HP 70000 Modular Measurement System Documentation Outline
Instruments and modules of the HP 70000 Modular Measurement System are documented
to varying levels of detail. Modules that serve as masters of an instrument require operation
information in addition to installation and verication instructions. Modules that function as
slaves in a system require only a subset of installation and verication information.
Manuals Supplied with Module
Installation and Verication Manual
Topics covered by this manual include installation, specications, verication of module
operation, and some troubleshooting techniques. Manuals for modules that serve as
instrument masters will supply information in all these areas; manuals for slave modules will
contain only information needed for slave module installation and verication. Master module
documentation may also include some system-level information.
Operation Manual
Operation Manuals usually pertain to multiple- and single-module instrument systems. Topics
include preparation for module use, module functions, and softkey denitions.
Programming Manual
Programming Manuals also pertain to multiple- and single-module instrument systems.
Programming Manual topics include programming fundamentals and denitions for remote
programming commands.

Start-Up Procedures
2-1
Configuring the Hardware
1. Connect the HP 70000 Series modular spectrum analyzer to the computer port determined
by the following criteria:
a. For computers with an additional HP 98624A HP-IB Interface, connect your spectrum
analyzer to the port labeled HP-IB SELECT CODE 8. Check that the address switch on
the HP 98624A HP-IB Interface board assembly matches the HP-IB controller device
address. If needed, refer to the HP 9000 Series 200/300 Peripheral Installation Guide,
Volume 1 .
b. For computers without an HP 98624A HP-IB Interface, connect the HP 70000 Series
modular spectrum analyzer to the port labeled HP-IB SELECT CODE 7.
2. Connect the HP-IB cables from the test equipment to the computer's HP-IB SELECT
CODE 7 port.
3. Use a 0.5 meter HP-IB cable (HP 10833D, or similar cable) to connect the external disk
drive's HP-IB to the HP-IB SELECT CODE 7 port.
Note
Occasionally disk drives exhibit unpredictable behavior when sharing the
HP-IB with instruments. If you nd this occurring, connect the disk drive to a
separate HP-IB interface.
4. Set the external test equipment and the HP 70000 Series modular spectrum analyzer
line switches to ON. Allow the equipment to warm up at least 1 hour for the system
performance tests.

Start-Up Procedures
System Performance Test Software
This section contains a procedure for installing the program. More specic program-operation
information is contained in Chapter 3, \Menus."
Two assumptions are made with the System Performance Test software: that you are using
standard HP-IB addresses for the test equipment, and that all passive devices are available. If
either of these assumptions is incorrect, you must use the \Equipment Menu Edit Screen" to
correctly congure your test equipment.
Note
The program software version and the program part number will be needed
if you contact Hewlett-Packard about this software. The software version of
the program is visible on the right-hand side of the display that appears after
the rst program disk is loaded. It is also visible in the Main Menu and the
Test Menu. Specic numbers vary, but the version number looks like this:
Rev. A.02.00. The program part number is printed on the disk labels.
Installing System Performance Test Software onto an HP 9133
1. Load BASIC 4.0 or later, with the appropriate binaries, into an HP 9000 Series 200/300
computer. If necessary, refer to an HP BASIC reference manual.
Caution
Make backup copies of all disks. If the program data on an individual disk
should become altered, it cannot be ordered separately. The entire set of disks
must be ordered to replace any one disk.
2. Assign the MSI (mass storage is) to the oppy drive of the HP 9133. As an example,
assigning the MSI to the oppy disk drive should be similar to the following:
MSI ":,700,1"
3. Insert the Executive disk into the default oppy drive and type in the following:
LOAD"INSTAL_HFS",1
4Return5
A screen prompt titled \PROCESS OVERVIEW" will appear. Please read the entire

NNNNNNNNNNNNNNNNNNNNNNNNNN
Do you want to copy any OPTION discs? (Y or N)
Note
It is important at this time to decide whether you would like to copy your
option performance tests to the hard drive. When the display screen prompts
you to copy disks for your option software, this will be the only opportunity to
copy your option performance tests to the hard drive.
If you do not want to copy the performance tests for your option to the hard drive,
answering No to the above prompt completes the installation procedure. Otherwise, a
screen prompt for each available option (in numerical order) will appear allowing you to
copy performance tests to the hard drive.
8. Insert the Test disk for your option making sure to select the correct screen prompt that
matches your option, then press CONTINUE .
After you have completed copying your option(s) performance tests onto the hard drive,

Mass Storage Menu
The Mass Storage Menu has both an edit screen and a command screen. The edit screen
displays a list of mass storage information and allows you to assign the areas where the
program stores system and operation data. This is done by assigning volume labels to a mass
storage unit specier (msus). An msus is a string expression that points to a mass storage
location. The command screen allows you to save the mass storage information after it is
entered. Refer to \Mass Storage Menu Volume Labels" and \Editing Mass Storage Menu
Information" below. Figure 3-2 illustrates the Mass Storage Menu softkey organization.
Mass Storage Menu Volume Labels
The BASIC operating system can use a number of mass storage devices. These include
internal disk drives, external disk drives, and SRM systems. A mass storage Volume is
composed of one or more les. Files are data items or subprograms. A Volume might consist
entirely of les on a oppy disk, or some number of les on a small portion of a hard disk.
The Mass Storage Menu lists volume labels, which show the location of certain types of
program information. Volume labels each have a default msus. From the Mass Storage Menu,
you can reassign the current msus or directory path designation to another designation. You
cannot edit volume labels, but you may edit their msus designations and directory path data
elds.
The volume labels are explained below.

