10 MHz. The
noise figure is less than 3 dB and, with 12 mA flowing in the device, the output
intercept is approximately +30 dBm. The match at each port is highly sensitive
to a proper termination being presented to the other port.

PIN Attenuator
3- 34
The PIN attenuator design is based upon a pair of matched pin diodes used in a
tee configuration. This configuration maintains the impedance match at each end,
providing the product of the PIN diode resistances is equal to the square of the
end terminations. This can be approximated if the sum of the currents in the PIN
diodes is equal to a constant. The DAC has complementary current outputs
whose total is set by an adjustment. The attenuation range is approximately
12 dB with a 1 dB minimum loss. The worst case return loss at the end points is
15 dB. The step size for an 8 bit DAC is 0.04 dB steps in the center of its range.
2715 Spectrum Analyzer Service Manual
Theory of Operation
10 dB Gain Step Amplifier
The 10 dB gain step stages incorporate a transformer feedback amplifier. These
stages have approximately 0.5 dB of loss or 9.5 dB of gain, for a net difference
of 10 dB. When the gain step is selected, the signal is routed through the
amplifier for a gain of approximately 11.5 dB. A pad of approximately 1.5 dB is
added to trim the gain down to 10 dB. The signal is then routed through a switch
that has approximately 0.5 dB of loss. When the amplifier is deselected, the
signal is routed around the amplifier, thus preserving noise figure and intercept
point. A total of five step gain stages are used.
1 dB Gain Step Amplifier
The 1 dB gain step amplifier is the last amplifier before the filter switching tree.
The amplifier is composed of a class AB, three stage, feedback amplifier. The
gain is adjusted in 2 dB steps for a total of 10 dB. The 1 dB steps are done by
shunting part of the signal to ground. This is controlled by Q246, located at the
input of this amplifier. This configuration allows the entire 10 dB gain sequence
to be contained within one step gain stage.
Routing Switches
The routing switches are used to route RF signals to various areas. They are
composed of a transistor in heavy saturation that has relatively large charge
storage characteristics. The topology used is a shunt series configuration. These
switches are used on both the input and output of each filter including the
external filter connection.
RF Options
The RF Options is a system of additional resolution bandwidth filters that
enhance the measurement capability of the instrument. See Figure 3--16.

Theory of Operation
The board provides the resolution bandwidths used to fill in between filter values
installed within the Variable Resolution module. The bandwidth range is 1 MHz
to 1 kHz in decade steps, and 300 Hz. Each filter path consists of a switchable
amplifier and bandpass filter combination.
Control System Interface
Bandwidth Control
Identification Bit
The control of the RF Options by the microprocessor is through one 8 bit shift
register. Data is shifted serially in one 8 bit word.
The variable bandwidth section consists of a switching tree to select one of five
filters. Available bandwidth filters, in addition to those already in place in the
Variable Resolution module, are 1 MHz, 100 kHz, 10 kHz, 1 kHz, and 300 Hz.
A resistor is installed between either pin 12 (d6) or pin 13 (d5) of shift register
U390 and the base of Q396 to complete a path for an identification bit for the
Microprocessor. This allows the Microprocessor to determine that the 300 Hz
filter is installed on the RF Options board.
Gain Stage
The gain stage used is a transformer feedback stage that provides approximately
11.5 dB of gain. In the case of the 100 kHz and 300 Hz filters, two gain stages
are used. The impedance match at one port of the Gain Stage is highly sensitive
to a proper termination being presented to the other port.
Routing Switches
The routing switches are used to route RF signals to the selected bandwidth
filter. They are composed of a transistor in heavy saturation that has relatively
large charge storage characteristics. The topology used is a shunt series
configuration. These switches are used on both the input and output of each
filter. That is, the filters are switched in and out at both the input and the output
so that when a filter is not being used it is effectively out of the circuit.
Each bandwidth filter is composed of a double tuned circuit (a two pole
Butterworth filter section), an amplifier to provide gain correction and isolation,
and another double tuned circuit. The intermodulation performance of the
amplifier is less critical because the amplifier is placed after the filter. The noise
power generated by the stage is reduced by placing a filter of equal bandwidth
after the gain stage.
Diagnostics
The identification bit can provide useful information on the proper configuration
of the instrument.
2715 Spectrum Analyzer Service Manual
3- 37
Theory of Operation
Log Amplifier
The Log Amplifier system is a high performance, intermediate amplifier system
that provides display laws of linear detection and logarithmic detection of the
incoming signal. The log display has scale factors of 10 dB/div, 5 dB/div, and
1 dB/div. The linear mode has the ability to magnify the top portion of the
waveform to enhance the measurement capability. The module also contains an
FM detector, which, when used with the built in audio amplifier, can be used to
monitor the modulated input signal for enhanced signal identification. The audio
amplifier can also be used to monitor the output of the displayed waveform
regardless of the video source. There is an alternate audio input for the push
button clicks generated by the system controller. This audio signal is also used
for the vertical amplitude reference, to check the sweep speed, and for internal
triggers. An amplitude limited output is available for the period counter for
determining the actual frequency of the signal present in the IF system. External
video inputs are provided for the use of external detectors and the rear panel. A
provision is made for clamping the display when the 1st LO is tuned out-ofband. Frequency dependent amplitude (flatness) correction is also performed on
this board.
Hardware
The Log Amplifier system is configured by using a 4.5 by 8.75 circuit board
mounted in the card cage. The Microprocessor interface is through three 8 bit
shift registers.
Flatness Error Correction
The signal level at the Log Amplifier board (J190) for full screen deflection is
--10 dBm. The first stage of the Log Amplifier is an amplifier that provides gain
between 18 dB and 24 dB, depending on the frequency of the 1st LO. The
amplifier is adjusted such that the gain is 18 dB at low frequencies and is up to
24 dB at the high end of the frequency range, because the frequency dependent
amplitude error is always greater at the higher frequencies. The feedback is
adjusted by changing the amount of current flowing through PIN diodes CR290
or CR291. The correction voltage, SWPSLOPE, reflects the frequency of the 1st
LO. Provision for a second correction voltage from a future Digital Signal
Processing module is included. This second correction voltage, which provides
an interpolated voltage, will be derived from a flatness table. At present, only
SWPSLOPE is used.
Noise Filter
The output of the first stage, a gain slope amplifier, is then fed to a two pole
noise filter to limit the noise to 5 MHz and to provide two more poles of 5 MHz
bandwidth resolution filtering. The output of this filter is then sent to the log
stages through a set of jumpers so the signal can be broken for calibration
purposes and buffer amplifier Q170 (in a common base configuration) to form an
auxiliary IF output.
3- 38
2715 Spectrum Analyzer Service Manual
Theory of Operation
Logarithmic Amplifier
Stages
The core of the logging stage is a pair of AD640s. The AD640 uses five
cascaded limiting amplifiers to approximate a logarithmic response to an input
signal of wide dynamic range and wide bandwidth. The two AD640s are used in
a parallel/summing operation. The input signal to one AD640 is amplified by
25 dB with the CLC501. This is a current feedback operational amplifier that has
a clamping circuit used to limit the output to a value set by an external voltage
divider. The other AD640 is fed through a 25 dB attenuator. The difference in
input amplitude for small signals is then 50 dB. There is not enough gain in the
75 dB path to cause the AD640 to limit on the input noise of the CLC501. Thus,
the full dynamic range of both parts is realized. This topology eliminates the
need for a narrow bandwidth noise filter.
Synchronous Detector
In Lin mode, the signal envelope is extracted from the RF carrier by the use of a
synchronous detector. This detector is basically a multiplier. Detection is
accomplished by feeding a limited signal into one input and a sample of the RF
signal into the other. Since the limited input is always considered equal to plus or
minus one unit, only the polarity is important. The sample RF is then multiplied
by plus or minus one. Since the RF is always in phase with the limited input, the
product is always positive. Thus, demodulation is achieved.
Ripple Filter
The ripple filter is a six pole elliptic filter with a finite transmission zero at the
10 MHz IF frequency and another at approximately 19 MHz. The purpose is to
remove any of the remaining 10 MHz component that may still exist. Because of
the full wave rectification provided by the synchronous detector and the log
cells, the 10 MHz component is attenuated by approximately 30 dB. This greatly
reduces the requirements of the ripple filter. However, the signal is not always at
10 MHz. The widest bandwidth is 5 MHz, so there is still a significant requirement for ripple reduction as low as 5 MHz.
Video Filter/Scale Factor
After the Ripple Filter, the signal is offset before being amplified to bring the
equivalent of a full screen signal in log mode or linear mode to correspond to
0 V output. The out-of-band clamp is also done at this time to deflect the CRT
beam into the bottom of the screen when the display is outside the frequency
limits of the Spectrum Analyzer. Next, the video filter selector is chosen. The
bandwidth of the vertical chain is approximately 5 MHz. Therefore, when a
video filter path is chosen, the maximum bandwidth drops to approximately
1 MHz. This switching tree also multiplexes in the external signals from the rear
panel or the FM Detector.
2715 Spectrum Analyzer Service Manual
3- 39
Theory of Operation
Immediately following the Video Filters is the Scale Factor amplifier. The gain
of the Scale Factor amplifier can be set to 1.1, 2.2, 5.5, or 11 corresponding to
10 dB/div, 5 dB/div, 2 dB/div, or 1 dB/div. The linear function is done with the
gain set to 1.1.
FM Detector
The AD834 (U350) is a four quadrant multiplier that is used as a quadrature
detector for demodulation of FM signals. The audio output is sent to the audio
amplifier selector and to the video input selector.
Period Counter Signal
The limited output of one of the log cells is used to drive an isolation buffer
(U630A). This signal is used to drive the period counter on the Microprocessor
board for frequency measurements.
Audio Amplifier
The TDA1013A is used as the audio amplifier for monitoring purposes, and as a
means of providing feedback to the user from the microprocessor.
Video Amplitude
Calibrator
Microprocessor audio appearing at pin 22 of J7 is used to provide feedback to
the operator for push button clicks and out of range or uncalibrated conditions.
This signal is also used to provide a signal for calibrating the video amplifier and
display storage. The sweep triggers are also tested by this signal.
System Reset
At power on, the system reset line SYSRST-- on pin 4 of J7 goes low until the
Microprocessor resets it. During this time, the control latch’s output enable line
is held false and the outputs are in a high impedance state. This is used only by
the mute bit. The pull up resistor will force a mute condition during this time,
thus disallowing any extraneous noise from the speaker.
Display Storage
The Display Storage board digitizes both vertical (LOGVID) and horizontal
(SWP) signals and places this digitized information in nonvolatile RAM
(NVRAM). Various state machines on the board then take this digitized data
from the NVRAM and generate the horizontal and vertical signals which are sent
to the deflection circuitry on the Power Supply board. In addition to displaying
the digitized data, the Display Storage board also is used to display the readouts
and place markers on the CRT.

Marker Position Registers. There are two Marker Position Registers. One register
for Marker 1 and a second register for Marker 2. Marker Position Register 1 uses
I/O port locations 0x0FC00 through 0x0FDFF. Marker Position Register 2 uses
I/O port locations 0x0FE00 through 0x0FFFF. Each port location corresponds to
a horizontal position on the screen. By writing any data to one of the I/O ports
inside the above range, the corresponding marker will be placed at the horizontal
position, on the CRT, represented by the lower nine bits of the port address.
For example, writing 0x55 to I/O address 0x0FCE3 will place Marker 1 at
horizontal screen position 0x0E3 (227), while writing 0xA1 to I/O address
0x0FFF9 will place Marker 2 at horizontal screen position 0x1F9 (505).
Circuit Description
The Display Storage board is best described by breaking it up into several
sections. These sections include Address Buffering and Decoding, the Control
Registers, the Horizontal Input and Tracking A/D, the Vertical Input, the Vertical
Data Processor and NVRAM, the Readouts and Waveform Drawing, the
Horizontal Output, the Vertical Output, and the Miscellaneous Decoupling. The
following sections will describe each one of these in detail.
Address Buffering and Decoding. The Address Buffering and Decoding section
consists of a 74HCT245 bidirectional bus transceiver (U22), and a GAL20V8
PAL (U29). The purpose of this section is to decode the incoming address lines
into the various enable signals required by the Display Storage board, buffer the
data lines from the CPU Board, and buffer the BCLK signal for distribution
around the board.
U22, the bus transceiver, is used to allow data on or off the Display Storage
board. This bus transceiver can only be enabled after the RAM arbitrator grants
access to a request from the Microprocessor.
The PAL, U29, decodes the address lines BA19 through BA9, to generate the
request signal UPREQ, and the enable signals PORTVEC, MKR1_LT, and
MKR2_LT. In addition the signals RDEN and WREN are generated on read or
writes to or from the board. The memory map (Table 3--11) shows which signals
are generated from which address ranges. A description of each signal from U29
is given below.
UPREQ. This signal becomes active (high) any time the board is accessed by the
CPU. The UPREQ signal is fed into the RAM arbitrator to request access to the
board.
PORTVEC. This signal becomes active (high) at any access to the Control
registers (I/O port addresses 0xFA00 through 0xFBFF). This signal also causes
the UPREQ signal to become active.
MKR1_LT. This signal becomes active (high) at any access to the Marker 1 port
addresses (I/O port addresses 0xFC00 through 0xFDFF). This signal also causes
the UPREQ signal to become active.
2715 Spectrum Analyzer Service Manual
3- 47
Theory of Operation
MKR2_LT. This signal becomes active (high) at any access to the Marker 2 port
addresses (I/O port addresses 0xFE00 through 0xFFFF). This signal also causes
the UPREQ signal to become active.

