AC Power Cord
The analyzer is equipped with a three-wire power cord, in accordance with international safety
standards. This cable grounds the analyzer cabinet when connected to an appropriate power line outlet.
The cable appropriate to the original shipping location is included with the analyzer.
Various AC power cables are available that are unique to specific geographic areas. You can order
additional AC power cables for use in different areas. AC Power Cords, on page 12 lists the available AC
power cables, illustrates the plug configurations, and identifies the geographic area in which each cable
is appropriate.
NOTE
The front panel switch is a standby switch only; it is not a LINE switch (power
disconnecting device).
WARNING
Install the product so that the detachable power cord is readily identifiable and
easily reached by the operator. The detachable power cord is the product
disconnecting device. It disconnects the mains circuits from the mains supply before
other parts of the product. The front panel switch is only a standby switch and is not
a LINE switch. Alternatively, an externally installed switch or circuit breaker
(which is readily identifiable and is easily reached by the operator) may be used as a
disconnecting device.
CAUTION
Always use the three-prong AC power cord supplied with this product. Failure to ensure
adequate earth grounding by not using this cord can cause product damage.
CAUTION
This analyzer has autoranging line voltage input. Be sure the supply voltage is within the
specified range. (Refer to the specifications guide for your analyzer.)

Installation and Setup
Running Internal Alignments
Running Internal Alignments
Each time the analyzer is powered on, the internal alignment routine runs automatically.
The analyzer was shipped from the factory with the Alignments mode set to Auto,
Align All.
NOTE
When the Alignment routine runs, you will hear the attenuator settings changing, which
generates noise. This is not an indication of trouble.
Manually Performing an Alignment
If the analyzer is an Agilent Technologies E7402A, E7403A, E7404A, or E7405A, connect a BNC cable
from the AMPTD REF OUT to INPUT 50 Ω using an adapter. After a 5 minute warm-up, press System,
Alignments, Align Now, All.
NOTE
It is normal to hear clicking when the Auto Alignment function is on. During the interval
between sweeps, portions of the analyzer’s circuitry are realigned. Some of the circuitry
is controlled by relays. It is the rapid switching of these relays between sweeps which
causes the clicking sound. Under normal operation, these relays will last over 50 years.
To eliminate the clicking sound, turn off the automatic alignment. (See the Alignments
key description in your User’s guide.”) With Auto Align turned off, however, the Align
Now All function should be performed periodically. For more information on how often
to perform Align Now All when the Auto Alignment function is off, refer to the
appropriate “Specifications and Characteristics” chapter in your specifications guide.
If Auto Align, Off is selected, refer to the Specifications guide for the conditions required to maintain
calibration.

Printer Setup and Operation
Interconnection and Setup
1. Turn off the printer and the analyzer.
2. Connect the printer to the analyzer parallel I/O interface connector using an IEEE 1284 compliant
parallel printer cable.
3. If appropriate, configure your printer using configuration menus or switches. Refer to your printer’s
documentation for more specific information on configuring your printer.
4. Turn on the analyzer and printer.
5. Press Print Setup on the front panel and then press the Printer Type menu key. Printer Type
accesses the following keys:
None
None disables the analyzer from attempting to print to a printer. This is the
appropriate setting if no printer is connected to the analyzer.
Custom
Custom allows you to access the Define Custom menu keys. The Define Custom
menu keys allow you to specify printer characteristics such as PCL Level and
printer color capability.
Auto
Auto enables the analyzer to automatically attempt to identify the connected
printer when the Print key is pressed or when Printer Type is set to Auto.
6. Press Printer Type to access the Printer Type menu keys. Press Auto to make the analyzer attempt to
identify the connected printer. When you press Auto, the analyzer will respond in one of the three
following ways:
•
The Print Setup menu will be displayed with the Auto key selected and no new message will be
displayed in the display status line. This indicates that the analyzer has successfully identified the
connected printer and no further setup is required. As long as Auto remains selected in the Printer
Type menu, the analyzer will attempt to identify the printer when the front panel Print key is
pressed. The selected printer will be displayed by pressing System, More 1 of 3, Show System.
•
The Print Setup menu will be displayed with the Custom key selected and one of the following
diagnostic messages will be displayed in the display status line:
Unknown printer, Define Custom to set up printer
No printer response, Define Custom to set up printer
Invalid printer response, Define Custom to set up printer
This indicates that the analyzer was unable to automatically identify the connected printer, and
Custom has been selected in the Printer Type menu. Press Print Setup, Define Custom to select
specific printer characteristics such as the printer language (PCL3 or PCL5) and color printing
capability. Once you have set these characteristics to match those of your connected printer, the
printer setup process is complete. As long as Custom remains selected in the Printer Type menu,
the analyzer will not attempt to automatically identify the connected printer when the front panel
Print key is pressed.