Description
This test measures the incremental RF output amplitude accuracy of the tracking generator
over 021 dBm to 010 dBm, the range of the automatic level control (ALC).
The tracking generator frequency is set to 300 MHz, the ALC normal detector is selected, and
the tracking generator's attenuator (if present) is set to 0 dB. The tracking generator output
power is set to 010 dBm, and a reference reading is taken with the power meter. The output
power is then stepped in 1 dB increments over the 021 dBm to 011 dBm range. The absolute
error between the programmed amplitude (what was expected) and the power meter reading
(what was measured) is stored. The dierences in the absolute errors are checked to see if
they meet incremental specications.
The above procedure is repeated at 1 MHz with the ALC alternate detector.

the alternate detector, the range tested is 100 kHz to 10 MHz.
A reference amplitude of 010 dBm is set at 300 MHz using the normal detector. The
amplitude over the frequency range of the normal detector is increased in 60 linear steps from
highest to lowest. Each step is measured for any deviation from the reference amplitude.
The same procedure is used to measure the amplitude deviation over the frequency range of
the alternate detector, with the 010 dBm reference set at 1 MHz.

calibration is made in 100 MHz increments over the frequency range of 10 MHz to 22 GHz*.
The setting of the microwave spectrum analyzer RF attenuator is stored along with the
calibration data.
Connect the equipment using setup B. The second through fth harmonic levels below
2.9 GHz are measured with respect to the maximum leveled output power of the DUT.
Measurements are made at nine fundamental frequencies over the 10 MHz to 2.9 GHz
range. The DUT is set to an RF output level of 010 dBm, and for zero span operation. The
microwave spectrum analyzer RF attenuator is set to the same value that was used during
calibration. Resolution bandwidth is set to 30 kHz and the frequency span is set to 1 MHz.
At each fundamental frequency, the amplitude of the fundamental is measured by the
microwave spectrum analyzer, and the amplitude is corrected using the atness calibration
data. The second through fth harmonic levels are then measured, corrected, and compared
to specications.

Introduction
The HP 11990A Option 100 System Software package provides all test software required
to verify that an HP 71100A, HP 71100C, or HP 71150C spectrum analyzer meets all of its
major specications. This system software package consists of this manual and one test disk
(Test Disk 1). A System Add-On package may be needed to test modules that are not part
of a predened system. For example, although the tracking generator tests are listed in the
Test Menu, these tests are not included in the system software package. The HP 11990A
Option 033 System Add-On package contains the tracking generator tests.
Execution of the tests in this system software package is dependent on the HP 11990A Option
001 User Interface program, which automates the test process. Refer to Chapter 2, \Start-Up
Procedures," for instructions to run the test software.

Equipment Setup
The H SWP output on the rear panel of the HP 70900 local oscillator is connected to the
input of the universal counter. If an HP 70700A digitizer is in the system, the H SWP line
from the HP 70900 must also be connected to the digitizer rear-panel HI SWP connector.
Description
Several dierent spectrum-analyzer sweep times are selected to exercise the hardware fully.
For each selected sweep time, the DUT is set for a span of 0 Hz and a sweep is triggered. The
sweep time is then measured with the universal counter. Sweep times are selected to turn on
each of the 12 bits of the sweep DAC. Only one bit is on at a time except when the lower six
bits are tested; then bit 6 is also on.
If the HP 70700A digitizer is in the system, then its hardware must also be tested. Several
more sweep times are chosen to test: fast sweep times at multiples of the digitizer's clock rate,
worst-case resolution errors, and long sample rates.

Description
The third-order intermodulation (TOI) of the DUT is measured at approximately 45 MHz
using the 3 kHz resolution bandwidth (100 kHz in the HP 70903A). It is tested at several
signal separations.
First, the amplitude of the general-source output is measured to establish the TOI reference
amplitude level. Then the amplitude of the level-generator output is measured to establish the
signal level. The upper third-order-product signal level is then measured, and the equivalent
TOI is calculated as follows:
(TOI reference ampl:) 0 (third0order ampl:) [(signal level) 0 (DUT input atten: setting)] +
2
This procedure is repeated for the lower TOI product. The smaller value of the equivalent
TOI is retained.

Description
The level generator is set to produce a signal within the range of the DUT. The DUT is tuned
to this signal, and the input attenuator is set to 10 dB. The DUT is set to zero span and the
level generator is tuned to the center of the DUT passband.
The amplitude of the level generator is adjusted until a signal of 030 dBm or less is at the
DUT input mixer. The measurement receiver then measures signal path gain; this value is
used as the reference for no gain compression.
The level-generator amplitude is increased to produce a signal of 010 dBm at the DUT input
mixer. The measurement receiver again measures signal path gain. The dierence between the
two gain measurements is the gain compression.

Frequency readout accuracy is tested at a maximum of eight frequencies and four spans. For
each span and source frequency, the frequency readout of the DUT is compared to that of
a synthesized source. The source is set to the selected center frequency of the DUT. The
signal is marker-peaked. The deviation between the marker frequency readout and the center
frequency is the frequency error. This test is performed with the DUT referenced to the

is averaged. The data is normalized to a 1 Hz bandwidth and corrected for log detection and

Description
This test measures the relative on-screen log scale delity (that is, the display CRT's upper
eight divisions for the HP 70903A, or upper nine divisions for the HP 70902A).
The DUT is set for a reference level of +10 dBm, span of 0 Hz, and a resolution bandwidth of
100 kHz (HP 70903A) or 100 Hz (HP 70902A). The level-generator frequency is adjusted to
peak the detected signal, and the amplitude is adjusted to set the signal at the reference level.
The dierence between the level generator and marker amplitudes establishes a reference error
at this point.
The level generator is stepped down in 1 dB increments (2 dB in Limited Cal and All Tests
modes) until the signal is 75 to 90 dB below top-screen. The actual level depends on the IF
and RF being tested. In the last 20 dB of the log range, the sweep time is increased to lessen
the eects of the reduced signal-to-noise ratio. The amplitude dierence between the level
generator and the displayed trace average is measured. Once all measurements have been
made, the data is normalized to 010 dB of top-screen.
If the HP 70700A digitizer is in the system, the test is repeated with the digitizer selected.