The following paragraph describes a typical CPU read or write of the Display
Storage board.
The CPU begins by presenting the read or write address to the Display Storage
board on the BA<19..0> lines. The upper eleven address lines (BA<19..9>) are
fed into the address decoder PAL, U29. If the address is inside the range for the
Display Storage board the UPREQ signal becomes high, and the appropriate
enable signal becomes active (PORTVEC, MKR1_LT, or MKR2_LT). The
UPREQ signal is a request for access to the Display Storage board, and it feeds
the RAM arbitrator. As soon as the UPREQ signal becomes active, the CPU
BWAIT_L signal is pulled low, forcing the CPU into a wait state. The CPU will
remain in this wait state until the RAM arbitrator allows the CPU to access the
board. The RAM arbitrator will bring the UPGRNT_L signal low, when it is
ready to allow the CPU to access the Display Storage board. When UPGRNT_L
goes low, the data bus transceiver, U22, is enabled as well as the RDEN and
WREN signals to the rest of the Display Storage board.
3- 48
2715 Spectrum Analyzer Service Manual
Theory of Operation
Control Registers. There are five control registers on the Display Storage board
which are used to set the various operating modes for the board. All of the
control registers are read/write registers, with the exception of the Scroll
Register. The Control Register section consists several 74HCT273 latches and
74HCT541 tristate buffers, and two 74F138 decoders.
Each control register is made up of a 74HCT273 latch and a 74HCT541 tristate
buffer. During power up each control register is cleared to all zeros, allowing the
board to start at a known state. Table 3--12 gives the reference designators for
both the latch and tristate buffer used for each control register. The two 74F138
decoders are used to decode the BA2, BA1, and BA0 address lines to select the
appropriate register. There is one decoder for writing to the control registers,
U16, and one for reading from the control registers, U17. Both decoders are
enabled by the PORTVEC signal from the Address Decoder Section and either
the WREN or RDEN signal (depending on whether the microprocessor is
reading or writing the Control Registers).

As mentioned earlier the Scroll Register can’t be read by the microprocessor.
This is to allow the ability to read the contents of the Maximum Accumulator in
the Vertical Waveform Processing Section.
The Display Storage board also provides an additional control register, Mode
Control Register 2 to protect against accidental writes. This protection is an
enable bit (MCREG2) located in the MSB of the Scroll Register. While the
MCREG2 bit is low, Mode Control Register 2 is held in the cleared state. When
MCREG2 is brought (and held) high, Mode Control Register 2 can be written. If
at any time MCREG2 goes low, Mode Control Register 2 will be cleared.
There are also two 74HCT541 tristate buffers (U32 and U33) which are used to
buffer the address lines on to the internal (Display Storage board’s) address bus.
U32 and U33 are enabled by the UPGRNT_L signal from the RAM Arbitrator.
A typical write to the control registers is described in the following paragraph.

The CPU starts a write cycle to the Display Storage board, presenting the
appropriate address for the desired port. The PORTVEC signal becomes active,
enabling one of the enable inputs on both of the decoders, U16 and U17. As soon
as the RAM arbitrator allows access to the Display Storage board, the WREN
signal becomes high, completing the enabling of the decoder, U16. The lower
three bits of the address (BA<2..0>) are then decoded to select the desired
register. The desired output of the decoder will then go low and stay low until
the WREN signal goes high. This rising edge of the WREN signal brings the
desired decoder output high, latching the data present at the data inputs of the
desired control register. The steps are identical for a read, except that the tristate
buffer is enabled, placing the contents of the latch on the RAMD<7..0> data bus.
Horizontal Input and Tracking A/D. The Display Storage board uses a
tracking A/D converter to follow the SWP signal. A tracking A/D guarantees that
the digital output is monotonic. A tracking A/D operates by taking the input
voltage and summing it with the output of a D/A converter. A summing node,
the output of the D/A converter, is then fed into the inputs of two comparators.
One comparator determines if the summing node is less than a reference point,
and another comparator determines if the summing node is greater than a
reference point. The difference between the two reference points is called the
comparator window. The outputs of the comparators are then fed into a digital
state machine, which is used to either increment or decrement a counter,
depending on the state of the comparator outputs. The output of this counter is
fed into the D/A converter.
On the Display Storage board, the SWP signal is fed through an MC34001
operational amplifier, U36, running at a voltage gain of about --2. The output of
this operational amplifier is fed through a summing resistor, which consists of
R38 and R40. These two resistors sum the voltage output of the operational
amplifier with the current from a DAC312, U11. R40 (HIG) can be adjusted to
determine the gain of the tracking A/D. The offset for the tracking A/D is
adjusted using the resistors R37 and R39 (HIO). The offset works by adding
more current to the summing node.
3- 50
2715 Spectrum Analyzer Service Manual
Theory of Operation
The comparators are contained in an LM319, U9. The top (UP) comparator
determines if the summing node is greater than the 49.5 mV reference point. The
bottom (DN) comparator determines is the summing node is less than the 0.0 V
reference. The outputs of these two comparators, UP and DN, are fed into the
Horizontal LCA. Inside the Horizontal LCA the UP and DN signals are
debounced to prevent false changes in the internal counter. Also inside the
Horizontal LCA is a small state machine which decodes the debounced UP and
DN signals, the SWPGATE signal, and the internal counter, to determine
whether to increment or decrement the internal counter.
A typical sequence of events for the tracking A/D converter are described in the
following paragraph.
First assume that the summing node starts a stable point and a valid sweep is
running. The SWP signal begins to increase. Once the output of U36 has
increased enough to force the summing node above the positive reference point
of 49.5 mV, the output of the top comparator, UP signal, goes high. This signals
the state machine inside the Horizontal LCA to increment its internal counter.
The outputs of this internal counter are fed back to the U11, increasing its sink
current, bring the summing node back inside the comparator window. At the
transition of the internal counter to a new value, the signal EOB (End Of Bin)
goes high until all data has been written into waveform memory. The reverse
procedure occurs for a SWP signal that is decreasing.
The timing diagram show in Figure 3--18 depicts a section of a typical sweep for
the Horizontal Tracking A/D Converter.

Vertical Input. The purpose of the Vertical Input section is to provide gain and
offset to the incoming LOGVID signal prior to a flash A/D Converter (ADC).
The LOGVID signal is amplified by operational amplifier U2, an NE5534. U2 is
configured as an inverting amplifier with a gain of about --3.5. Input signal gain
is adjusted using R24 (VIG), while input offset is adjusted using R20 (VIO). The
output of U2 is then passed through a resistive divider, which reduces the output
2715 Spectrum Analyzer Service Manual
3- 51
Theory of Operation
voltage by about one third. The signal is then passed through a diode, CR2 and
an emitter follower, Q3, and then into U1, an MC10319 Flash ADC running at
2.4576 MHz. Transistor,Q3, provides the low input resistance required by the
ADC. Eight bits of vertical data are output by U1 at each falling edge of the
clock. An 74HCT04 inverter attached to the OVRNG (over range, pin 3) pin of
U1 drives an LED which illuminates when the voltage at the input exceeds the
reference voltage (VRT, pin 28). Test point TP1 can be used to probe the
OVRNG pin if necessary.
In order to protect the analog input and reference voltage inputs of the ADC, the
input amplifier section is required to clamp the incoming LOGVID signal
between ±2.3 V. The input amplifier clamps in the negative direction at --0.7 V,
due to diode CR2. The diode in the output of U2 prevents the operational
amplifier from going below ground, which in turn limits the voltage at the
emitter of Q3 to about --0.7 V. Clamping in the positive direction occurs when
the operational amplifier reaches its positive rail, the signal is attenuated by the
resistive divider, R29 and R31, and then shifted down by two diode drops. This
prevents the signal from exceeding the positive input voltage specification of U1.
There are also three reference supply circuits on this section. The main reference
supply is +VR, at +5 V. It is generated using a TL431 precision Zener reference,
buffered through U5, one half of an MC34002 operational amplifier and then
driven by Q1, a BCX68 npn transistor. Power dissipation on the output transistor
for +VR requires an SOT--89 style package. A negative reference supply is
generated from +VR. This negative reference is --VR, at --5 V. The other half of
U5 is used to buffer this supply. --VR is driven by Q7, a BT3906 pnp transistor.
The final reference supply is the +2 V reference for the ADC. This supply is also
generated from the +VR supply. It is buffered by another MC34002, U4. The
output transistor for this reference supply is Q2, a BT3904 npn transistor.
Vertical Data Processor and NVRAM. The Vertical Data Processor and NVRAM
section performs all of the waveform data processing, storing, and nonvolatile
RAM (NVRAM) arbitration. It consists of an XC3042 LCA (U15), a single
XC1736 serial configuration PROM (U14), two TC55257 32K by 8 SRAMs
(U13 and U30), and two DS1210 Nonvolatile Controller ICs (U6 and U28).
At power up U15, the Vertical LCA, will wait until the BDRST_L signal
becomes high and then begin configuring itself from the contents of U14, the
serial configuration PROM.
During normal operation U15 receives data, at the falling edge of BCLK,
directly from the A/D Converter via the VAD<7..0> bus. This data is manipulated inside U15, depending on the acquisition mode, and then written to the
NVRAM. If the acquisition mode is Max Peak, the incoming data is compared
against the data already stored in the Max Accumulator (a register internal to
U15). If the incoming data is greater than the Max Accumulator then the
incoming data becomes the new value stored in the Max Accumulator.
3- 52
2715 Spectrum Analyzer Service Manual
Theory of Operation
At the end of a horizontal bin the contents of the Max Accumulator will be
written to waveform memory.
If the acquisition mode is Min Peak the same comparisons occur as in Max Peak
acquisition mode, except that the Min Accumulator is used. At the end of a
horizontal bin the contents of the Min Accumulator will be written to waveform
memory.
If the acquisition mode is Min/Max then the same comparison occur as in Max
Peak acquisition mode, except that both the Min and Max Accumulators are
used. At the end of a horizontal bin the contents of either the Max or Min
Accumulators will be written into waveform memory, depending on whether the
horizontal bin was even or odd and whether noise was detected or not. Noise is
defined as both the Min and Max Accumulator being written with a new value
sometime during the horizontal bin. Table 3--13 shows the algorithm used to
write data to the waveform memory at the end of a horizontal bin.

If the acquisition mode is Sample the incoming data is automatically placed in

the contents of the Max Accumulator are written to waveform memory. This
effectively places the last acquisition, from the ADC, into waveform memory.
The timing diagram in Figure 3--19 shows the sequence of events required when
writing data to the waveform memory.

The two DS1210’s, U6 and U28, are used to provide battery backup power to the
RAM devices while the instrument is in the off state.
Readouts and Waveform Drawing. The Readouts and Waveform Drawing section
places all readouts and waveforms on the CRT screen. It does this using an
XC3042 LCA (U46), a CY7C291 PROM (U48), two 22V10 PALs (U39 and
U40), a 74HCT541 buffer (U47), and three 74HCT257 quad 2--1 multiplexers
(U50, U51, and U52).
The easiest way to view the display section of this board to look at it as if each
waveform or screen of text were a page. There are eight pages, four pages of
waveforms (waveforms A through D) and four pages of text (one for readouts
and 3 more for menus). U39 and U40 form a state machine called the Readout
State Machine which is used to turn the CRT beam on and off, load data for
display from RAM, and determine which pages should be displayed. The
Readout State Machine begins by determining which page needs to be displayed,
starting with page 0. By taking the contents of the Display Control Register (U21
and U25) and comparing it to a 3 bit counter (Page Counter, internal to U46) it
can be determined which pages need to be displayed. For example if DISPA is
high and the page counter is at zero, then Waveform A should be displayed. This
comparison is performed in U40. Once U40 determines that a page should be
displayed, the Readout State Machine will then load the appropriate data and
display the page. Depending on whether the page to be displayed is text or
waveform, the Readout State Machine takes one of two paths.
Table 3--14 illustrates the relation between the page counter, page number and
the waveform or text page.

If the page to be displayed is a waveform then the address for the waveform data is
determined by the lower two bits of the Page Counter and the position of the
waveform is determined by the Horizontal Counter (inside U46). This combination
of bits is placed on the boards address bus using U50, U51, and U52, the three 2--1
multiplexers. The waveform data is then read through a tristate buffer, U47, into the
LCA, U46, and latched. The CRT beam is then turned on and the waveform data is
presented to the Vertical Output DAC, drawing a vector on the CRT.
If the page to be displayed is text then the address for the text data is determined by
the lower two bits of the Page Counter, the upper four bits of the Character Row
Counter (inside U46), and the upper eight bits of the Character Column Counter
(inside U46). This combination of bits is placed on the board’s address bus using
U50, U51, and U52. The text data is then placed at the inputs of the Character
ROM, U48. The character ROM outputs then provide one column of bit information for the character to be displayed. The character bit information is then latched
inside U46 and fed out serially and used to control the CRT beam. If a one (high) is
encountered in the character bits, the CRT beam is turned on for five clock cycles
(2.44 uS), displaying a dot on the CRT. The text continues to be placed on the CRT
using a vertical scan method. A vertical scan is used to decrease the time required
to wait for the beam to move from the top back down to the bottom of the CRT.
Figure 3--20 shows how a vertical scan is performed.

Horizontal Output. The Horizontal Output section uses a DAC312 (U41), an
operational amplifier (U45), and DG444 analog switches (U43 and U34), to
generate the DSHOR signal, which is in turned used to deflect the CRT beam on
the Power Supply board. The DAC312 is a twelve bit DAC that, has had its
lower three bits tied to ground to turn it into a nine bit DAC. The DAC receives
data from the Readout LCA (U46), and converts it into a horizontal position on
the screen. The output of the DAC is then converted to a voltage via R95 and
R97. This voltage is then amplified by an MC34001 operational amplifier (U45).
Added to the DAC output is a 3300 pF capacitor, C96. This capacitor is required
to remove the glitch current on the DAC output at major code transitions.