Protecting Against Electrostatic Discharge
Protecting Against Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components (the possibility of unseen
damage caused by ESD is present whenever components are transported, stored, or used).
Test Equipment and ESD
To help reduce ESD damage that can occur while using test equipment:
•
Before connecting any coaxial cable to an analyzer connector for the first time each day, momentarily
short the center and outer conductors of the cable together.
•
Personnel should be grounded with a 1 MΩ resistor-isolated wrist-strap before touching the center
pin of any connector and before removing any assembly from the analyzer.
•
Be sure that all instruments are properly earth-grounded to prevent build-up of static charge.
WARNING
Do not use these first three techniques when working on circuitry with a voltage
potential greater than 500 volts.
•
Perform work on all components or assemblies at a static-safe workstation.
•
Keep static-generating materials at least one meter away from all components.
•
Store or transport components in static-shielding containers.
•
Always handle printed circuit board assemblies by the edges. This reduces the possibility of ESD
damage to components and prevent contamination of exposed plating.
For information on ordering static-safe accessories, see “Accessories” on page 73.
Additional Information about ESD
For more information about ESD and how to prevent ESD damage, contact the Electrostatic Discharge
Association (http://www.esda.org). The ESD standards developed by this agency are sanctioned by the
American National Standards Institute (ANSI).

Esc. The Esc (escape) key cancels any entry in progress. Esc will abort a print (if one
is in progress) and clear error messages from the status line at the bottom of the
display. It also clears input and tracking generator overload conditions.
3
Menu keys are the unlabeled keys next to the screen. The menu key labels are the
annotation on the screen next to the unlabeled keys. Most of the labeled keys on the
analyzer front panel (also called front-panel keys) access menus of keys having
related functions.
4
FREQUENCY Channel, SPAN X Scale, and AMPLITUDE Y Scale are the three large
keys that activate the primary analyzer functions and access menus of related
functions. The secondary labels on these keys (Channel, X Scale, and Y Scale) are
used in some measurements.
24
Chapter 2
Front and Rear Panel Features
Front Panel Overview
5
CONTROL functions access menus that allow you to adjust the resolution bandwidth,
adjust the sweep time, and control the analyzer display. They also set other analyzer
parameters needed for making measurements.
6
MEASURE accesses a menu of keys that automate some common analyzer
measurements. Once a measurement is running, Meas Setup accesses additional
menu keys for defining your measurement. Meas Control and Restart access
additional measurement control functions.
7
SYSTEM functions affect the state of the entire analyzer.
Various setup and alignment routines are accessed with the System key.
The green Preset key resets the analyzer to a known state.
The File key menu allows you to save and load setups, traces, states, limit-line
tables, screens, signal lists, reports, and amplitude correction factors to or from
analyzer memory or the floppy disk drive. The Save key immediately executes the
Save Now function defined under File in your User’s guide.
The Print Setup menu keys allow you to configure hardcopy outputs. The Print
key immediately sends hardcopy data to the printer. See your User’s guide for
more details.
8
MARKER functions control the markers, read out frequencies and amplitudes along
the analyzer trace, automatically locate the signals of highest amplitude, and access
functions like Marker Noise and Band Power.
9
The Media Door on the right side of the front panel accesses the 3.5 inch disk drive
and the Earphone connector. The earphone connector provides a connection for an
earphone jack which bypasses the internal speaker.
10
The Data Control Keys, which include the step keys, knob, and numeric keypad,
allow you to change the numeric value of an active function such as center frequency,
start frequency, resolution bandwidth, and marker position.
The data controls will change the active function in a manner prescribed by that
function. For example, you can change center frequency in fine steps with the knob, in
discrete steps with the step keys, or to an exact (1 Hz resolution) value with the
numeric keypad.
The Knob provides fine incremental changes of functions such as center
frequency, reference level, and marker position. Clockwise rotation of the knob
increases values. The extent of alteration is determined by the size of the
measurement range. The speed at which the knob is turned affects the rate at which
the values are changed.
Chapter 2
25
Front and Rear Panel Features
Front Panel Overview
For slow sweeps, the analyzer uses a smooth panning feature which is designed to
move the trace display to the latest function value as the knob is turned. When
center, stop or, start frequency or reference level is adjusted, the signal will shift
right or left or up or down with the rotation of the knob before a new sweep is
actually taken. An asterisk is placed in the message block (the upper right-hand
corner of the analyzer display) to indicate that the data on the screen does not
reflect data at the current setting.
The Numeric Keypad allows entry of exact values for many of the analyzer
functions. You may include a decimal point in the number portion. If not, the
decimal point is placed at the end of the number.
Numeric entries must be terminated with a units key. When a numeric entry is
begun, the menu keys show the units key labels. The units keys change depending
on what the active function is. For example, the units keys for frequency span are
GHz, MHz, kHz, and Hz, whereas the units for reference level are +dBm, −dBm,
mV, μV, and μA.
NOTE
If an entry from the numeric keypad does not coincide with an allowed function value (for
example, that of a 12 MHz bandwidth), the analyzer defaults to the nearest allowable
value.
The Step Keys (⇓ ⇑) increase or decrease the active function value. The step size
depends upon the current analyzer measurement. Each press results in a single step
change. For those parameters with fixed values (resolution bandwidth), the next
value in a sequence is selected each time a step key is pressed. Step size is
predictable (e.g., 10% of span for center frequency) and can be set for some
functions (i.e., center frequency). Out-of-range values or out-of-sequence values
will not occur using these keys.
11
VOLUME. The VOLUME knob adjusts the volume of the internal speaker. The speaker
is turned on and off with the Speaker On Off key in the Det/Demod menu.
12
EXT KEYBOARD. The EXT KEYBOARD connector is a 6-pin mini-DIN connector.
The keyboard can be used to enter screen titles and filenames.
NOTE
To avoid damage to the analyzer, always turn off power before plugging a keyboard into
the analyzer.