Equipment Setup

Description
Bandwidth switching variation is tested by setting a reference value at the widest resolution
bandwidth. The DUT resolution bandwidth is then stepped down in a 1, 3, 10 sequence and
the amplitude variation from the widest bandwidth is recorded. The data is then normalized
to the reference bandwidth (100 Hz, HP 70902A; 300 kHz, HP 70903A).
The 3 dB (or 60 dB) points of the resolution bandwidth response are tested as follows.
The DUT is set to the 0 Hz span and the level-generator frequency is adjusted to peak the
response. The level-generator amplitude is then stepped down 3 dB to establish a reference
value. The level- generator amplitude is then returned to the original value and the frequency
is decreased until the 3 dB reference amplitude is reached. This establishes the lower 3 dB
frequency point. The level-generator frequency is then increased until the upper 3 dB point
is found. The dierence in level-generator frequencies is the 3 dB bandwidth. This procedure
may be repeated to determine the 60 dB points of the resolution bandwidth response.

Introduction
The HP 11990A Option 200 System Software package provides all test software required
to verify that an HP 71200A, HP 71201A, or HP 71200C spectrum analyzer meets all of its
major specications. This system software package consists of this manual and one test disk
(Test Disk 1). A System Add-On package may be needed to test modules that are not part of
a predened system. For example, although the tracking generator tests are listed in the Test
Menu, these tests are not included in the system software package. The HP 11990A Option
033 System Add-On package contains the tracking generator tests.
Execution of the tests in this system software package is dependent on the HP 11990A Option
001 User Interface program, which automates the test process. Refer to Chapter 2, \Start-Up
Procedures," for instructions to run the test software.

Equipment Setup
The H SWP output on the rear panel of the HP 70900 local oscillator is connected to the
input of the universal counter. If an HP 70700A digitizer is in the system, the H SWP line
from the HP 70900 must also be connected to the digitizer rear-panel HI SWP connector.
Description
Several dierent spectrum-analyzer sweep times are selected to exercise the hardware fully.
For each selected sweep time, the DUT is set for a span of 0 Hz and a sweep is triggered. The
sweep time is then measured with the universal counter. Sweep times are selected to turn on
each of the 12 bits of the sweep DAC. Only one bit is on at a time except when the lower six
bits are tested; then bit 6 is also on.
If the HP 70700A digitizer is in the system, then its hardware must also be tested. Several
more sweep times are chosen to test: fast sweep times at multiples of the digitizer's clock rate,
worst-case resolution errors, and long sample rates.

Description
The third-order intermodulation (TOI) of the DUT is measured at approximately 45 MHz
using the 3 kHz resolution bandwidth (100 kHz in the HP 70903A). It is tested at several
signal separations.
First, the amplitude of the general-source output is measured to establish the TOI reference
amplitude level. Then the amplitude of the level-generator output is measured to establish the
signal level. The upper third-order-product signal level is then measured, and the equivalent
TOI is calculated as follows:
(TOI reference ampl:) 0 (third0order ampl:) [(signal level) 0 (DUT input atten: setting)] +

This procedure is repeated for the lower TOI product. The smaller value of the equivalent
TOI is retained.

The level generator is set to produce a signal within the range of the DUT. The DUT is tuned
to this signal, and the input attenuator is set to 10 dB. The DUT is set to zero span and the
level generator is tuned to the center of the DUT passband.
The amplitude of the level generator is adjusted until a signal of 030 dBm or less is at the
DUT input mixer. The measurement receiver then measures signal path gain; this value is
used as the reference for no gain compression.
The level-generator amplitude is increased to produce a signal of 010 dBm at the DUT input
mixer. The measurement receiver again measures signal path gain. The dierence between the
two gain measurements is the gain compression.

Equipment Setup
A low-loss cable such as HP part number 8120-3124 must be used to connect

Note
Setup A: Connect the HP 70900 local oscillator CALIBRATOR output to the HP 70600A or
HP 70601A RF INPUT to calibrate the preselected front end.
Setup B: Connect the source output to the input connector of the power splitter. Connect one
output of the power splitter to the RF INPUT of the HP 70600A or HP 70601A preselector.
Connect the other output from the power splitter to the power sensor, which is connected to
the power meter.
Setup C: (For measurements below 50 MHz only) Connect the level-generator output to the
RF INPUT of the HP 70600A or HP 70601A Preselector.
Description
The algorithm used in this test is the same as for the HP 70905A and HP 70906A RF section
verication tests. The dierence is that this test is run twice, once in the preselected mode
and once in the bypass mode. In the preselected mode, the preselector is peaked before
making each measurement. For both modes, the measurements are made in 3 kHz resolution
bandwidth when the HP 70902A IF section is in the system. The purpose of using this
bandwidth is to eliminate any local oscillator drift during preselector peaking. If only the
wide-band HP 70903A IF section is in the system, the 300 kHz resolution bandwidth is used.
Once the modular spectrum analyzer and power meter have been calibrated, setup B is
veried and the HP 70600A or HP 70601A attenuator is set to 10 dB. Then the preselector
mode is enabled. Next the source power level is adjusted for a power-meter reading of
010 dBm at 300 MHz. The amplitude of the preselector is then measured to set a reference
amplitude.
Starting with the highest band, each band is path-locked while amplitude measurements are
taken at various preselector frequencies with the power meter. If the preselected mode is
enabled, the preselector is peaked in zero span prior to each measurement, then returned to

the preselector is the amplitude measurement error for the frequency measured.
In all modes except Limited Cal mode, frequencies below 50 MHz are measured using a level
generator. Setup C is veried and various frequencies below 50 MHz are measured.
Next, the preselector bypass mode is enabled, and the measurements are repeated once,
starting at the 010 dBm, 300 MHz reference amplitude measurement.

Equipment Setup

INPUT.
Description
Frequency readout accuracy is tested at a maximum of eight frequencies and four spans. For
each span and source frequency, the frequency readout of the DUT is compared to that of
a synthesized source. The source is set to the selected center frequency of the DUT. The
signal is marker-peaked. The deviation between the marker frequency readout and the center
frequency is the frequency error. This test is performed with the DUT referenced to the
internal frequency reference.
If the signal amplitude is close to the noise level due to a cable that has a large amount of
signal loss, the measurement is not recorded.
If the HP 70700A digitizer is in the system, the entire test is repeated with the external
digitizer selected. In addition, extra frequencies are selected to check the area of band
crossings in microwave systems.