Theory of Operation
Offset, (HOO) R98, are provided. In addition part of U34, an analog switch, and
another resistor are added in parallel to the feedback resistor of the operational
amplifier to allow gain reduction while the readouts are being drawn. This will
allow the waveform to extend beyond the edge of the graticule and still allow the
readouts to be visible.
There are also two analog switches which are used to multiplex between the
digitized information (HORIZ signal) and the analog trace (SWP signal) during real
time displays.
Vertical Output. The Vertical Output Section converts the vertical data from the
Readout LCA (U46), into the DSVER signal, which is then used to deflect the CRT
beam by the Power Supply. There are two paths through the Vertical Output Section.
A high bandwidth path for the readouts and an integrator path for drawing the
waveform vectors. Both the waveform and readout paths will be described in the
following paragraphs.
The waveform path of the Vertical Output Section uses an integrator to draw the
vectors between each point in a waveform. A block diagram of the integrator is
shown in Figure 3--23. The integrator consists of an Error Amplifier, a Sample and
Hold, and the Integrator.

The Display Storage. The Error Amplifier consists of an LM318 (U53), a BT3904
transistor (Q4), and a BT3906 transistor (Q5). The Sample and Hold consists of
part of a DC641 (U34), capacitor C94, and half of a TL072 (U57). The integrator
consists of one half of a TL072 (U57) and capacitor C93.
Digital data is fed into an eight bit DAC--08 from the Readout LCA. The current
output of the DAC is converted to a voltage ranging from 0.170 V to 1.30 V.
This is then fed into a unity gain buffer to drive the Error Amplifier of the
Integrator circuit.
3- 58
2715 Spectrum Analyzer Service Manual
Theory of Operation
The Error Amplifier compares the current state of the Integrator Circuity output
and the current input voltage from the DAC and generates an error voltage. This
error voltage is then fed into a high current buffer made up of Q4, Q5, and CR7.
CR7 and R179 are used to insure that transistor Q4 is properly biased. The high
current buffer is required to ensure that the capacitor in the Sample and Hold
section is charged quickly. The Sample and Hold circuit basically samples the
error voltage by closing the analog switch, U34, for 400 ns, charging capacitor
C94. When the switch opens the value of the error voltage should be across the
capacitor. The operational amplifier U57 then buffers and amplifies the error
voltage such that when it is applied to the Integrator sexton ramp the correct
slope is produced. The potentiometer, R181, Vector Length, is used to adjust the
slope of the output ramp to match the waveform data drawing rate. The input of
the Integrator section consists of two resistors with a capacitor to ground
between them. This RC network, along with the resistor in series with the
integrating capacitor, C93, form a network that prevents an early step when
integrating over a long distance. The step is caused by the rapid change in error
voltage coupling straight through the integrating capacitor. The resistors R112
and R183 along with capacitor C93 and operational amplifier U57 form the
Integration Section of the Integrator. The output of the Integrator is then fed
through a DC641 analog switch and into the output buffer, U35, of the Vertical
Output Section. Finally a potentiometer, R174, Vector Offset, is provided to
compensate for the injection charge of the DC641 into the hold capacitor, C94.
The signal for drawing the Readouts is taken directly off U4, the DAC current to
voltage buffer, and fed through an analog switch into the output buffer. The gain
variations between the waveform and readout is accomplished by slightly
increasing the gain of the Integrator, such that the Readouts will always remain
inside the graticule. In order to ensure that the Readouts will always appear
centered inside the graticule, the waveform is forced slightly lower by adjusting
the Vertical Offset to +40 mV. Then when the waveform display is centered on
the screen using the Vertical Output Offset potentiometer everything aligns
correctly.
The final buffer in the Vertical Output Section provides both gain and offset
adjustments, Vertical Output Gain (VOG), R42, and Vertical Output Offset
(VOO), R63. The two analog switches which drive the DSVER signal are used
to switch between the LOGVID signal, for real time analog display, and the
VERT signal for digitized display (readouts).
Miscellaneous Decoupling. Contained on the Miscellaneous Decoupling page of
the schematics are all of the decoupling capacitors. There is one 0.1 F capacitor
for each digital integrated circuit on the board. Also shown on this page are
several 221 Ω resistors. These resistors are required to restore the power
dissipation to a minimum level to ensure that the power supply can maintain its
supply voltages well centered.
Power Up Reset. The power up reset circuit is included to ensure that a valid reset
signal is generated when the instrument is turned on.
2715 Spectrum Analyzer Service Manual
3- 59
Theory of Operation
The Power up reset circuit consists of a TL7705 Power Supervisor IC. This IC
monitors the +5 V supply and generates a reset signal on power up. The
capacitor, C101, is used to delay the rising edge of BDRST_L for about 50 ms.
This ensures that if the +5 V supply falls below 4.5 V, the BDRST_L signal will
remain low for a minimum of 50 ms, and that the LCA will go through a valid
reset cycle and reprogram correctly.
Microprocessor
The Microprocessor board is the central processing section of the instrument. It
is used to control all instrument functions including frequency control, implementation of the human interface, and external port communication through the
GPIB or RS--232C board. The Microprocessor contains the following circuit
blocks (Figure 3--24):

Figure 3- 25: Microprocessor Counter System (CPU)
Microprocessor (CPU)
The Microprocessor (CPU) is based on an 8 MHz NEC PD70108 (V20).
The V20 is configured in the minimum mode (pin 36 connected to Vcc) using a
demultiplexed bus. In the demultiplexed bus configuration, the address bits
(AD0 through AD7 and A8 through A19) are presented to the address latches
(U440, U450, U465), and the falling edge of ALE (pin 28 of U250) latches the
address lines. Approximately one clock cycle later, the data lines (AD0 through
AD7) become active for either a read or write operation. (Notice that the AD0
through AD7 lines provide both the low order eight bits of address and the eight
bits of data.) The DIR signal (pin 30 of U250) determines the direction of data
flow on the data lines. This signal is used to set the direction of the bidirectional
data buffer (U460).
Once the address lines have been latched, they are decoded using the Programmable Logic Devices (PLDs) U515 and U530, and the 4 to 16 line decoder,
U585. The outputs of these PLDs are used to enable the various peripheral
sections of the board.
3- 62
2715 Spectrum Analyzer Service Manual
Theory of Operation
Clock Generator
The Clock Generator chip (U360) is an NEC PD71011. The purpose of this IC
is to generate the clock for the Microprocessor board and synchronize the
insertion of wait states into the CPU.
The Clock Generator part of the IC uses a 14.7456 MHz crystal (parallel
resonant) to generate the 7.3728 MHz CPU clock (14.7456 MHz ÷ 2). In
addition to the CPU clock output, there is an oscillator clock output that is
divided by six (÷6) using three flip flops (U240). The output of this ÷6
(2.4576 MHz) is used to drive the Display Storage and GPIB or RS--232C board
state machines.
The wait state synchronization part of U360 is not used but is replaced by a flip
flop (U260A). Timing errors between a wait state generator on the GPIB or
RS--232 board and the CPU are eliminated by synchronizing the RDY signal
(pin 25 of U250). Since the CPU allows the RDY line to go low asynchronously,
relative to the CLK88 signal, U260A is cleared as soon as the BWAIT-- signal
goes low. After the BWAIT-- signal goes high, the RDY signal is synchronized,
through U260A, using the CLK88 signal. This prevents any timing problems
regarding the generation of wait states.
Interrupt Controller
The Interrupt Controller (U340) is based on the NEC PD71059 (Intel 82C59).
The purpose of the Interrupt Controller is to synchronize and set up priority for
up to eight system interrupts. A high level on any of the IR0 through IR7 inputs
of the Interrupt Controller causes the INT output (pin 17 of U340) to become
high. After the CPU recognizes the interrupt on the INTR input (pin 20 of
U250), it pulls the INTA output (pin 27 of U250) low, telling the Interrupt
Controller that the CPU is ready to accept the interrupt data. The Interrupt
Controller then disables the data buffer outputs (U460), through XDEN-- on
pin 20 of U530, and presents the interrupt data on the data bus during the second
low pulse on the INTA signal from the CPU.
The interrupt inputs to the Interrupt Controller are configured as shown in
Table 3--15. The priority is determined by both the settings of the internal
registers of the Interrupt Controller and the interrupt input number (IR0 has
highest priority by default).

I/O Subsystem Interface
The I/O Subsystem performs the serial communication between the CPU and
other modules in the instrument, controls the Interval Timers, and triggers single
sweeps.
The signal SSTRIG (pin 5 of U495) is used to trigger the single sweep mode of
the instrument. This signal is selected by writing a one to the second LSB of the
I/O Subsystem Control Register.
The I/O Subsystem Control Register is also used to control some parts of the
Interval Timer (U580). The signal, GATE_0 (pin 6 of U495), is used to enable
Timer 0 of the Interval Timer depending on how the counter is set up.
The signal AUDEN is used to enable Timer 2 of the Interval Timer. This timer’s
output is a square wave, UPAUD, which is used by the Log board to generate the
audio feedback tones that are heard on the speaker.
The serial bus is used by the CPU to communicate with several of the modules
in the instrument. The serial bus is based on either a three wire or seven wire
system. The three wire system is used for modules that only listen (are written
to), while the seven wire system is used for modules that must talk and listen.
Writing to a module begins by latching one bit of data into the Q0 register of
U495 and generating a strobe on the XCLKO-- signal. The strobe is generated by
writing the correct address to U585. The XCLKO-- output (pin 16 of U585) then
goes low for two clock cycles of the CPU (the length of the WR-- pulse). This
strobe is used as a shifting clock to load a single bit into a shift register on all
modules (connected to the DATAO signal).
After all of the data for the intended module has been sent, a 4 bit address,
ADO0 through ADO3, is latched into U495 registers Q4 through Q7. This 4 bit
address is decoded by U590 on the Power Supply Secondaries and becomes the
latch pulse for the intended module latches. The latch pulse is generated by the
LOAD signal (pin 13 of U585) and is two CPU clock cycles long. All modules
must have a pull up resistor on the incoming latch signal in order to guarantee
correct logic levels.
3- 64
2715 Spectrum Analyzer Service Manual
Theory of Operation
Reading from a module begins with the module requesting service through its
active low request signal (FPREQ-- for the front panel, ...). This signal goes into
a priority encoder (U780) on the Power Supply Secondaries, then pulls the
Microprocessor board Interrupt Handler, IRQ1, high. The outputs of the priority
encoder are then used to acknowledge the request for service that activates the
output buffers on the module requesting service. At the same time, the outputs of
the priority encoder, ADI0 through ADI2, are fed into the I/O Subsystem status
register, U595. This status register is then read, due to the interrupt, and the
address of the module requesting service is determined from the ADI0 through
ADI2 lines. Now the process of reading in the data from the module requesting
service can begin.
The lowest bit of the I/O Subsystem status register contains the data from the
module to be read. After each CLKI-- signal, the status register is read and the
data is linked together in a series until all data has been received. The CLKI-signal is generated the same way as the CLKO-- signal described earlier.
Memory
The memory on the Microprocessor board consists of two sections, 128 kilobytes
(16 × 8 kilobytes) of Random Access Memory (RAM), and up to 524 kilobytes
(64 × 8 kilobytes) of Read Only Memory (ROM). The RAM is used for CPU
processing and data space, while the ROM contains all of the system firmware.
Access to the RAM, for either reading or writing, consists of sending out the
address for the byte to be accessed. This address is decoded by U515, and the
appropriate enable line pulled low to select the memory device that is to be
accessed.
Access to the ROM (read only) is performed in the same way as the RAM.
Jumpers (and wires for a more permanent method) are provided on the Microprocessor board for selecting the size of EPROM and RAM memory chips used.
Table 3--16 shows the configuration of jumpers/wires for various size memory
ICs.

Allowances have been made for on board programming of the EPROM devices.
On board programming is done by removing J528 (and/or W528) and then
supplying the appropriate timing and voltage signals to program the EPROMs
through connector J550.
Software Option Jumpers
There are two jumpers (1 kΩ resistors) on the I/O Subsystem Status Register that
can be used by the CPU to set various software options. These jumpers select the
options shown in Table 3--17.
When SW0 is set to 1 (+5 V), all the debug messages will be printed on the
screen. This greatly increases the amount of time needed to complete the power
up sequences.