SWP OUT provides a voltage ramp corresponding to the sweep of the analyzer (0
V to 10 V).
HI SWP IN (TTL) can be grounded to stop and reset the sweep. Once the sweep has
been stopped, removing the ground will trigger the start of a new sweep.
HI SWP OUT (TTL) is high when the analyzer is sweeping.
AUX VIDEO OUT provides detected video output (before the analog-to-digital
conversion) proportional to vertical deflection of the trace. Output is from 0 V to
1 V. Amplitude-correction factors are not applied to this signal.
AUX IF OUT is a 50 Ω, 21.4 MHz IF output that is the down-converted signal of
the RF input of the analyzer. Amplitude-correction factors are not applied to this
signal. This output is taken after the resolution bandwidth filters and step gains and
before the log amplifier.
NOTE
Only one IF and Sweep Port option (Option A4J or Option AYX) can be installed at a

Standby keys (see Figure 2-2. on page 22, item 21). If the analyzer is on and the
external power is removed and restored within 20 seconds, the analyzer will turn
on. On the other hand, if the external power is removed and restored after 20
seconds, the analyzer will remain in standby regardless of the front panel switch
settings.

Key Overview
Key Overview
The keys labeled FREQUENCY Channel, System, and Marker are all examples of front-panel keys.
The front-panel keys are dark gray, light gray, green, or white in color. Front-panel keys that are white
perform an immediate action rather than bringing up a menu. The only green key is the Preset key,
which performs an analyzer reset (A summary of all front panel keys and their related menu keys can be
found in user’s guide for your analyzer). Pressing most of the dark or light gray front-panel keys accesses
menus of functions that are displayed along the right side of the display. These are called menu keys.
Menu keys list functions other than those accessed directly by the front panel keys. To activate a menu
key function, press the key immediately to the right of the annotation on the screen. The menu keys that
are displayed depend on which front-panel key is pressed and which menu level is enabled.
If a menu key function’s value can be changed, it is called an active function. The function label of the
active function is highlighted after that key has been selected. For example, press AMPLITUDE Y Scale.
This calls up the menu of related amplitude functions. Note the function labeled Ref Level (the default
selected key in the Amplitude menu) is highlighted. Ref Level also appears in the active function block,
indicating that it is the active amplitude function and can now be changed using any of the data entry
controls.
A menu key with On and Off in its label can be used to turn the menu key’s function on or off. To turn
the function on, press the menu key so that On is underlined. To turn the function off, press the menu key
so that Off is underlined. In the manual, when On should be underlined, it will be indicated as Function
(On).
A function with Auto and Man in the label can either be auto-coupled or have its value manually
changed. The value of the function can be changed manually using the numeric keypad, knob, or step
keys. To auto-couple a function, press the menu key so that Auto is underlined. In the manual, when
Auto should be underlined, it will be indicated as Function (Auto).
In some key menus, one key label will always be highlighted to show which key has been selected. For
example, when you press Marker, you will access a menu of keys in which some of the keys are grouped
together by a blue bar on the left side of the menu. The Normal key, which is the Marker menu default
key, will be highlighted. When you press another key within the blue bar region, such as Delta, the
highlight will move to that key to show it has been selected.
In other key menus, one key label will always be highlighted to show which key has been selected but
the menu is immediately exited when a selection is made. For example, when you press the Orientation
key (on the Print Setup menu), it will bring up its own menu of keys. The Portrait key, which is the
Orientation menu default key, will be highlighted. When you press the Landscape key, the highlight
will move to that key to show it has been selected and the screen will return to the Print Setup menu.