Description
The DUT center frequency is set to 1.5 GHz, and spans of 10 kHz, 100 kHz, 1 MHz, 10 MHz,
10.01 MHz, 101 MHz, and 1.01 GHz are tested. The synthesizer frequency is adjusted until
a signal appears near the left edge of the display. The frequency of this point and several
other points in the span are noted by using marker peak. The deviation between the marker
frequency and the synthesizer frequency is the absolute error. The maximum frequency span
error is calculated by taking the dierence between the maximum and minimum absolute
errors.
This test is performed with the DUT referenced to the internal frequency reference.
If the HP 70700A digitizer is in the system, the test is repeated with the external digitizer
selected.

HP 70601A RF INPUT, to calibrate the preselected front end.
Setup B: Connect the source output to the RF INPUT of the HP 70600A or HP 70601A
preselector.
Description
This test measures image responses for osets of twice the IF frequency from the center
frequency on the spectrum analyzer under test. These osets are 6 MHz, 42.8 MHz, and
642.8 MHz. The ve tuning bands (1H0, 1L0, 2L0, 3L+, 4L+) are tested in the preselected
mode only. For bands 0 to 12.7 GHz, attenuation is set to 10 dB; for bands 12.5 to 22 GHz,
attenuation is set to 0 dB to maximize dynamic range. In the 12.5 to 22 GHz bands, the
preselector is peaked in zero span, then returned to the test span.
An output from the source is applied to the HP 70600A or HP 70601A preselector RF INPUT
and a reference amplitude is obtained. The source frequency is then changed to an oset of
twice the IF frequency, and the peak amplitude is read. The dierence between the reference
amplitude and the peak amplitude equals the image amplitude in dBc. If the test frequency
fails specications, it will be retested in a narrower resolution bandwidth and video bandwidth
to reduce noise contributions.
In Limited Cal mode, the 6 MHz and 42.8 MHz image frequencies are tested only in the
low-pass lter mode, and the 642.8 MHz image frequency is tested in all bands.

Description
This test measures multiple responses of an HP 71201A microwave spectrum analyzer. All ve
tuning bands (1H0, 1L0, 2L0, 3L+, 4L+) are tested in the preselected mode only. For bands
0 to 12.7 GHz, attenuation is set to 10 dB; for bands 12.5 to 22 GHz, attenuation is set to 0
dB to maximize dynamic range. In the 12.5 to 22 GHz bands, the preselector is peaked in
zero span, then is returned to the test span.
A list of source frequencies is generated that should produce a multiple response
corresponding to a given center frequency. The source frequency is set to the center frequency
and a reference amplitude is obtained. Next, the source frequency is set to frequencies on the
list where a response level is obtained for each of the frequencies. The dierence between
the amplitudes of the reference frequency and the level of each list frequency is the multiple
response amplitude in dBc. If the test results plus the maximum amplitude error due to the
IF response time is close to specication, the multiple response is measured again at a slower
sweep rate to reduce the IF response-time error.

Description
This test measures the relative on-screen log scale delity (that is, the display CRT's upper
eight divisions for the HP 70903A, or upper nine divisions for the HP 70902A).
The DUT is set for a reference level of +10 dBm, span of 0 Hz, and a resolution bandwidth of
100 kHz (HP 70903A) or 100 Hz (HP 70902A). The level-generator frequency is adjusted to
peak the detected signal, and the amplitude is adjusted to set the signal at the reference level.
The dierence between the level generator and marker amplitudes establishes a reference error
at this point.
The level generator is stepped down in 1 dB increments (2 dB in Limited Cal and All Tests
modes) until the signal is 75 to 90 dB below top-screen. The actual level depends on the IF
and RF being tested. In the last 20 dB of the log range, the sweep time is increased to lessen
the eects of the reduced signal-to-noise ratio. The amplitude dierence between the level
generator and the displayed trace average is measured. Once all measurements have been
made, the data is normalized to 010 dB of top-screen. If the HP 70700A digitizer is in the
system, the test is repeated with the digitizer selected.

Description
Bandwidth switching variation is tested by setting a reference value at the widest resolution
bandwidth. The DUT resolution bandwidth is then stepped down in a 1, 3, 10 sequence and
the amplitude variation from the widest bandwidth is recorded. The data is then normalized
to the reference bandwidth (100 Hz, HP 70902A; 300 kHz, HP 70903A).
The 3 dB (or 60 dB) points of the resolution bandwidth response are tested as follows.
The DUT is set to the 0 Hz span and the level-generator frequency is adjusted to peak the
response. The level-generator amplitude is then stepped down 3 dB to establish a reference
value. The level- generator amplitude is then returned to the original value and the frequency
is decreased until the 3 dB reference amplitude is reached. This establishes the lower 3 dB
frequency point. The level-generator frequency is then increased until the upper 3 dB point
is found. The dierence in level-generator frequencies is the 3 dB bandwidth. This procedure
may be repeated to determine the 60 dB points of the resolution bandwidth response.

Introduction
The HP 11990A Option 209 System Software package provides all test software required
to verify that an HP 71209A, HP 71209C, or HP 71250C spectrum analyzer meets all of its
major specications. This software package consists of this manual and one test disk (Test
Disk 1). A System Add-On package may be needed to test modules that are not part of a
predened system. For example, although the tracking generator tests are listed in the Test
Menu, these tests are not included in the system software package. The HP 11990A Option
033 System Add-On package contains the tracking generator tests.
Execution of the tests in this system software package is dependent on the HP 11990A Option
001 User Interface program, which automates the test process. Refer to Chapter 2, \Start-Up
Procedures," for instructions to run the test software.