The programmable interval timer (U580) is an NEC PD71054 (Intel 82C54). It
contains three programmable timers that are used for various functions by the
CPU. The signal GATE_0, from the I/O Subsystem Control Register, is used to
enable (GATE_0 = 1) or disable (GATE_0 = 0) timers zero and one. The signal
AUDEN is used to enable (AUDEN = 1) or disable (AUDEN = 0) timer two.
The signal CLK88 (7.3728 MHz) is fed into timer one. The output of timer 1 is
then fed into timers zero and two. The output of timer zero is then fed into IR0
of the Interrupt Controller. The output of timer two goes to the Log Board to
generate the audio tones.
For programming details, see the NEC PD71054 or Intel 82C54 data sheets.
Frequency Counter
System
The Frequency Counter System consists of buffer amplifiers and three counters.
The three counters are an event counter (28 bits long), the reference/period
counter (29 bits long), and the IF counter (24 bits long).
The event counter consists of devices U290, U480, and counter zero in U470.
The event counter is fed from one of three ports: CFC, DETVID, or OPTION.
These inputs range in frequency from 1 Hz to 40 MHz. The input is selected by
writing the appropriate bits in the Frequency Control Register.
3- 66
2715 Spectrum Analyzer Service Manual
Theory of Operation
The reference/period counter consists of devices U295, U380, and counter one of
U470. The reference counter is fed from the 100 MHz Reference Oscillator.
The IF counter consists of devices U370 and counter two of U470. The IF
counter is fed from the IF input and ranges in frequency from 5 MHz to 15 MHz.
The Frequency Counter Control Register (U385) contains all of the signals
necessary to run and control the Frequency Counters. The following are
descriptions for each of the signals:
H
The TMRGATE signal (bit zero) is used to enable all of the counters in
U470. This signal is active (1) when counting is being performed.
H
The CTR100MH signal is used to enable the 100 MHz buffer amplifier in
the Frequency Counter Buffer Amplifier section.
H
The CLOAD-- signal is used to load counters U370, U380, and U480, with
the data present at the data inputs. This allows the counters to be set to any
starting point.
H
The RESET signal is used to set the counting flip flops (U195) to a known
value.
H
The VID_EN, IF_EN, CFC_EN, and OPT_EN enable the detect video, IF,
CFC, and optional input buffer amplifiers, respectively.
The Buffer Amplifier section consists of an ECL differential line receiver for
each input. The noninverting input of each receiver is connected to the signal
input, while the inverting input is connected to a control signal. The control
signals from the Frequency Counter Control Register are fed into pnp transistors
that act as saturated switches. These switches are then used to enable or disable
the associated receiver. Immediately following the first receiver is a second
receiver to help buffer the signal. The output of the second receiver is fed into a
level shifting transistor that sets the output TTL levels.
On the 100 MHz input, prior to ECL to TTL translation, an ECL flip flop (U195)
is used to synchronize and divide the signal frequency by two.

GPIB, RS- 232, Real Time Clock, NVRAM, and Gated Measurement Functions
The Digital Options module provides both the RS--232 and GPIB interface and
gated sweep capability. The features are:
H
Gated measurement functions to provide in service measurement capability
H
A standard IEEE 488.1 GPIB interface
H
Two RS--232 interfaces which includes:
A full 7 wire interface (RXD,TXD,DTR,DSR,RTS,CTS,CD)
A simple 3 wire (RXD,TXD,DTR) interface
Gated Measurement
Function
H
A real time clock with battery back up
H
NVRAM for storing waveforms and instrument settings
In-service CATV measurements require the ability to look for very weak noise or
distortion components. For example, the C/N measurement will commonly have a
noise floor 50 to 65 dB below the visual carrier (in a 300 kHz resolution bandwidth), and the CSO measurement will have similar amplitudes but in a 30 kHz
resolution bandwidth. Unfortunately, the sidebands resulting from video modulation
of the carrier are generally much stronger that this.
To overcome this measurement difficulty, the analyzer’s data acquisition is shut off
except during quiet scan lines. These quiet scan lines occur during vertical retrace.
The temporary absence of video modulation during these lines means that sidebands
are not present (provided that the resolution filter being used has a settling time
shorter than the horizontal line time). This function is performed by the acquisition
control facility on the Display Storage board.
In practical application the settling time of the resolution filter is not entirely
predictable. The abrupt edges that occur during the horizontal sync pulse immediately preceding a given quiet line shocks the resolution filter into ringing even if it
is tuned some distance away from the visual carrier. To overcome this, the sharp
edges associated with the sync pulse are replaced by soft edges having rise and fall
times of a few microseconds. The shock excitation of the filter is negligible even if
the filter is tuned as close as 500 kHz from the visual carrier. The IF Gate performs
this edge softening function, by blocking the IF path during the sync pulse time.
Instrument Bus Interface
3- 74
The Address Buffering and Decoding section consists of three 74HCT541 bus
receivers (U24, U25, and U26) to receive 20 bits of address and 4 control signals
(BRD_L, BWR_L, BIO/W_L and BCLK), a GAL26V12 (U7) for address decoding
and a 74HCT245 bus transceiver (U1) to buffer the 8 bit data bus. Part of U10 is
also used to generate the bus wait signal BWAIT_L required for TTY write cycles.

Real Time Clock
The Real Time Clock (RTC) is an Oki Semiconductor MSM62X42BRS
clock/calendar (U23). This IC uses an internal 32,768 Hz clock which is divided
down to 1 Hz. This one hertz clock is then used to drive the time registers. Each
time register consists of some multiple of ten of the current time (i.e. 1 sec, 10
seconds, 1 minute, 10 minutes, ..., 10 years). The time registers are also
writeable allowing easy time setting. The data bus for this part is only 4 bits
wide and connected to bits 0 to 3 of the microprocessor data bus. The real time
clock circuitry has a battery backup. Table 3--25 shows the Real Time Clock
functions.

EPROM
The EPROM consists of a single 32 pin socketed 27C200 (U5).
NVRAM
The nonvolatile RAM allows the storage of waveforms and instrument settings.
It consists of a single 128k by 8 CMOS SRAM (U8). Only 96 K of this device is
addressable due to display storage allocations. The battery backup circuit
provides the nonvolatility of this RAM.
2715 Spectrum Analyzer Service Manual

Theory of Operation
Battery Backup Circuit
The battery backup circuits consist of a 2.8 V lithium battery (BT1), and two
DS1210 (U16 and U17) power monitor chips. U17 supplies backup power for
the RAM (U8), likewise U16 supplies the real time clock (U23). The DS1210
chips supply power from the power supply while its voltage is above 4.75 V and
switches to the 3 V battery backup supply when the power supply voltage falls
below 4.75 V. The chip select outputs of the DS1210 chips go high when
switched to battery backup power. This guarantees that the SRAM and RTC will
not be written to during the power down sequence.
RS- 232 Serial Port
The RS--232 ports are implemented by a Z85C30 SCC chip (U22) and an
LT1130A transceiver chip (U9). To read or write to one of the internal registers
of the SCC one must first write to WR0. The data written to WR0 will contain,
in the lower six bits (bits D0 through D5), a pointer to the desired register. The
next read or write cycle then either reads or writes the register that is pointed to
by WR0. At the end of the second read or write cycle the pointer value in WR0
is reset to zero (next write defaults to WR0). Wait states are inserted during
writes due to the timing requirements of the TTY_WR_L signal and the access
recovery time requirements of the Z85C30.
GPIB Interface Port
The GPIB section is composed of the 9914A, GPIB Controller IC (U18), a
75160 GPIB octal bus transceiver (U19), and a 75162 GPIB eight channel
transceiver (U20). In addition there is circuitry included to drive two LEDs.
These two LEDs display the status of the Not Ready For Data (NRFD) and Not
Data Accepted (NDAC) handshaking lines.
The 9914A, as well as the 75160 and 75162, meet the IEEE--488.1 standards.
Access to the 9914A is through the microprocessor address and data buses,
where the lower three bits of the address bus (A0 through A2) determine which
of the thirteen internal registers are to be accessed (6 readable, and 7 writeable).
For GPIB programming information, refer to the 2714 and 2715 Programmer
Manual.
Input Vector Register
3- 76
The entire address space of 0x0e800 to 0x0efff is occupied by this read only
register. In addition to three interrupt status lines, this register also contains other
miscellaneous status. The GPIB_DIR_L status bit indicates the direction of
GPIB data flow. The DONE_PG bit is an output from the Xilinx part which goes
high when self programming is complete. The software must check this bit
before attempting to write to any of the registers on the Xilinx part. If the
DONE_PG does not go high within 500 ms of power up the software should
attempt to reset the system by forcing the BRST_L line low. If DONE_PG still
does not go high within 100 ms, a diagnostic message should be displayed
indicating a hardware failure.

Video Gating Control
Register
There are ten video gating control registers on the Digital Option module. All of
these control registers are write only registers, with the exception of misc. gating
control register (address 0x210). The other nine registers contain line count and
pixel count information used to control the IF gate and Display Storage
acquisition.
IF Gate System
This system performs gating of the IF signal path at a point immediately before
the VR filter. It is composed of two components, the IF Gate itself and a control
signal conditioner.
IF Gate Proper
This section performs the actual gating of 10 MHz IF signals. The desired action
is not to produce abrupt ON/OFF transitions like a switch, however, but rather to
perform controlled, rapid “fades” between ON and OFF. The intent is to
minimize the frequency domain sidelobes arising from the gating of any signals
present in the wide passband preceding the resolution filters. In the CATV test
environment the dominant signal present would most commonly be the visual
carrier of the channel under test, and we want to prevent the gating sidebands
from spoiling our ability to see weak distortion components near the visual
carrier frequency. The gate’s characteristics combined with those of the control
signal conditioner (see Control Signal Conditioner, next) define the transition
times and shapes.
In operation, 10 MHz IF signals entering J2 are converted to differential currents
at the collectors of Q3 and Q4. Note that the asymmetric arrangement of the
network in the emitters of Q3 and Q4 allows use of resistors instead of current
sources with little degradation of balance, taking advantage of the fact that the
base of Q4 is not driven with signal. The overall differential topology of the IF
gate is chosen to minimize even order distortion.
If IF_GATE_EN is held HIGH, Q7A and Q7D steer virtually all the differential
current from Q3 and Q4 through to the emitters of Q2 and Q13. Q2 and Q13
serve as common base stages to keep the large voltage swings at the input of the
transformer T1 off the collectors of Q7A and Q7D, which have large, nonlinear,
capacitances. This is to reduce distortion (particularly odd order terms) and to
improve the output circuit bandwidth.
If IF_GATE_EN is held LOW, the differential signal current is steered into Q1
and Q14 via Q7B and Q7C. The outputs of Q1 and Q14 are damped into
resistors R1 and R2.
During transitions, which are governed by the linear ramp waveform applied to
the bases of Q7B and Q7C, the differential signal current steered to the output is
modulated according to the transfer function of a bipolar transistor differential
amplifier having no emitter degeneration. The resulting soft envelope rise and
fall shapes provide a rapid fall off of sidebands with frequency offset from the
visual carrier.
2715 Spectrum Analyzer Service Manual
3- 77
Theory of Operation
Control Signal Conditioner
This circuit takes in HCMOS logic levels and produces shaped and risetime
controlled control signal(s) having the characteristics required by the IF gate
circuit. The IF_GATE_EN signal is first passed through CMOS inverter U6
powered from a locally regulated +5 V source to produce output voltage levels
which are well defined, stable, and noise free. The circuit comprising Q5, Q6,
Q8, Q11, and Q12 is a crude operational amplifier with a well defined, intentionally low slew rate. Its purpose is to convert the abrupt logic level transitions into
linear ramps having controlled rise and fall times. R27, R33, R37, and R44
provide scaling and offset to this signal to provide the correct drive waveform to
the steering circuit that makes up the IF gate proper.
Video Demodulator
The primary purpose of the video demodulator is to produce TV sync pulses
derived from video modulation on the 110 MHz IF signal. These pulses are used
by other circuitry to control the timing of the IF gate and so forth. It is necessary
that the sync pulses be available whenever the spectrum analyzer is tuned
anywhere within the selected TV channel. A secondary function of this module
is to pass on a slightly amplified sample of the 110 MHz IF signal to the FM
(satellite) TV demodulator located on the sweep board.
Operation of the video demodulator board is described as follows:
110 MHz to 45.7 MHz
Downconverter
Input IF signals near 110 MHz are amplified by about 13 dB in U3, then applied
to a splitter, one output of which relays most of the signal to the satellite TV
demodulator. The signal from the other output is loosely bandpass filtered by L2,
C5, and C8, then sent through a 2nd gain stage (U5) (whose function is primarily
to provide reverse isolation) to a highpass filter with a cut--on frequency of about
104 MHz. Output from this filter is then applied to a downconverter (U4) which
converts the signal to 45.7 MHz (visual carrier) without further frequency
inversion (the 110 MHz IF signal is already frequency inverted from the
spectrum analyzer input). The 45.7 MHz signal then passes through a SAW
(surface acoustic wave) filter which imposes final bandpass limiting and
provides the Nyquist slope for correct detection of vestigial sideband TV signals
by the subsequent detector IC.
Local oscillator for the downconverter is generated by an internal VCO whose
frequency is maintained in part by an AFC loop whose error signal comes from
the video detector IC. This AFC loop is used to keep the mixer output frequency
at 45.7 MHz while the input frequency ranges from 108.5 to 114.5 MHz as a
function of the spectrum analyzer’s center frequency setting. The VCO is tuned
by a dual varactor (CR2) which resonates with L5. One part of this varactor
receives a programmed tuning voltage from a DAC (U6) which is set by the
instrument’s firmware according to the frequency difference between the visual
carrier and the instrument’s center frequency setting. The other part receives the
AFC error voltage if AFC is ON; otherwise, it receives a fixed midrange voltage.
3- 78
2715 Spectrum Analyzer Service Manual
Theory of Operation
The tuning voltage path from the DAC to its varactor includes a temperature
correction from sensor (U9).
Video Detector
The 45.7 MHz signal from the SAW filter is presented to the MC44301
demodulator (U16). This device passes the signal through an AGC controlled IF
amplifier, then to a synchronous detector. The reference signal for the detector
comes from an internal PLL. Note that the oscillator for the PLL actually runs at
half frequency, and its output is frequency doubled on--chip for use by both the
PLL’s phase detector and the synchronous video detector. This reduces stray
coupling between the oscillator’s external resonator (C41, C42, and L11) and the
IF input to the chip. The AFC error signal is a current from pin 5, and the video
output is a voltage (offset several volts positive) at pin 2. The video output is
passed through a single pole RC lowpass filter to strip off most of the color burst
signal, then through an emitter follower (Q10) on to the sync separator (U15).
The emitter follower is used because the input pin of the sync separator uses an
active diode clamp DC restorer which prefers being driven from a low impedance source. The lowpass filter also includes a video attenuator to properly
match the video amplitude to the sync slice level of the sync separator. A video
test pad is provided at the output terminal of the demodulator IC.
The control line SECAM_EN is provided to reconfigure the demodulator for
positive modulated signals. When SECAM_EN is taken high, two actions occur.
First, Q9 turns on, which changes the operating mode of the demodulator IC.
Secondly, part of U8 selects AGC sense gate timing control from the back porch
output of the sync separator because the sync tip is not a viable place to sample
the video for AGC with positive modulation.
Sync Separator
This section uses an LM1881 IC (U15) to produce composite sync, vertical sync,
and Even/Odd field flag signals (all at 5 V logic levels) from the demodulated
video. A non--retriggerable one--shot multivibrator (U12) in the horizontal sync
path serves to strip out the unwanted equalizing pulses during the vertical retrace
interval so that the resulting horizontal sync signal is a simple periodic pulse
train at the horizontal rate. This one--shot is set up for a time interval of about
3/4 of the horizontal sweep period, and the feedback path from the “Q” output to
the “A” input serves to block triggering until timeout occurs, thus preventing
triggering by the equalizing pulses. If this process starts up out of sync, correct
sync is automatically re--established within one scan line of when the equalizing
pulses end. The horizontal sync, vertical sync, and Even/Odd flag signals are
buffered by U2 and sent to the Digital Options board as H_SYNC, V_SYNC,
and E/O_L respectively to drive the instrument’s gate timing circuits.