Presetting the Spectrum Analyzer
Presetting the Spectrum Analyzer
Preset provides a known starting point for making measurements. The analyzer has three types of
preset:
Factory Preset
Restores the analyzer to its factory-defined state.
User Preset
Restores the analyzer to a user-defined state.
Mode Preset
This type of preset restores the currently selected mode to a known state.
For details, see the User’s guide.
When Preset Type is set to Factory, pressing the green Preset key triggers a factory preset. When
Preset Type is set to User, pressing Preset displays the softkeys Factory Preset, User Preset, and
Mode Preset (if applicable); you then select the preset you want. If Preset Type is set to Mode, but a
personality is not installed, pressing Preset triggers a factory preset.
Creating a User Preset
If you constantly use settings which are not the factory defaults, use the following steps to create a
user-defined preset:
1. Set analyzer parameters as desired.
2. Press System, Power On/Preset, Save User Preset to set the current parameters as the user
preset state.
3. Press Preset to select User in the same softkey menu to enable user preset as an option.
Disabling User Preset

Catalog Menu
1. The entry fields show the parameters for the files viewed. Entry fields that are being modified or are
modifiable are indicated by highlighting (inverse video). Each file menu function has its own unique
set of entry fields pertaining to that function. Below are the fields listed under the catalog key:
a. Name: field states the filename.
b. Show Type: field displays the type of files viewed.
c. Path: field displays the drive and directory location of the files.
2. The directory information box displays the drives, directories, and/or files currently described in the
entry fields. Highlighting a row of information selects that location and updates the entry fields.
There are four column headings in this area of the display. They are described as follows:
a. Name: column states the drive ([-A-] or [-C-]) if at the top level on the drive, directory name,
or filename.
b. Type: column displays the extension of the filename, for example,
.SET, .STA, .TRC. Directories are displayed as DIR and drives have nothing listed under
Type:. They are only designated by the Name: column ([-A-] or [-C-]).
c. Size: column displays the size of the file in bytes.
d. Modified: column displays the date and time the last change occurred.
3. The softkey menu has four options:
a. Type: allows you to choose the type of file you wish to view. (You may view all types by using
Chapter 4

the All key under Type.)
b. Sort: Under the Sort key, you can sort by any of the four columns and you can choose up
(ascending) or down (descending).
c. Dir Up: moves you up one directory level. If you are already at the top level, this key moves you
up to the drive level, displaying the available disk drives.
d. Dir Select: moves you down into the highlighted directory or up into the next level (directory or
drive) if the “. .” under the Name: column is highlighted.
NOTE
Navigation keys: Use the front-panel Step Keys or Knob and the Dir Up or Dir Select
keys to move around in the directory information box.
4. The drive space line shows the number of bytes used on the drive and the number of bytes still free on
the drive.
Creating a directory
Directories and sub-directories can be created on both the A: floppy disc and the internal C: drive. This
allows maximum flexibility in organizing files. For this example, we will create a directory on the C:
drive.
1. Press File, More 1 of 2, Create Dir. Your screen should look similar to Figure 4-1, except the entry
fields will be Dir Name: and Path: and the Heading will read: Directories.
2. Navigate through the file system until the Path: field displays C:\. (Use the Step Keys, Knob, Dir
Up, and/or Dir Select keys.)
3. Press Name and enter the name, “START” using the Alpha Editor. (The numeric keypad is also
available for the filename.) Press Enter (hardkey) when the Dir Name: field contains this directory
title. (Use the Bk Sp hardkey on the front panel to make corrections.)
4. Press Create Dir Now to execute the operation. The message: Creating Directory appears on
the screen. Then the status bar displays: Directory C:\START created.
5. To make a sub-directory, scroll down to the START directory you just created and press Dir Select.
The Path: field should now read: C:\START\. Repeat Steps 3 and 4 above, using a new name. The
status bar now should read: Directory C:\START\new name created.