Equipment Setup
The H SWP output on the rear panel of the HP 70900 local oscillator is connected to the
input of the universal counter. If an HP 70700A digitizer is in the system, the H SWP line
from the HP 70900 must also be connected to the digitizer rear-panel HI SWP connector.
Description
Several dierent spectrum-analyzer sweep times are selected to exercise the hardware fully.
For each selected sweep time, the DUT is set for a span of 0 Hz and a sweep is triggered. The
sweep time is then measured with the universal counter. Sweep times are selected to turn on
each of the 12 bits of the sweep DAC. Only one bit is on at a time except when the lower six
bits are tested; then bit 6 is also on.
If the HP 70700A digitizer is in the system, then its hardware must also be tested. Several
more sweep times are chosen to test: fast sweep times at multiples of the digitizer's clock rate,
worst-case resolution errors, and long sample rates.

using the 3 kHz resolution bandwidth (100 kHz in the HP 70903A). It is tested at several

First, the amplitude of the general-source output is measured to establish the TOI reference
amplitude level. Then the amplitude of the level-generator output is measured to establish the
signal level. The upper third-order-product signal level is then measured, and the equivalent
TOI is calculated as follows:
(TOI reference ampl:) 0 (third0order ampl:) [(signal level) 0 (DUT input atten: setting)] +

This procedure is repeated for the lower TOI product. The smaller value of the equivalent
TOI is retained.

a synthesized source. The source is set to the selected center frequency of the DUT. The
signal is marker-peaked. The deviation between the marker frequency readout and the center

An output from the source is applied to the HP 70908A RF INPUT and a reference amplitude
is obtained. The source frequency is then changed to an oset of twice the IF frequency, and
the peak amplitude is read. The dierence between the reference amplitude and the peak

Description
This test measures multiple responses of an HP 71210 spectrum analyzer. All four tuning
bands (1H0, 1L0, 2L0, 4L0) are tested.
A list of source frequencies is generated that should produce a multiple response
corresponding to a given center frequency. The source frequency is set to the center frequency
and a reference amplitude is obtained. Next, the source frequency is set to frequencies on the
list where a response level is obtained for each of the frequencies. The dierence between the
amplitudes of the reference frequency and the level of each listed frequency is the multiple
response amplitude in dBc. If the test results plus the maximum amplitude error due to the
IF response time are close to specication, the multiple response is measured again at a slower
sweep rate to reduce the IF response-time error.
In single mode, the center frequency is stepped up in 500 MHz increments. In all other test
modes, it is stepped up in 1 GHz increments (27 measurements).

Description
This test measures the relative on-screen log scale delity (that is, the display CRT's upper

The DUT is set for a reference level of +10 dBm, span of 0 Hz, and a resolution bandwidth of
100 kHz (HP 70903A) or 100 Hz (HP 70902A). The level-generator frequency is adjusted to
peak the detected signal, and the amplitude is adjusted to set the signal at the reference level.
The dierence between the level generator and marker amplitudes establishes a reference error
at this point.
The level generator is stepped down in 1 dB increments (2 dB in Limited Cal and All Tests
modes) until the signal is 75 to 90 dB below top-screen. The actual level depends on the IF
and RF being tested. In the last 20 dB of the log range, the sweep time is increased to lessen
the eects of the reduced signal-to-noise ratio. The amplitude dierence between the level
generator and the displayed trace average is measured. Once all measurements have been

Description
Bandwidth switching variation is tested by setting a reference value at the widest resolution
bandwidth. The DUT resolution bandwidth is then stepped down in a 1, 3, 10 sequence and
the amplitude variation from the widest bandwidth is recorded. The data is then normalized
to the reference bandwidth (100 Hz, HP 70902A; 300 kHz, HP 70903A).
The 3 dB (or 60 dB) points of the resolution bandwidth response are tested as follows.
The DUT is set to the 0 Hz span and the level-generator frequency is adjusted to peak the
response. The level-generator amplitude is then stepped down 3 dB to establish a reference
value. The level- generator amplitude is then returned to the original value and the frequency
is decreased until the 3 dB reference amplitude is reached. This establishes the lower 3 dB
frequency point. The level-generator frequency is then increased until the upper 3 dB point
is found. The dierence in level-generator frequencies is the 3 dB bandwidth. This procedure

Equipment Setup
The H SWP output on the rear panel of the HP 70900 local oscillator is connected to the
input of the universal counter. If an HP 70700A digitizer is in the system, the H SWP line
from the HP 70900 must also be connected to the digitizer rear-panel HI SWP connector.
Description
Several dierent spectrum-analyzer sweep times are selected to exercise the hardware fully.
For each selected sweep time, the DUT is set for a span of 0 Hz and a sweep is triggered. The
sweep time is then measured with the universal counter. Sweep times are selected to turn on
each of the 12 bits of the sweep DAC. Only one bit is on at a time except when the lower six
bits are tested; then bit 6 is also on.
If the HP 70700A digitizer is in the system, then its hardware must also be tested. Several
more sweep times are chosen to test: fast sweep times at multiples of the digitizer's clock rate,
worst-case resolution errors, and long sample rates.

Description
The third-order intermodulation (TOI) of the DUT is measured at approximately 45 MHz
using the 3 kHz resolution bandwidth (100 kHz in the HP 70903A). It is tested at several
signal separations.
First, the amplitude of the general-source output is measured to establish the TOI reference
amplitude level. Then the amplitude of the level-generator output is measured to establish the
signal level. The upper third-order-product signal level is then measured, and the equivalent
TOI is calculated as follows:
(TOI reference ampl:) 0 (third0order ampl:) [(signal level) 0 (DUT input atten: setting)] +
2
This procedure is repeated for the lower TOI product. The smaller value of the equivalent
TOI is retained.

The level generator is set to produce a signal within the range of the DUT. The DUT is tuned
to this signal, and the input attenuator is set to 10 dB. The DUT is set to zero span and the
level generator is tuned to the center of the DUT passband.
The amplitude of the level generator is adjusted until a signal of 030 dBm or less is at the
DUT input mixer. The measurement receiver then measures signal path gain; this value is
used as the reference for no gain compression.
The level-generator amplitude is increased to produce a signal of 010 dBm at the DUT input
mixer. The measurement receiver again measures signal path gain. The dierence between the
two gain measurements is the gain compression.