Theory of Operation
AFC Lock Control
Circuitry
The lock control circuitry is used to switch the AFC loop (mentioned in the
downconverter description) ON or OFF as required in the course of getting the
video demodulator locked onto a new TV channel. The AFC loop needs to be
reset by the instrument firmware on certain occasions (such as instrument
re--tuning) to assure that the demodulator is locked to the correct channel.
The locking procedure, carried out by the instrument’s firmware, is to first tune the
spectrum analyzer to the desired center frequency. Then, the microprocessor applies
a nominally correct tuning voltage to one half of CR2 by sending an appropriate
setting to the DAC. At this point the demodulator may still be locked to the wrong
thing (if so, usually the adjacent channel’s sound carrier), so the final step in the
procedure is to momentarily disable the AFC by switching the AFC tuning line to a
midrange value (done by part of U8). When this is done, the demodulator IC will
re--lock to the correct video carrier, although the IF frequency will still be off by as
much as a few hundred kHz due to drift and tolerances. After a brief delay the
microprocessor re--enables the AFC, which restores the frequency offset to virtually
zero. At this point, valid sync pulses are available from the video demodulator
system.
The tuning DAC setting used is calculated from: dac_val = 165 -- 20.44 * freq_diff.
The dac_val ranges from 0 through 255, and the freq_diff is the difference in MHz
between the instrument’s frequency setting and that channel’s visual carrier
frequency. For example, if the instrument is to measure the CSO component at
1.25 MHz above the visual carrier, the correct dac_val is 139.
Sweep
A Miller integrator, U270, is the core of the sweep generator. With a logic low at pin
16 of the analog switch U260B, the switch is closed. All of the timing current from
pin 3 of U170 then flows through the switch, and the voltage across the switch is
nearly 0 V. Thus, the sweep voltage is approximately the same as the voltage at pin 3
of U270 ⟨≈+1.3 V). When the sweep logic circuit, U460, receives the proper signal,
pin 19 goes to a high state and the switch (U260B) opens. All of the timing current
is then steered to the timing capacitors, and they begin to charge. Operational
amplifier U270 maintains a 0 V difference between its input pins 2 and 3 by
changing its output voltage to provide the displacement current to the timing
capacitors. Since the capacitor charges linearly, the resultant output at pin 6 of U270
appears to decrease linearly. Thus, the sweep is generated.
The sweep continues to decrease until the voltage at pin 9 of U470B is less than the
voltage at pin 10 (of U470B). At that time, the output of U470B goes to a low state
and clears the sweep gate flip flop inside U460, and a retrace cycle is initiated. The
sweep logic circuit, U460, sets pin 16 of U260B low, closing the analog switch. The
timing current is diverted from the timing capacitors, and the capacitors begin to
discharge. The resultant sweep voltage starts to rise. When sweep voltage discharges
to within 28 mV of its final value, the output of U540B goes to a high state. This
releases holdoff capacitors C253 and C252. One of these begins to charge.
3- 80
2715 Spectrum Analyzer Service Manual
Theory of Operation
When this voltage reaches approximately 1 V, an RS flip flop inside U460 resets and
the holdoff cycle is finished. The sweep gate logic circuit is then enabled to accept
another trigger and, if in the free run mode, another sweep is then started.
Transistor Q574 is used to abort the sweep and initiate another holdoff.
Transistor Q255 is used to choose a long or short holdoff time. A logic 1 at
pin 13 of U312 turns on the transistor, diverting the available current to charge
C252. This has the effect of making the holdoff capacitor look larger.
Multiplexer U170 is used to determine the timing current to be used while U160
chooses the timing capacitor.
The trigger signal is selected by multiplexer U452. The output on pin 3 (TRIG)
goes to the input of comparator U470A. This is wired as a Schmitt trigger with
the threshold set by the voltage appearing at pin 4 of U470A. This threshold
voltage is always positive regardless of the value of TLVL. The circuit composed
of CR373 and U374B provides an absolute value generator. When the value of
TLVL is negative, operational amplifier U374B is in equilibrium and the output
is positive. When the value of TLVL is positive, the output of U374B goes as far
negative as possible, effectively turning off CR373 (the operational amplifier is
open loop). With CR373 off, the value of TLVL appears at pin 4 of U470A.
When U374B is open loop, Q351 is turned on and pin 3 of U460 goes to a
logic 0. This is the slope input that is EXCLUSIVE ORed with the trigger input
at pin 2. Thus, the opposite slope is selected.
When TLVL is not being used to set the trigger level of the sweep, it can be used
for the manual scan as these two functions are entirely mutually exclusive.
During a manual scan, pin 7 of sweep logic IC U460 is set low. This sets the
sweep gate flip flop in U460. Also, multiplexer U160 is set to select R162, the
100 kΩ resistor. Multiplexer U170 is set to select current input from R175 that
ultimately originates at TLVL. Miller integrator U270 is then used as an
amplifier and the output voltage is then proportional to the value of TLVL.
The source for the continuous TV line trigger and TV field trigger is from the
sync separator, U320. This chip provides a vertical interval and composite sync.
The composite sync contains the elements of the equalization pulses that occur
during the vertical interval. This composite sync is fed to the two monostable
multivibrators that are used to strip off the double pulses that occur during the
vertical interval. One of the timers, U225A, is set for a pulse width of 3/4 of a
horizontal scan. This output is used to inhibit another trigger from occurring on
either monostable multivibrator until it has timed out. The other timer, U225B,
provides an approximately 10 s pulse that is used as a general horizontal
blanking pulse (HCLK).
Composite video source for the sync separator is from the output of operational
amplifiers U244 ( for positive sync) or U343 (for negative sync). U244 also
forms the source of the internal trigger.
2715 Spectrum Analyzer Service Manual
3- 81
Theory of Operation
The video monitor mode is generated by using the vertical sync outputs of the
sync separator and HCLK to control an auxiliary sweep generator formed by
U560B and its associated components. This ramp generator (U560B) provides
the vertical sweep while the normal sweep circuit forms the horizontal sweep.
When the video monitor mode is selected, Q522 is turned off, which lowers the
sweep current, and slows the normal 5 s/div sweep to approximately 6.3 s/div.
This has the effect of stretching out the TV picture over the entire length of the
screen. When a vertical scan is nearly complete, the output of comparator U540A
goes high, and on the next HCLK the signal at pin 14 of U670 goes high. At this
time, Q664 turns on Q663 and the vertical sweep capacitors C564 and C563 are
discharged. This resets the vertical sweep to 0 V, which corresponds to the top of
the screen. The signal VLVL is used to speed up or slow down the vertical sweep
to allow the vertical interval to be observed in detail and to allow for various
vertical scan rates. When the video monitor is enabled, the Z axis signal is
selected through analog switches U443A or U443D, depending on the desired
polarity.
The video monitor mode has two input sources. First, in the AM mode, the input
source is from the video amplifiers located on the Log board. Second, in the FM
(satellite) mode, the video source is from the FM demodulator (U770 on the
Sweep board). The input of the FM demodulator is from amplifier U760, which
provides approximately 16 dB of gain. The input to the board (to U760) is
picked off just prior to the 110 MHz bandpass filter, located on the RF Mother
board. The output of the FM demodulator is then fed to operational amplifier
U690, which inverts the signal and adds an offset. Analog switches U260A and
U260C are used to select between broadcast (AM) video and satellite (FM)
video.
The selective line trigger is selected by programming a line number in the
counter made up of U510, U620, and U630. This counter is then decremented by
HCLK. When the counter is at a minimum count (0), the signal at pin 15 of
U630 goes to a low state. This signal is then delayed for one HCLK to remove
any glitches that would produce a false trigger. The delayed terminal count
appears at pin 17 (HTRIG) of U670. This signal is used to trigger the sweep. The
line trigger counter is preset during field one by the signal at pin 7 of U670. This
preset signal is generated in U670 by sensing whether timer U225A has timed
out at the beginning of the vertical interval. The vertical output of U320 always
starts at the beginning of the major serration during the vertical interval. This
serration starts just prior to an HCLK during one field. During the next field, the
serration starts on an equalization pulse halfway between HCLK. This difference
is used to determine the odd/even field. When the odd/even field flip flop inside
U670 switches to the high state, a positive edge transition detector generates the
preset enable signal for the line counter. The proper number to preset the counter
with is determined by adding an offset of 6 for NTSC and 3 for PAL.
The graticule lights are controlled by switching Q707 on, which then turns on
Q706.

All of the control information is shifted in through four shift registers U211,

Front Panel
The Front Panel acts as an interface between the user and the instrument. These
circuits translate operator actions on front panel controls into data for the microprocessor to read and execute. The Microprocessor outputs data showing current

Input Shift Registers
The Input Shift Registers consist of three serial input, parallel output shift registers
cascaded together. The outputs of the shift registers drive the front panel LEDs and
provide two control signals. The LEDs are connected from the +5 V supply to the
shift register output through a 274 Ω resistor. The nominal LED current is 10 mA.
This current is high enough to provide adequate light for the LED to be seen in direct
sunlight. A low (zero) is required on the output of the shift register to light the LED.
Two control signals are provided on the shift register outputs. They are the front
panel request enable (FPREQEN--) and the clock in enable (CLKIEN--). Both of
these signals are active low.
2715 Spectrum Analyzer Service Manual
3- 83
Theory of Operation
The FPREQEN-- signal is used to enable the front panel request output buffer. If
FPREQEN-- is in the inactive state, the front panel service request line to the
microprocessor will always be active (always requesting service).
The CLKIEN-- signal is reserved for future use.
Switch Matrix
The Switch Matrix consists of 59 normally open single pole, single throw
switches. These switches are configured in a 6 × 11 matrix (possibility of 66
switches total). By using this matrix, it is possible to determine the location of a
closed switch by looking at the rows and columns of the matrix.
Each column in the matrix is held low by a 100 kΩ resistor to ground, while the
rows are connected to the +5 V supply through a 22.1 kΩ resistor and to the base
of an open collector transistor. When all the switches are open, the transistor is in
the off state, thus the row line is low (ground). When a switch is closed, the base
of the transistor is pulled down to approximately 4.3 V and the transistor turns
on, thus pulling the row line to the +5 V supply. At the same time, the column
line is pulled high due to the resistor divider on the base of the transistor.
The row and column lines are fed to inputs of three parallel to serial shift
registers. In addition to the shift registers, the row lines are wired to form a
phantom OR gate whose output triggers a debounce circuit.
Switch Matrix Debounce Circuit. The debounce circuitry for the switch matrix
consists of three retriggerable single shots. Two of these single shots are used to
establish the minimum time between key presses. The third single shot is used to
debounce the switch being pressed.
The two single shots used to establish the minimum time between key presses
operate as follows:
The row lines of the switch matrix are wired to form a phantom OR gate whose
output drives the trigger inputs of both single shots. Each single shot triggers on
the opposite edge of the other. The rising edge triggered single shot is called the
Press One Shot (POS), while the falling edge triggered single shot is called the
Release One Shot (ROS).
For a typical key press, the one shots will operate as follows:
1. The key is pressed and a rising edge is presented to both the POS and the
ROS.
2. The POS is triggered and its output goes active.
3. Due to the bouncing of the switch, a negative edge is presented to both the
POS and ROS.
4. The ROS is triggered by this edge and its output becomes active.
3- 84
2715 Spectrum Analyzer Service Manual
Theory of Operation
5. Steps 2 and 4 are repeated, retriggering either the POS or ROS, until the
switch has stabilized in the closed position.
6. Each single shot then times out approximately 50 ms after the last valid
trigger.
7. Now the switch is released and a negative edge is presented to both the POS
and the ROS.
8. This edge triggers the ROS and its output becomes active.
9. With the ROS output active and POS output inactive, the POS is held in the
reset state by a NAND gate.
10. The ROS is retriggered, by each falling edge of the bouncing switch, until
the switch has stabilized in the open state.
11. After approximately 50 ms, the ROS times out and its output becomes
inactive.
12. The POS and the ROS are ready for another key press.
Figure 3--27 shows the three possible scenarios of key presses and how the
debounce circuit reacts to each one.