Description
Frequency readout accuracy is tested at a maximum of eight frequencies and four spans. For
each span and source frequency, the frequency readout of the DUT is compared to that of
a synthesized source. The source is set to the selected center frequency of the DUT. The
signal is marker-peaked. The deviation between the marker frequency readout and the center
frequency is the frequency error. This test is performed with the DUT referenced to the
internal frequency reference.
If the signal amplitude is close to the noise level due to a cable that has a large amount of
signal loss, the measurement is not recorded.
If the HP 70700A digitizer is in the system, the entire test is repeated with the external
digitizer selected. In addition, extra frequencies are selected to check the area of band

The DUT center frequency is set to 1.5 GHz, and spans of 10 kHz, 100 kHz, 1 MHz, 10 MHz,
10.01 MHz, 101 MHz, and 1.01 GHz are tested. The synthesizer frequency is adjusted until
a signal appears near the left edge of the display. The frequency of this point and several
other points in the span are noted by using marker peak. The deviation between the marker
frequency and the synthesizer frequency is the absolute error. The maximum frequency span
error is calculated by taking the dierence between the maximum and minimum absolute
errors.
This test is performed with the DUT referenced to the internal frequency reference.

INPUT, to calibrate the preselected front end.
Setup B: Connect the source output to the RF INPUT of the HP 70908A RF section.
Description
This test measures image responses for osets of twice the IF frequency from the center
frequency on the spectrum analyzer under test. These osets are 6 MHz, 42.8 MHz, and
642.8 MHz. All four tuning bands (1H0, 1L0, 2L0, 4L0) are tested.
An output from the source is applied to the HP 70908A RF INPUT and a reference amplitude
is obtained. The source frequency is then changed to an oset of twice the IF frequency, and
the peak amplitude is read. The dierence between the reference amplitude and the peak
amplitude equals the image amplitude in dBc. If the test frequency fails specications, it
will be retested in a narrower resolution bandwidth and video bandwidth to reduce noise
contributions.

Description
This test measures multiple responses of an HP 71210 spectrum analyzer. All four tuning
bands (1H0, 1L0, 2L0, 4L0) are tested.
A list of source frequencies is generated that should produce a multiple response
corresponding to a given center frequency. The source frequency is set to the center frequency
and a reference amplitude is obtained. Next, the source frequency is set to frequencies on the
list where a response level is obtained for each of the frequencies. The dierence between the
amplitudes of the reference frequency and the level of each listed frequency is the multiple
response amplitude in dBc. If the test results plus the maximum amplitude error due to the
IF response time are close to specication, the multiple response is measured again at a slower
sweep rate to reduce the IF response-time error.
In single mode, the center frequency is stepped up in 500 MHz increments. In all other test
modes, it is stepped up in 1 GHz increments (27 measurements).

This test measures the relative on-screen log scale delity (that is, the display CRT's upper
eight divisions for the HP 70903A, or upper nine divisions for the HP 70902A).
The DUT is set for a reference level of +10 dBm, span of 0 Hz, and a resolution bandwidth of
100 kHz (HP 70903A) or 100 Hz (HP 70902A). The level-generator frequency is adjusted to
peak the detected signal, and the amplitude is adjusted to set the signal at the reference level.
The dierence between the level generator and marker amplitudes establishes a reference error
at this point.
The level generator is stepped down in 1 dB increments (2 dB in Limited Cal and All Tests
modes) until the signal is 75 to 90 dB below top-screen. The actual level depends on the IF
and RF being tested. In the last 20 dB of the log range, the sweep time is increased to lessen
the eects of the reduced signal-to-noise ratio. The amplitude dierence between the level
generator and the displayed trace average is measured. Once all measurements have been
made, the data is normalized to 010 dB of top-screen.
If the HP 70700A digitizer is in the system, the test is repeated with the digitizer selected.

Level generator relative amplitude accuracy

Description
Bandwidth switching variation is tested by setting a reference value at the widest resolution
bandwidth. The DUT resolution bandwidth is then stepped down in a 1, 3, 10 sequence and
the amplitude variation from the widest bandwidth is recorded. The data is then normalized
to the reference bandwidth (100 Hz, HP 70902A; 300 kHz, HP 70903A).
The 3 dB (or 60 dB) points of the resolution bandwidth response are tested as follows.
The DUT is set to the 0 Hz span and the level-generator frequency is adjusted to peak the
response. The level-generator amplitude is then stepped down 3 dB to establish a reference
value. The level- generator amplitude is then returned to the original value and the frequency
is decreased until the 3 dB reference amplitude is reached. This establishes the lower 3 dB
frequency point. The level-generator frequency is then increased until the upper 3 dB point
is found. The dierence in level-generator frequencies is the 3 dB bandwidth. This procedure
may be repeated to determine the 60 dB points of the resolution bandwidth response.

Introduction
The HP 11990A Option 300 System Software package provides all test software required to
verify that an HP 71300A millimeter spectrum analyzer meets all of its major specications.
This software package can also be used when an HP 70907A is a secondary input of an
HP 71100C, HP 71200C, or HP 71210C spectrum analyzer. This software package consists of
this manual and one test disk (Test Disk 1). A System Add-On package may be needed to
test modules that are not part of a predened system.
Execution of the tests in this system software package is dependent on the HP 11990A Option
001 User Interface program, which automates the test process. Refer to Chapter 2, \Start-Up
Procedures," for instructions to run the test software.

Equipment Setup
The H SWP output on the rear panel of the HP 70900 local oscillator is connected to the
input of the universal counter. If an HP 70700A digitizer is in the system, the H SWP line
from the HP 70900 must also be connected to the digitizer rear-panel HI SWP connector.
Description
Several dierent spectrum-analyzer sweep times are selected to exercise the hardware fully.
For each selected sweep time, the DUT is set for a span of 0 Hz and a sweep is triggered. The
sweep time is then measured with the universal counter. Sweep times are selected to turn on
each of the 12 bits of the sweep DAC. Only one bit is on at a time except when the lower six
bits are tested; then bit 6 is also on.
If the HP 70700A digitizer is in the system, then its hardware must also be tested. Several
more sweep times are chosen to test: fast sweep times at multiples of the digitizer's clock rate,
worst-case resolution errors, and long sample rates.

Description
This test measures the accuracy of the EMIM's external bias output current, which is
available for externally biasing a microwave mixer. The mixer bias current is measured over
its full range by comparing the programmed bias current to the voltage developed across a 50
termination by this current.
Current is stepped in 10 A increments over the 010 to +10 mA range while the actual
current is measured by reading the voltage developed across the 50 termination with a
voltmeter.
Due to the small currents used, the resistance of the termination must be
measured using the four-wire ohm technique.

Setup B: Connect the general source output to the IF INPUT of the HP 70907A external
mixer interface module (EMIM). Connect the sensor module to the 321.4 MHz OUT of the
EMIM.
Description
This test measures the amplitude variation of the internal calibration source over its tuning
range referenced to a 035 dBm signal applied to the IF INPUT of the EMIM.
The general source is set to a frequency of 321.4 MHz and an amplitude of 035 dBm. The
amplitude of the general source output is measured by the measuring receiver. The cables
that are needed to connect the source to the EMIM must be included so that any losses may
be accounted for and calibrated out.
The amplitude of the EMIM output is measured to establish its gain. The internal calibration
source of the EMIM is then stepped over its frequency range in 5 kHz increments. At
each frequency increment, the actual frequency is measured by the measuring receiver; the
frequency of the internal calibration source cannot be set directly.
The internal calibration source is tuned over its range while the measuring receiver measures
the amplitude of the EMIM 321.4 MHz OUT. This data is then normalized to the 035 dBm
level previously set.
Note that the internal calibration source is actually changing frequency. The tuning is not
symmetrical about the 321.4 MHz nominal center and requires tuning 630 kHz of this center.

Description
This test measures amplitude variation of the HP 71300A millimeter spectrum analyzer from
18 to 26 GHz. The microwave power sensor is selected and the system is interrogated for
an IF section. This step allows an optimum resolution bandwidth to be used to minimize
measurement errors due to log delity. The signal is centered on the display using a span that
is ve times greater than the resolution bandwidth. Marker amplitude is measured at 100
MHz increments and compared with the power meter measurement, which has been corrected
for directional-coupler coupling factor. The system conversion loss is set to 0 dB so that the
conversion loss being measured is that of the external mixer when used with the HP 71300A
system. The frequency response is then one-half of the dierence between the maximum and
minimum values measured.

Description
Frequency readout accuracy is measured by comparing the marker frequency of the system
to the frequency input to the system by the microwave source. A 100:1 span/resolution
bandwidth ratio is needed to reduce the errors associated with the marker resolution. The
modular system is interrogated for an IF section. If only the HP 70903A IF section is present,
the minimum span that can be used is 10 MHz. If an external 100 MHz reference is connected
to the HP 70900 local oscillator, the external reference must be disconnected to allow the
accuracy of the test to be based only on the accuracy of the internal reference.
The number of frequencies and spans to be used in testing is determined by the test mode. At
least one fractional N span and one lock-and-roll span are tested.

Description
Frequency span accuracy is measured by comparing the marker frequency of the system
at several points on the display to the frequency of the microwave source. The deviation
between marker frequency and microwave source frequency is the absolute error. The
maximum frequency span error is calculated by taking the dierence between the maximum
and minimum absolute errors. A 100:1 span/resolution-bandwidth ratio is needed to reduce
the errors associated with the marker resolution. The modular system is interrogated for an
IF section. If only the HP 70903A IF section is present, the minimum span that can be used
is 10 MHz. If an external 100 MHz reference is connected to the HP 70900 local oscillator, the
external reference must be disconnected to allow the accuracy of the test to be based only on

Displayed Average Noise Level
Description
This test measures the displayed average noise level of the spectrum-analyzer/external-mixer
system. The displayed average noise level is closely related to sensitivity, which determines the
lowest level signal that may be measured by the IF section.
This measurement is made by sweeping the full 18 GHz to 26 GHz frequency band to
determine the frequency with the highest displayed average noise. The spectrum analyzer is
set to zero span at this frequency, the resolution bandwidth is set to 1 kHz (100 kHz with
HP 70903A IF section), and the sample detector is enabled. Sweep time is determined by
auto-correlation, and sweeps are taken until the displayed average noise level is known to
be accurate to 0.5 dB. If setup B is used, the source frequency is set to 15 GHz and the
amplitude to 0120 dBm.

Residual Responses
Description
This test measures residual responses that are on the display when there is no input signal. A
residual response results when mixing of at least two of the DUT's internal signals produces a
product at one of the DUT's intermediate frequencies.
The DUT is calibrated, if necessary. If setup B is used, the test terminates the external mixer
by setting the source to 15 GHz, 0120 dBm.
Maximum DUT sensitivity results with the internal attenuator at 0 dB and an IF gain of
50 dB. The test then measures responses at possible residual frequencies. The test frequencies
are in-band results of calculations involving up to 50 harmonics of the DUT's xed LO
frequencies (300 MHz and 18.4 MHz) and the intermediate frequencies (321.4 MHz, 21.4 MHz,
and 3.0 MHz).
Uncertainties
The following characteristics contribute to uncertainties:
DUT calibrator error
DUT marker amplitude resolution
DUT step gain error
DUT resolution bandwidth switching
DUT attenuator switching errors
DUT log delity
The RSS total of these uncertainties is calculated for each measurement.
Test Mode
This test is run in Limited Cal mode.