Theory of Operation
The three conditions illustrated in Figure 3--27 are as follows:
1. Switch pressed and released inside the 50 ms time of POS.
2. Switch pressed and released well after both the POS and ROS have timed
out.
3. Switch pressed and released with the POS becoming inactive during the
release.
The debounce single shot is triggered by the rising edge of the POS and has a
1 ms pulse width. At the end of the 1 ms pulse, the following two conditions
occur:
Gray Code Knob
H
The status of the switch matrix is stored in the output shift registers (U130,
U140, and U319).
H
The service request circuit on the Front Panel board is activated.
The gray code knob is a rotary knob that outputs a two bit gray coded pulse train.
The direction of the knob is decoded by monitoring the two output lines of the
knob. The two knob outputs drive a NAND gate whose output is used to trigger
a single shot. The single shot is positive edge triggered. Triggering the single
shot in this method gives a pulse to the Service Request/Acknowledge circuit as
the knob leaves the position of both bits high. The direction of the knob can be
determined by loading the status of the knob just after the both bits high
position.
Two open collector transistors on the knob outputs are used to set the correct
TTL levels. In addition, two Schmitt trigger inverters are used to buffer the
transistor outputs and speed up the edge transitions.
Service
Request/Acknowledge
Circuit
The Service Request/Acknowledge circuitry consists of two flip flops (request
for service flip flop) that request service from the firmware. A description of a
typical request for service and firmware acknowledgment follows:
1. A key is pressed on the front panel and the output of the Press One Shot goes
high.
2. The rising edge on the Press One Shot output triggers the debounce single
shot. The falling edge of this pulse loads the switch matrix status and clocks
the first flip flop.
3. The output of the first flip flop then sets the request for service flip flop,
making the FPREQ signal low (active).
4. The output of the request for service flip flop is then used to reset the load
flip flop, thus completing a load pulse for the shift registers.
3- 86
2715 Spectrum Analyzer Service Manual
Theory of Operation
5. After the firmware recognizes the request for service, the FPACK-- line is set
low, which enables the DATAI and CLKI tristate buffers.
6. The data is then clocked out of the switch matrix shift registers.
7. After the data has been clocked out, the FPACK-- line is set high, disabling
the DATAI and CLKI tristate buffers.
8. The rising edge of FPACK-- is also used to reset the request for service flip
flop.
9. The board is now ready for another key press.
Diagnostics and
Testability
There are two diagnostic tools available for the front panel, the key test and the
LED test. These diagnostic tools reside in instrument firmware. They are used
during initial board turn on and when the front panel needs repair. Descriptions
for these diagnostic tools follow.
Key Test. The key test is located in the extended diagnostics menu of the
instrument and consists of text prompting the technician on which key to press.
If the correct key is pressed, its location in the switch matrix and the next switch
to be pressed are displayed. If the incorrect key is pressed, the speaker beeps, and
the same key press is prompted again. Up to four incorrect key presses are
allowed before the firmware continues on to the next key.
LED Test. The LED test is also located in the extended diagnostics menu of the
instrument and uses the knob to light each LED one at a time, in a known
sequence. By rotating the knob, each LED is lit. The test runs until the backspace
key is pressed.
Power Supply (Primary and Secondary)
The Power Supply operates with a line input voltage from 90 VAC to 250 VAC
without range switching. This is done by regulating the rectified AC input
(125 V to 350 V) to 60 VDC.
An inverter drives a transformer having numerous secondaries, including a high
voltage winding (1400 V peak) for the CRT supplies. The secondary voltages are
rectified to provide operating power for the instrument.
The high current secondary output, +5 V, is regulated by feedback to the primary
pulse width modulator. The other secondary outputs track +5 V fairly closely,
except for the high voltage supplies, which have secondary regulation.
The Power Supply circuits are divided into the primary circuits and the
secondary circuits.
2715 Spectrum Analyzer Service Manual
3- 87
Theory of Operation
Primary
The Power Supply primary circuits consist of the AC Input circuit, a Pulse Width
Modulator (PWM), an Inverter, and a Frequency Lock circuit. See Figure 3--28.
AC Input. Input power is applied through an EMI line filter, a line fuse, an on/off
switch, additional EMI filtering, and a full wave rectifier and storage capacitor.
The line filter prevents power line interference from entering the Power Supply
and also attenuates internally generated signals radiating out the power cord. The
additional EMI filtering attenuates harmonic noise generated in the PWM and
conducted out the power cord. Additional EMI filtering consists of a common
mode choke, line to line capacitors, and line to ground capacitors.
A thermistor, having a negative temperature coefficient, limits current surge at
power up. The surge current drops within several cycles of line input as the
storage capacitor charges. When power is applied, the thermistor limits the line
current until it has had time to warm up. As the line input current heats the
thermistor, the increase in temperature decreases the resistance value of the
thermistor, reducing power loss across the thermistor.
The AC line signal is coupled to the secondary through T110 and is also used in
the trigger circuits as a line trigger source.

PWM Integrated circuit U280, a multifunction PWM IC, is used to drive a
MOSFET switch. The PWM, operating in a single ended mode, sets frequency,
regulates voltage using its internal +5 V reference, allows current limiting, and
provides a slow start up.
3- 88
2715 Spectrum Analyzer Service Manual
Theory of Operation
At power up, there is a delay until R185 charges C290 to approximately 20 V, at
which time Q690 and Q691 turn on to supply power to the PWM IC. The capacitor
provides drive current until the PWM output (TP293) reaches 60 V relative to
special ground (TP190).
Initial pulses to the MOSFET switch are narrow, but they gradually widen as C691
(between pins 4 and 14 of the PWM IC) charges. If current through R260 at the
source terminal of the MOSFET switch exceeds 1.9 A, the pulse width is limited
until C163 at the primary center tap of the power transformer charges up to the
desired voltage. The PWM operates in a voltage control mode set by the string
R693, R682, R685, and R686, where the output voltage across C163 is compared
to the PWM’s internal +5 V reference. The negative end of the +5 V reference is
connected to TP293 (60 V above special ground). Frequency is set by C690 and
R694 in parallel with R681 and R680. Pin 10 of the PWM conducts through
CR680 and R672 to Q270 (a MOSFET switch) for fast positive transitions.
Transistor Q680 turns on for fast negative transitions. Series RC damping networks
R696/C692 and R684/C681 compensate the PWM transient response.
The MOSFET duty factor is approximately Eo/Ein. This will be approximately 16%
(2.2 s) at 250 V line input. The PWM IC has a maximum duty factor of 95%,
which means that voltage Ein across storage capacitor C171 can drop to approximately 70 V before loss of regulation occurs.
Three components carry high current. These are MOSFET Q270, commutating
diode CR270, and coupled winding energy storage inductor (transformer) T190.
Capacitor C280 between the storage inductor windings compensates for leakage
inductance. The transformer has two auxiliary windings. One winding, pins 6 and
7, has a positive peak of 20 V and provides current for the PWM through 6.2 V
Zener diode VR690 and CR290. The other winding, pins 9 and 10, drives out of
phase current through a small capacitor connected to the chassis. This reduces line
conducted EMI by cancelling current flowing through stray capacitance to chassis
from the drain of Q270 and other parts connected to the same node.
Current into C163 at the center tap of the power transformer is continuous, as in a
Buck regulator. The current in the storage inductor ramps up when Q270 is on and
ramps down when CR270 conducts. Since there is current and stored charge in the
diode when Q270 turns on, L170 is included in the loop to limit current and reduce
power losses. Energy stored in L170 is recovered with three diodes and a capacitor
and transferred to the output.
Inverter. The inverter consists primarily of a PWM IC, a pair of MOSFETs, and the
power transformer. The MOSFETs are driven in push pull mode by U260, the
PWM IC. There is no regulation to modulate the pulse width of the drive signals.
Current flows through the power transformer from the center tap to the closed
MOSFET switch. The operating frequency is approximately 26 kHz as set by R664
and C661. Supply current for U260 is through R261 clamped to 12.4 V by
VR660 and VR661.
2715 Spectrum Analyzer Service Manual
3- 89
Theory of Operation
NOTE. For instruments with serial numbers B030000 or above, a dead time
control (DTC) R669 has been added which will be used to set the maximum high
voltage measured at the –2.75KV test point by varying the voltage at pin 1 of
U260. New values for C262 and R652 have been chosen to lower the effect of the
leakage current from pin 4 of U260. Any pin 4 leakage current through R652 will
reduce Power Supply performance. Supply regulation for U260 has been
improved by lowering the resistance of R261.
The low impedance, fast switching of the MOSFETs is slowed down by series
inductors L241 and L250. As each MOSFET turns on, the drain inductor,
transformer leakage inductance, and transformer reflected capacitance resonate.
This is damped by CR740, CR640, and R240. Also, when each MOSFET turns
on, CR250, CR260, C151, and R152 limit the peak voltage excursion to
approximately 120 V. The series resistor capacitor (RC) networks across the
inductors absorb some energy in both conditions.
Frequency Lock. The inverter frequency is approximately 26 kHz and the
pre--regulator operates at 3 times this rate. The D flip flop U670A is clocked at
78 kHz with the D input driven at 26 kHz through clamp diode CR661. The
Q output is RC filtered and modulates pin 6 of the PWM IC to maintain the
3:1 frequency ratio. When R680 is adjusted for lock, one sample of the D input
is low, the second is high, and the third is at the edge of the 26 kHz waveform.
When the third sample is high, the filtered output to the PWM will reduce its
frequency, and increase the frequency when low. This lock prevents low
frequency IM between the two frequencies that could be audible. The lock can
occur at various ratios with 3:1 chosen so the predominant harmonic of the
inverter coincides with the PWM fundamental.
Secondary
The +5 V potentiometer, R937, is used to adjust +5 V1, the reference voltage.
This reference voltage is compared with the +5 V supply by U630B, and an error
voltage is generated. Feedback through the optoisolator U281 controls the pulse
width of U280 on the primary side. The center tap voltage on the primary side of
the power transformer is adjusted this way to correct small changes in +5 V.
Other secondary DC voltages are determined by transformer winding ratios and
degree of loading. Three secondary windings (5 V, 10 V, and 50 V) have series
RC damping networks to circulate energy stored in the power transformer
leakage inductances.Choke/capacitor (lc) filter networks at the output of each
rectifier reduce ripple to acceptable levels for instrument power.
Most of the available power flows to the +5 V, +10 V, and --11 V supplies. The
+20 V supply is lightly loaded and generated by voltage doubling. The fan
supply is --11 V. The +50 V and +115 V supplies are used for Z axis control,
CRT adjustments, and deflection amplifiers. The --5 V1 is a stable supply
generated by a three terminal regulator for use in the deflection amplifiers.
Secondary regulation is provided for the high voltage supplies. U630A and Q130
control the peak to peak amplitude of the high voltage AC voltage seen by both
cathode and anode rectifiers. Constant output and post deflection anode ratio is
maintained as internal loading varies. This keeps the display fixed in size.

The voltage multiplier is encapsulated in high insulation material. Both cathode
and anode multipliers are AC coupled within the multiplier and have multiplication factors of --2 and +8, respectively.
The high voltage regulator circuit takes a sample voltage from the cathode and
controls the impedance of Q130 for a steady cathode voltage. The parallel
combination of C130 and Q130 (with R637) is switched into the high voltage
current loop when the voltage at pin 23 of T230 goes negative (CR531 turns off
and CR530 turns on). The positive DC voltage on C130 is added to the negative
excursion on the high voltage winding. Therefore, the total peak to peak voltage
seen at the input of the high voltage multiplier is the peak to peak voltage at the
transformer secondary minus the DC charge on C130. The high voltage outputs
are changed by varying the impedance of Q130, which discharges C130. VR530
and VR630 provide a 300 V clamp that protects C130, Q130, CR530, and
CR531 from overvoltage. The cathode has almost 300 V of regulation range.
NOTE. In instruments with serial numbers B030000 or above, C130, CR530,
CR531, Q130, VR530, and VR630 were changed to extend the cathode regulation range to nearly 400V. Voltage regulators VR530 and VR630 provide a 460 V
clamp.
Vertical Display
The Vertical Display circuit is a video amplifier (preamplifier and a paraphase
amplifier). Gain and DC offset (Vertical Position) are set so the signal at the
input of the paraphase amplifier swings from --0.7 V to +0.7 V for a full screen
signal. The output of the paraphase amplifier then drives the vertical deflection
plates.
Three signals may be applied to the Vertical Display circuitry:

H
LOGVID (Detected video from the Log board)
H
DSVER (from the Display Storage board)
H
VIDVERT (Vertical Scan signal from the Sweep board)
2715 Spectrum Analyzer Service Manual
Theory of Operation
Horizontal Display
The Horizontal Display circuit is a paraphase amplifier. Gain and DC offset
(Horizontal Position) are set so the signal at the input of the paraphase amplifier
swings from --1 V to +1 V. The output of the paraphase amplifier then drives the
horizontal deflection plates.
Two signals may be applied to the Horizontal Display circuitry:
H
SWP (Sweep from the Sweep board)
H
DSHOR (from the Display Storage board)
When an active signal is displayed in normal mode, the horizontal drive signal is
the sweep (SWP), and the vertical drive signal is the detected video (LOGVID);
when a stored signal is displayed, the horizontal drive signal becomes DSHOR
from the Display Storage board, and the vertical drive signal becomes DSVER
from the Display Storage board.
When the video monitor mode is enabled, the vertical signal is a vertical scan
signal (VIDVERT) and LOGVID and DSVER are switched out. At the same
time DSHOR is also switched out, and the sweep signal (SWP) is set to a TV
line rate. A third signal, VIDZ (live video), is routed to the Z Axis circuit.
Z Axis
The Z Axis circuits receive signals from the Display Storage and Sweep boards
and accept control levels from the front panel INTENSITY control. These
signals are then used to control the CRT beam brightness by modifying the CRT
control grid voltage.
VIDZ from the sweep board and /CRTINTS from the Front Panel are summed
into the Z Axis drive amplifier. Two gates also drive the amplifier: /DSBLANK
during readout display periods and SWPGATE during sweep display periods.
The Z Axis clipper circuit consists of two series diodes, plus associated
components. The voltage that passes the clipper circuit is coupled through a
capacitor to the Z Axis rectifier.
The clipped Z Axis drive signal is rectified by a pair of diodes. The rectified
voltage is then fed to the grid of the CRT. A capacitor couples fast changes of the
drive voltage to the grid to speed up the response of the grid circuit. The CRT
grid is protected from high voltage arcs by a spark gap (E110). Also, a 4.75 kΩ
resistor at the junction of the clipper diodes protects the rectifier diodes from
high voltage surges in case the CRT arcs. Clamp diodes CR200 and CR201
protect the Z Axis amplifier from high voltage transients.