Connect the general source to the input of the power splitter. Connect one output of the
power splitter to the IF INPUT of the HP 70907A external mixer interface module (EMIM).
To the remaining output of the power splitter, connect the sensor module from the measuring
receiver.
Description
This test measures the relative on-screen log scale delity (that is, the display CRT's upper
eight divisions for the HP 70903A, or upper nine divisions for the HP 70902A).
The IF section is set to 100 kHz (HP 70903A) or 1 kHz (HP 70902A) resolution bandwidth,
300 Hz video bandwidth, and sample detection. The HP 71300A millimeter spectrum analyzer
acts as a xed-tuned 321.4 MHz receiver, so the span is set to 0 Hz. The reference is set
to provide maximum on-screen dynamic range. The general source frequency is adjusted
to center the signal in the IF passband, and the general source amplitude is adjusted to
set the signal at the reference level. The measuring receiver measures the general source
amplitude. The dierence between the measuring receiver reading and marker amplitude
readout establishes a top-screen reference.
The general source amplitude is decreased in 1 dB increments (2 dB in Limited Cal and All
Tests modes) until the signal is 75 to 90 dB below
top-screen. The actual level depends on the IF being tested and the test mode. In the
last 20 dB of the log range, the sweep time is increased to lessen the eects of the reduced
signal-to-noise ratio. Once all measurements have been made, the data is normalized to 010
dB of top-screen to account for the small amount of gain compression in the upper 10 dB of
display range.
If the HP 70700A digitizer is in the system, the test is run again with the digitizer selected.

Connect the general source to the input of the power splitter. Connect one output connector
of the power splitter to the IF INPUT of the HP 70907A external mixer interface module
(EMIM). To the remaining output connector of the power splitter, connect the sensor module
from the measuring receiver.
Description
This test measures the resolution bandwidth switching variation by taking a reference
amplitude reading in 1 kHz (HP 70902A) or 300 kHz (HP 70903A) resolution bandwidth, then
comparing the IF section resolution-bandwidth amplitude (from 300 Hz to 300 kHz) to this
reference. During this measurement, the video bandwidth is set at 300 Hz (used during the
calibration of the IF section) to eliminate any amplitude shift caused by video bandwidth
switching.
The 3 dB and 60 dB bandwidths are determined by the following algorithm: The resolution
bandwidths are stepped in a 1, 3, 10 sequence from 300 Hz to 300 kHz (HP 70902A) or
100 kHz to 3 MHz (HP 70903A), the general source frequency is adjusted to peak the signal
in each bandwidth, and the marker amplitude is read by taking the mean of the trace points.
The mean is used as a reference amplitude.
The general source amplitude is stepped down 3 dB (or 60 dB) to establish a reference marker
amplitude on the display. The general source amplitude is then returned to the original level
and the frequency is adjusted until the lower 3 dB (or 60 dB) point is found. This procedure
is repeated for the upper 3 dB (or 60 dB) point. The 3 dB (or 60 dB) bandwidth is the
dierence between the upper and lower frequencies. The selectivity (shape factor) is the ratio
of the 60 dB bandwidth divided by the 3 dB bandwidth.

and 3 MHz (HP 70903A), are tested.
In Case of Failure
Note
The switching specication is primarily determined by the preceding

that it passes before assuming that the resolution bandwidths are out of

Description
This test measures the internal IF step gain of the IF section. The IF step gain is controlled
by the reference level, attenuator setting, and calibration amplitude corrections. The IF
section is set to zero span and the EMIM attenuator is set to 0 dB. The reference level is
adjusted for the highest level that produces an IF gain of 0 dB with an EMIM attenuator
setting of 0 dB. The general source frequency is adjusted to center the signal in the IF
passband. Reference readings are taken using the measuring receiver and the voltmeter. The
reference level and general source amplitude are then decreased in 10 dB increments until
50 dB of IF gain is achieved. The dierences between the measuring receiver readings and the
voltmeter readings is the IF gain variation.

Description
This test measures image responses at osets of two times the 3 MHz and 21.4 MHz IFs.
The DUT is calibrated, if necessary, and a check is made for proper
test-equipment connections. Because measurements are performed in zero span, the sweep
time is set to a minimum value as determined by the autocorrelation theorem. Maximum
on-screen dynamic range is found by adjusting the reference level. Adjustment of the general
source frequency peaks the signal in the selected resolution bandwidth. Adjustment of the
general source amplitude places the signal at the top-line reference level. After the IF has
settled, the test measures the image response amplitude.

Measurement Uncertainty
Introduction
The program combines individual measurement uncertainties to arrive at total uncertainty,
and that establishes a range of ambiguous results and a boundary beyond which results are
denitely unacceptable. Total uncertainty multiplied by a measurement uncertainty coecient
combines with specication limits to determine the test limits, which determine acceptable
system performance. The HP performance tests are shipped with the coecient set to zero
in every test, thus setting test limits at the specication range limits. Figure A-1 illustrates
acceptable performance with a zero coecient. The last section of this appendix tells how to
change the measurement uncertainty coecient on a test-by-test basis.

Combining Individual Uncertainties
Individual measurement uncertainties vary with test equipment and measurement techniques.
Either of two methods of combining uncertainties produces a total uncertainties gure:
Worst-Case Sum, or Root Sum of the Squares (RSS).
Worst-Case Sum denes boundaries of total uncertainty without providing a specic estimate.
RSS is an accurate and statistically signicant estimate. Where appropriate, the tests use
RSS.
Worst Case analysis sums absolute magnitudes of individual measurement uncertainties to
produce the largest possible value.
jU1 j + jU2j + jU3 j + ::: + jUn j
RSS uncertainty utilizes the fact that individual uncertainties are independent of each other
and can therefore be combined as random variables.

Measurement Uncertainty
Combining Uncertainty and Specification
Using the instructions in this section, a qualied person can change the measurement
uncertainty coecient on a test-by-test basis.
On Test Disk 1 there is an ASCII le named TEST LIST, which contains a section for every
test applicable to the particular system software package. (Use GET and SAVE to retrieve
and store ASCII les.) Each section has a line labeled FLAGS; in other words, there is a
FLAGS line for every test. The number after the second comma in the FLAGS line is the
measurement uncertainty coecient. To change the coecient, modify this number. A
negative coecient tightens the test limit. The absolute coecient times total measurement
uncertainty tightens or loosens test limits. For example, a coecient of 00.5 tightens the test
limit by the uncertainty times 0.5.
Note
When the System Performance Test program is verifying warranted
performance, the uncertainty coecient must be zero for all tests.