Performance Verification
This section contains procedures for verifying that the instrument performs
according to the characteristics stated in the Performance Requirement columns
in Section 1: Specifications.
If a failure is found, it is recommended that only those circuits that do not meet
performance criteria be adjusted. If adjustment fails to return the circuit to
specified performance, refer to Section 6: Maintenance for repair procedures.
A procedure that is unique to instrument options is described as a subpart of the
step, where practical, or at the end of this section.
Incoming Inspection Test
The User manual contains a system checkout (power up check) of the Spectrum
Analyzer. This check is recommended for incoming inspections because it
requires no external equipment or special experience and is a reliable indication
that the instrument is performing properly.
Verification of Tolerance Values
Tests shall be performed only after the normalizations have occurred. If a test
should fail, normalize the instrument by pressing UTIL 3 0. The normalization
will correct for any changes in the operating environment due to time or
temperature.
Measurement tolerance of test equipment should be negligible in comparison to
the specification being tested. If not, the error of the measuring apparatus must
be added to the specification tolerance.
History Information
Corrections or additional information is included when revisions are made to the
manual. If modifications require changes in the procedures, information applicable
to earlier instruments will be included within a step or as a subpart to a step.

Adjustment Procedures
If the instrument performance is not within tolerance for a particular characteristic, determine the cause, repair if necessary, then use the appropriate adjustment
procedure to return the instrument operation to performance specification. After
any adjustment, verify performance by repeating the applicable part of the
Performance Verification procedure.
Allow the instrument to warm up for at least 15 minutes, in an ambient
temperature of 20° C to 30° C before making any adjustments. Waveform
illustrations in the adjustment procedure are typical and may differ from one
instrument to another. These waveforms should not be construed as being
representative of specification tolerances.
Static Discharge Precautions
Static discharge can damage many semiconductor components used in this
instrument.
Many semiconductor components, especially MOS types, can be damaged by
static discharge. Damage may not be catastrophic and, therefore, not immediately
apparent. It usually appears as a degradation of the semiconductor characteristics.
Devices that are particularly susceptible are: MOS, CMOS, JFETs, and high
impedance operational amplifiers (FET input stages.) The damaged parts may
operate within acceptable limits over a short period, but their reliability will have
been severely impaired. Damage can be significantly reduced by observing the
following precautions.
H
Handle static sensitive components or circuit assemblies at or on a staticfree
surface. Work station areas should contain a staticfree bench cover or work
plane such as conductive polyethylene sheeting and a grounding wrist strap.
The work plane should be connected to earth ground.
H
All test equipment, accessories, and soldering tools should be connected to
earth ground.
H
Minimize handling by keeping the components in their original containers
until ready for use. Minimize the removal and installation of semiconductors
from their circuit boards.
H
Hold the IC devices by the body rather than the terminals.
H
Use containers made of conductive material or filled with conductive
material for storage and transportation. Avoid using ordinary plastic
containers. Any static sensitive part or assembly (circuit board) that is to be
returned to Tektronix, Inc. should be packaged in its original container or
one with antistatic packaging material.

Test equipment required:
Voltage Variable Isolation Transformer
Test Oscilloscope with Probes
Multimeter (DMM)
High Voltage Probe (X1000)
WARNING. Use an isolation transformer when working on the Power Supply.
The transformer must have a three wire input and output connector with ground
through the input and output. Stancor GIS21000 is an example of a suitable
transformer.
Hazardous line potential exists on the Power Supply board at all times the
instrument power cord is connected. If it becomes necessary to remove the shield
on the bottom of the Power Supply board, use extreme caution when handling
the instrument.
Refer to Figure 5--1 for the location of most adjustments and test points.
1. Connect an Isolation Transformer in line with the Spectrum Analyzer power
input and the AC line voltage source of 90 to 250 VAC.
2. Apply power to the Spectrum Analyzer and turn on the graticule lights
(DSPL 6).
3. Adjust R937 (+5 V ADJ) on the Power Supply board for +5.0 VDC at the

5. Place the Channel 2 probe near R680 on the Power Supply board. The test
oscilloscope should display approximately four periods of the waveform at
TP250.
6. Adjust R680 (LOCK) so that the waveform on TP270 is locked to the
waveform on TP250. An unlocked waveform exhibits a noticeable amount of
jitter. When the waveform locks, a sudden shift of the waveform occurs and
the jitter goes away. Continue adjusting R680 counterclockwise until lock is
lost or the potentiometer is fully counterclockwise. Make a note of the range
through which the signal stays locked. Center R680 in the noted range.
NOTE. The waveform at TP270 has phase jitter due to pulse width modulation.
7. Vary the line voltage from 90 VAC to 240 VAC while checking for no loss of
lock. Readjust R680 if lock is lost. Reset the line voltage to nominal line
voltage.
8. Enable the checkerboard pattern by pressing UTIL 5 2 2 and set INTENSITY fully clockwise.
9. Set R703 (Z AXIS) on the Power Supply board fully counterclockwise.

Connections to Test
Instrument
Use the following procedure to connect the PC to the instrument.
1. Connect the signal generator and power meter to the computer through GPIB
cables. Connect the instrument to be tested to the computer through a GPIB
or RS--232 cable. See the 2714 & 2715 Programmer Manual for a description of the RS--232 cable requirements.
2. Apply power to the instrument and test equipment, then allow a warmup of
at least one hour.
3. If applicable, set the GPIB address of the 2715 to 1.
Running the Test Equipment Characterization Program (CHAR). The flatness test uses
a power divider and power meter to compensate for flatness variations in the
generator, and for losses in the test system cabling. The flatness test performs this
correction by measuring the signal amplitude at one power divider output (refer to
Figure 5--22), then calculating the amplitude present at the instrument’s RF Input
at the other power divider output. The error in displayed flatness is then corrected
according to the calculated power available at the RF Input.
The CHAR program is designed to measure and record the difference in amplitude
between the power meter and the instrument’s RF Input.1
If a dual channel meter is used, then both outputs are characterized at the same time
using the setup in Figure 5--22. If a single channel power meter is used, test setups
for characterizing the power divider output ports are shown in Figures 5--23 and
5--24. The power meter output of the power divider is characterized by measuring
its output amplitude, with a power meter, across the frequency range while the DUT
output, with min loss pad, is terminated with the 75 Ω termination as in Figure 5--23.
The power meter and termination connections are then made as in Figure 5--24 to
determine the response of the DUT output with the power meter output terminated.
The amplitude difference between the power meter and DUT outputs is then stored
in a data file for later use by the flatness test.
To maintain a traceable calibration standard, this characterization must be
performed whenever the power divider or any pads are replaced. We recommended
dedicating these components to this test system to minimize characterization
requirements.

RPT Results. The following is a description of the results of running RPT.
If units are dBRef (CAL,TS) compute maximum error relative to the reference.
Example:
if absolute (maxError + minError) > absolute (minError -- RefError)
error = maxError -- RefError
else
error = minError -- RefError
If units are dBm (PV,TS) compute the difference between the median of the
measured values and 0.0.
Example:
error = maxError + minError

If units are dB P--P (PV,TS) compute the P--P error.
Example:
error = maxError -- minError
Troubleshooting Flatness Problems. Included with the software is a utility that
allows you to run the flatness over a restricted frequency or attenuator range as a
means of troubleshooting a problem. This utility can also be used to download
flatness data from a previous flatness calibration run into the 2715.
To enter this troubleshooting (TS) sequence, after the Cal Lab Name, and Data
Prompts, select TS sequence.
After selecting the flatness test to run, you will be prompted to either Run
Flatness, or Download Existing Data. Choose the former if you wish to run the
flatness test, and the latter if you wish to download data from a previous Flatness
CAL run.
If you choose Download Existing Data, the software will download the data from
the previous run for this serial number into the 2715. The data it uses is in the
file \tekcats\flatness\2715\<sn>.unc (where <sn> is the serial number of the
2715).
If you choose Run Flatness, you are asked for a start frequency, a stop frequency,
a frequency step size, a start attenuator, and stop attenuator. Note that the test
will always run every attenuator between start attenuator and stop attenuator
(2 dB increments). Also note that the numbers entered above must fit within the
normal range of values. The normal ranges are: 15 MHz to 995 MHz and 0 dB to
40 dB. If you select values outside these ranges, the test will return and not run.

Adjustment Procedures
Next you are prompted to choose between Calibrate Flatness, and Verify Flatness
Calibration. Choose the former to generate a table of flatness corrections to be
downloaded to the 2715. The data will not be automatically downloaded to the
2715, as with the CAL sequence. If you wish to do this, you will need to copy
the file \tekcats\flatness\2715\<sn>.ts to \tekcats\flatness\2715\<sn>.unc Be
aware that if you download a file that does not cover the full frequency or
attenuator range of the CAL sequence tests, the 2715 will not be calibrated for
CATV measurements at some frequency/attenuators.
Choose Verify Flatness Calibration to check the flatness of the 2715 as corrected

Maintenance
This section describes procedures for preventive maintenance, troubleshooting
methods, corrective maintenance, and procedures for recalibrating those
assemblies that normally do not require routine calibration.
Static Sensitive Components
This instrument contains electrical components that can be damaged by static
discharge. See Table 6--1 for the relative susceptibility of various classes of
semiconductors. Static voltages of 1 kV to 30 kV can occur in unprotected
environments.
Observe the following precautions to avoid damage:
H
Minimize handling of static sensitive components.
H
Transport and store static sensitive components or assemblies in their
original containers, on metallized or conductive foam. Label packages that
contain static sensitive assemblies or components.
H
Discharge body static voltage by wearing a grounded wrist strap while
handling these components. Static sensitive assemblies or components
should be handled and serviced only at static free work stations by qualified
service personnel.
H
Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
H
Keep the component leads shorted together whenever possible.
H
Pick up components by the body, never by the leads.
H
Do not slide the components over any surface.
H
Avoid handling components in areas that have a floor or work surface
covering capable of generating a static charge.
H
Use a soldering iron that is connected to earth ground.
H
Use only antistatic suction or wick type desoldering tools.

Preventive Maintenance
Preventive maintenance consists of cleaning, visual inspection, performance check,
and recalibration. The preventive maintenance schedule that is established for the
instrument should be based on the environment in which the instrument is operated
and the amount of use. A preventive maintenance check should be performed every
2000 hours of instrument operation.
Cleaning
Clean the instrument often enough to prevent dust or dirt from accumulating in or
on it. Accumulation of dirt and grease acts as a thermal insulating blanket, prevents
efficient heat dissipation, and provides high resistance leakage paths between
conductors or components in a humid environment.
Do not use any cleaning method that would subject the internal components to
moisture (wet wash).
Exterior. Clean the dust from the outside of the instrument by wiping or brushing the
surface with a soft cloth or small brush. The brush will remove dust from around the
front panel selector buttons. Hardened dirt can be removed with a cloth dampened in
water that contains a mild detergent. Abrasive cleaners should not be used.
Interior. Clean the interior by loosening accumulated dust with a dry soft brush, then
remove the loosened dirt with low pressure air to blow the dust clear. (High velocity
air can damage some components.) Hardened dirt or grease may be removed with a
cotton tipped applicator dampened with a solution of 75% isopropyl alcohol and
rinsed with deionized water. When cleaning front panel buttons use only

Maintenance
deionized water. Abrasive cleaners should not be used. If the circuit board
assemblies need cleaning, remove the circuit board by referring to the instructions under Corrective Maintenance on Page 6--13.
After cleaning, allow the interior to dry thoroughly before applying power to the
instrument.
NOTE. Do not allow water to get inside any enclosed assembly or components
such as the hybrid assemblies, RF Attenuator assembly, potentiometers, etc.
Instructions for removing these assemblies are provided in the Corrective
Maintenance on Page 6--13 part of this section. Do not clean any plastic
materials with organic cleaning solvents such as benzene, toluene, xylene,
acetone, or similar compounds because they may damage the plastic.

Square Pins
Figure 6- 1: Main Extender and Secondary Extender
On the Main Extender, signal lines and power supply lines from the bottom edge
connector to the pins at the top edge of the Extender are completed by a set of
two pin jumpers (excluding two ground lines and the 50 conductor microprocessor bus cable). Thus, except for the two ground lines, all signal and power supply
lines are interruptible via these two pin jumpers.
Signal lines are brought to square pins where they can be steered to one of two
BNC connectors on the Main Extender. See Figure 6--2. There are 20 rows of
3 pin sets numbered 1 through 12 and 17 through 24. The numbers correspond to
pin numbers of the interconnect system on the Power Supply board. Placing a
jumper at position A in Figure 6--2 steers the selected signal to BNC connector A, and a jumper at position B steers the signal to connector B. Consequently,
a maximum of two signals may be steered to the BNC connectors at any one
time.

Conversely, an external signal may be injected on any one of these signal lines
by removing the proper jumper on the signal line, selecting a BNC connector,
and applying the external signal to the selected connector.
The double shielded coaxial cables with SMB connectors and the coaxial cable
with square pin connectors are for interboard connections when needed.
Visual Inspection. After cleaning, carefully check the instrument for such defects
as defective connections and damaged parts. The remedy for most visible defects
is obvious. If heat damaged parts are discovered, try to determine the cause of
overheating before the damaged part is replaced; otherwise, the damage may be
repeated.
Transistor and Integrated Circuit Checks. All transistors and integrated circuits are
soldered on the boards to prevent pin contact problems. Periodic checks of the
transistors and integrated circuits is not recommended. The best measure of
performance is the actual operation of the component in the circuit. In most cases
any degradation in performance will be detected by the microprocessor during
power up. Performance of these components is also checked during
NORMALIZATION; any substandard transistors or integrated circuits will
usually be detected at that time.
2715 Spectrum Analyzer Service Manual
6- 5
Maintenance
Performance Checks and Recalibration. The instrument performance should be
checked after each 2000 hours of operation or every 12 months, if the instrument
is used intermittently, to ensure maximum performance and assist in locating
defects that may not be apparent during regular operation. Instructions for
conducting a performance check are provided in Section 4: Performance
Verification of this manual.
Stored Data in Nonvolatile Memory. Data stored in nonvolatile memory will be lost
if backup battery power to the memory is interrupted, such as when changing the
battery.
Troubleshooting
The Spectrum Analyzer contains firmware that will troubleshoot the frequency
control system. After a defective assembly or component is located, refer to
Removing and Replacing Assemblies and Subassemblies on Page 6--17 for
removal and replacement instructions.
Troubleshooting Aids
The following aids are provided to assist in troubleshooting:
Diagrams. Functional block and circuit diagrams, on foldout pages in the
Diagrams section, contain significant waveforms, voltages, and logic data
information. Conditions for getting the data are provided on the diagram or
adjacent to it. Refer to the Replaceable Electrical Parts list for a description of
all assemblies and components.
Replaceable Electrical Parts. This list indicates changes to components with serial
numbers showing the first serial number when usage of the part occurred and the
last serial number when usage of the part stopped. Absence of serial numbers
indicates the parts were in use since the first instrument shipped. When a major
modification is made to an assembly or board and it is no longer compatible with
earlier instruments, a new part number is assigned and a separate schematic with
associated illustrations is added. All diagrams indicate the new part number and
the instrument serial number break. If the assembly is compatible with earlier
instruments and the change is significant enough to require a separate schematic,
this will also be identified.
Circuit Board Illustrations and Component Locator Charts. Electrical components,
connectors, and test points are identified on circuit board illustrations that are
located on the inside fold of the corresponding circuit diagram or the back of the
preceding diagram. A grid on the circuit board illustration and the circuit
schematic, plus a look up table, provide the means to quickly locate components
on either the diagram or the circuit board.
6- 6
2715 Spectrum Analyzer Service Manual
Maintenance
In most cases, circuit numbers are assigned according to the physical location of
the component on the board or assembly. The first digit designates the row of a
grid and the second a column.
General Troubleshooting Techniques. Before using test equipment to measure
across static sensitive components or assemblies, be certain that voltages and
currents supplied by the test equipment do not exceed the limits of the components to be tested.
Try to isolate the problem to a component through signal analysis. Determine
that circuit voltages will not damage the replacement.
Semiconductor Checks. Semiconductor failures account for the majority of
electronic equipment failures. All semiconductors are soldered to the boards to
reduce pin contact problems. Follow these guidelines when substituting any of
these semiconductors.
H
Always turn the power off before removing an assembly or circuit board.
H
Use a hot air repair terminal to remove surface mounted components, and a
15 W or less soldering iron to remove components with leads.
H
Use only good components for substitution. Be sure the new component is
inserted into the board properly before soldering. Refer to the manufacturer’s
data sheet for integrated circuit and transistor lead configuration.
Diode Checks. Most diodes can be checked in the circuit by taking measurements
across the diode and comparing these with voltages listed on the diagram.
Forward to back resistance ratios can usually be taken by referring to the
schematic and pulling appropriate transistors and pin connectors to remove low
resistance loops around the diode.
NOTE. Do not use an ohmmeter scale with a high external current to check diode
junctions. Do not check the forward to back resistance ratios of mixer diodes.
Diagnostic Firmware. The firmware in the Spectrum Analyzer provides diagnostic
routines that can be used to troubleshoot the Frequency Control system.
2715 Spectrum Analyzer Service Manual

Maintenance
Troubleshooting Steps
The following are some general suggestions that may help isolate a problem
when troubleshooting.
1. Ensure that the problem exists in the Spectrum Analyzer by checking the
operation of associated test equipment.
2. Try to isolate the problem to a circuit or at least to the board level by
evaluating operational symptoms; for example, absence of the frequency dot
could be caused by a malfunction in the marker generator or switching
circuits.
3. Visually inspect the area or assembly for such defects as broken or loose
connections, improperly connected components, overheated or burned
components, chafed insulation, and so forth. Repair or replace all obvious
defects. In the case of overheated components, try to determine the cause of
the overheated condition and correct it before applying power.
4. Use successive electrical checks to try to locate the problem. An oscilloscope
is a valuable test item for evaluating circuit performance. If applicable, check
the calibration adjustments; however, before changing an adjustment, note its
position so it can be returned to its original setting. This will facilitate
recalibration after the trouble has been located and repaired.
5. Determine the extent of the repair needed; if complex, we recommend
contacting your local Tektronix Field Office or representative. If minor, such
as a component replacement, see the Replaceable Parts list for replacement
information. Removal and replacement procedure of the assemblies and
subassemblies are described under Corrective Maintenance later in this
section.
NOTE. When measuring voltages and waveforms, use extreme care with the
placement of test probes. Because some circuit boards have a high component
density, access to points in some circuits is limited. A test probe could accidentally short a circuit and generate transient voltages that can destroy many static
sensitive components.
Cal Debug Flags
From time to time, certain screen messages are displayed when normalizations
are performed with the CAL DEBUG FLAGS turned on (UTIL MENU 5 3 4).
The following is a list of all possible messages the normalizations can produce.

Maintenance
Corrective Maintenance
Corrective maintenance consists of component replacement and instrument
repair. Special techniques and procedures that may be required to remove and
replace assemblies or components in this instrument are described here.
Handling Static Sensitive Components. Most semiconductor types, both separately
and in assemblies, are susceptible to damage to static charge, see Table 6--1 on
Page 6--2 for voltage levels. We recommend static sensitive procedures be
followed for all operations involving semiconductor handling.
Obtaining Replacement Parts. All electrical and mechanical parts are available
through your local Tektronix Field Office or representative. The Replaceable
Parts list contains replacement parts ordering information.
Parts orientation and lead dress should be duplicated, because some components
are oriented to reduce interaction between circuits or control circuit characteristics.
Where applicable, an improved part will be substituted when a replacement is
ordered. If the change is complex, your local Field Office or representative will
contact you concerning the change. After repair, the circuits may need recalibration.
Parts Repair and Return Program. Assemblies containing hybrid circuits or
substrates in a semisealed module, and complex assemblies, such as the 1st LO,
can be returned to Tektronix for repair under the repair and return program.
Tektronix repair centers provide replacement or repair service on major
assemblies as well as the unit. Return the instrument or assembly to your local
Field Office for this service, or contact your local Field Office for repair and
exchange information.
Selected Components. A few components are selected to meet certain parameters
such as temperature compensation, or to center the range of some adjustable
components. The selected components are identified as selectable in the
Replaceable Electrical Parts list. The replaceable parts list description for the
component gives a nominal value. The procedure for selection is explained in the
Maintenance Adjustments.
Replacing Firmware EPROM Devices. Firmware for the microcomputer is
contained in a set of ROMs on the Microprocessor and either GPIB or RS-232
boards. Refer to the Replaceable Electrical Parts list for the versions and part
numbers. Refer to Replacing Transistor and Integrated Circuit for procedure.

Maintenance
Surface Mounted Components. Surface mounted components are used in this
instrument. These components are mounted on pads on the circuit board, rather
than through holes in the board. (In some rare instances, components may be
mounted on pads around through holes.) Lead configurations of these components are shown in Figure 6--3.

Surface mounted semiconductor devices are sensitive to static electricity
discharges and should be treated as outlined in the beginning of this section.
Replacing Surface
Mounted Components
A hot air machine, such as Hart Model 200A manufactured by Nu-Concept
Systems Incorporated of Colmar, Pennsylvania, is recommended for unsoldering
and soldering surface mounted components.
Table 6--3 lists tools that are suitable for servicing circuit boards with surface
mounted components.
Do not apply too much heat or pull hard on the components, as the pads on
which the device is soldered may be lifted from the circuit board.
6- 14
2715 Spectrum Analyzer Service Manual
Maintenance
1. Unsolder the component. Use a solder wick to remove access solder.
2. Clean the board with isopropyl alcohol.
3. Solder in the replacement. Surface mounted components are pretinned, and
therefore require little solder.
CAUTION. If you use a soldering iron, use one with a small tip. After applying the
solder paste, touch the corner of the pad with the iron to fasten the component.
Avoid touching the component with the hot soldering iron. Thermal shock causes
hairline cracks that are not visible to the eye.

Soldering Techniques
NOTE. Disconnect the instrument from its power source before replacing or
soldering components.
Extreme caution must be used when removing or replacing components, because
the instrument contains several multi layer circuit boards. Excess heat from the
soldering iron and bent component leads may pull the plating out of the hole.
Some circuit boards do contain leaded components. To remove the component
leads, use a 15 W (or less) pencil type soldering iron. Straighten the leads on the
back side of the board; when the solder melts, gently pull the soldered lead
through the hole. A desoldering tool should be used to remove the old solder.
Use a desoldering tool that has a low build up of static charge, such as Silverstat
Soldapullt desoldering tool, when unsoldering integrated circuits or transistors.
Transistor and Integrated Circuit Configurations. Lead identification for transistors
and integrated circuits is readily available from manufacturer’s data books.
Integrated circuit pin outs for Vcc and ground are shown with a box on the
schematic diagram.
Diode Color Code. The cathode of each glass encased diode is indicated by a
stripe, a series of stripes, or a dot. Some diodes have a diode symbol printed on
one side.
Resistor Values. Surface mounted resistors have no visible identification.
However, the value can be measured with a meter. Other types of resistors (such
as composition, metal film, tapped, thick film resistor network package, and
plate) are also used. The value is either color coded in accordance with the EIA
color code or printed on the body of the component.
Capacitor Marking. Surface mounted capacitors (chip capacitors) have no visible
markings. The capacitance value, voltage rating, and polarity of electrolytic
capacitors are marked on the side of the component body. The ceramic tubular
capacitors and feed through capacitors are color coded in picofarads.
Multiple Terminal (Harmonica) Connectors. Some intercircuit connections are
made through square pin connectors that are mounted in a harmonica type
holder. If one of the pins must be replaced, all the pins at that location must be
replaced as a set. Most ribbon cable connectors are key6ed. Exceptions are: two
pin connectors, the three pin connector at the back of the Log board, and the 50
pin connector between the Microprocessor, Display Storage, and Digital Options
boards. The key location on the circuit board is identified by a missing pin.

Replacing the CRT
Use the following procedure to replace the CRT.
WARNING. Breaking the CRT may result in an implosion. Protective clothing and
safety glasses should be worn. Avoid hitting the CRT against any object that may
cause the CRT to crack. Place the CRT in a protective carton or place it face
down on a smooth surface in a protected location with a soft mat under the face
plate.
1. Remove the instrument from its cabinet (see Removing the Instrument from
its Cabinet on page 6--17).
2. Remove the circuit board retainer.

Maintenance
3. Disconnect the CRT anode lead and discharge it to the main chassis.
WARNING. The CRT anode lead retains a high voltage charge after the instrument is turned off. To avoid electrical shock, ground the anode lead to the main
chassis immediately after disconnecting.
4. Disconnect the two pin connector (Trace Rotation) from J930 on the Power
Supply board.
5. Use a T15 Torx driver to remove the two CRT bezel screws, and remove the
bezel.
6. Remove the CRT rear cover and plastic shield.
7. Disconnect the CRT socket.
8. Slide the CRT out through the front panel.
Replace the CRT by reversing the removal procedure.
Replacing the CRT Trace
Rotation Coil
The trace rotation coil is part of the CRT assembly. If the coil is damaged beyond
repair, the CRT with the damaged coil must be replaced.
If the finish (red) lead is broken, remove the tape and unwind one or two turns so
it can be replaced and soldered to the lead wire. Rewind and retape.
If the start (black) lead is broken and the lead is too short to resplice, attempt to
fish out the broken end so one or two turns can be unwound, resplice and solder
to the lead; then rewind and retape.
In all three instances, the CRT must be removed from the instrument.
Replacing Semirigid
Coaxial Cables
Performance of the instrument is easily degraded if coaxial connectors are loose,
dirty, or damaged. The following procedure will help ensure that the connection
is good enough to maintain proper performance.
1. Use a 5/16 inch open end wrench to loosen or tighten the connectors. It is
good practice to use a second wrench to hold the rigid (receptacle) portion of
the connector to prevent bending or twisting the cable.
2. Ensure that the plug and receptacle are clean and free of any foreign matter.
3. Insert the plug connector fully into the receptacle before screwing the nut on.
Tighten the connection to 8 in-lb to ensure that the connection is tight. Do
not overtighten, because this can damage the connector.

The schematic diagram and circuit board component location illustrations have grids marked
on them. The component lookup tables refer to these grids to help you locate a component.
The circuit board illustration appears only once; its lookup table lists the diagram number of
all diagrams on which the circuitry appears.
Some of the circuit board component location illustrations are expanded and divided into
several parts to make it easier for you to locate small components. To determine which part
of the whole locator diagram you are looking at, refer to the small locator key shown below.
The gray block, within the larger circuit board outline, shows where that part fits in the
whole locator diagram. Each part in the key is labeled with an identifying letter that appears
in the figure titles under component locator diagrams.