Formatting a Floppy Disk
You can format a floppy disk in the analyzer. The format is MS-DOS®1. Note that it is not necessary to
format your floppy disk with the analyzer; preformatted disks can be used with the analyzer.
1. Place the 1.44-MB disk you wish to format into the floppy drive (A:\) of the analyzer. Only 1.44-MB
floppy disks are supported by the analyzer. Therefore, 720-kB floppy disks will not work reliably.
2. Access the Format key by pressing File, More, and then Format. The directory information box is
active (highlighted), however, only the floppy disk volume [-A-] is shown on the display.
The directory information box displays all files present on the floppy disk inserted in drive “A:”. If
you have not inserted a disk into drive “A:”, or the disk you are attempting to format has no
pre-existing formatting, the error message: bad, missing, or unformatted disk is displayed
in the status line.
3. Press Format Now. The following message appears in the display window: WARNING: You are
about to destroy ALL data on Volume A:. Press Format Now again to proceed
or any other key to abort. To abort disk format, press any key but Format Now. When a
disk is formatted, all data on the disk is destroyed.
4. Press Format Now a second time to format the disk. You will see the message: Formatting Disk
in the display window. Pressing any other key after receiving the warning in step 3 on page 53, will
abort the formatting process. See Figure 4-2. The format process takes approximately three minutes.

2. Select the type of file you want to save. In this example you are saving a trace; press Type, Trace.
3. Select the trace you wish to save (1, 2, 3, or all traces). In this example you will save trace 3; press
Source (softkey), Trace 3.
4. Select the format you wish to use for saving the trace, either trace plus state (Trace + State) or
comma separated value (CSV). In this example you will save as trace plus state; press Format, Trace
+ State.
5. Enter a filename by pressing Name. The Alpha Editor appears. For this example you will name the
file, “TEST1”. (The numeric keypad is also available for the filename.) Note that the file extension is
always set by the system and for this file type the extension is TRC. You must now press the Enter
(hardkey) to get back to the Save menu.
NOTE
You need to use a filename that does not already exist in the current directory. The
filename is limited to eight characters, alpha (A-Z) or numeric (0-9) in any combination.
The analyzer will not allow you to overwrite an existing file. If you select a filename that
already exists, the status bar will display the message: File already exists. If you
do not choose a filename, the analyzer will automatically generate a name based on the
type of file you are saving (Setup: SETUP, State: STATE, Trace: TRACE, Limits: LIMIT,
Corrections: COREC, Screen: SCREN). It also generates a three digit integer (starting at
000 and extending through 999, remembering the previously saved value through a power
cycle) which it adds to the name, for example: TRACE056.TRC. Also note that this three
digit integer increments upon each attempted save until a unique filename is created,
without regard to the success of the save.
6. The destination for the saved file is shown in the Path: field. In this example, you will select the
path as C:\START\. If the correct location is not listed in the Path: field, change directories as
follows:
a. Press Dir Up or Dir Select and use the step keys or knob, to highlight the desired destination
directory.
b. Press Dir Select and confirm your choice displayed in the Path: field.
7. Press Save Now or Save (hardkey) to save the file to the C:\Start\ location. The message
Saving Now is displayed during this operation. For this example, the status line displays:

NOTE
Install the transportation disk into the floppy drive to reduce the possibility of damage
during transportation. If the original transportation disk is not available, a blank floppy
may be substituted.
Other Packaging
CAUTION
Analyzer damage can result from using packaging materials other than those specified.
Never use styrene pellets in any shape as packaging materials. They do not adequately
cushion the equipment or prevent it from shifting in the carton. They cause equipment
damage by generating static electricity and by lodging in the analyzer louvers, blocking
airflow.
You can repackage the analyzer with commercially available materials, as follows:
1. Attach a completed service tag to the analyzer.
2. Install the transportation disk or a blank floppy disk into the disk drive.
3. Wrap the analyzer in antistatic plastic to reduce the possibility of damage caused by electrostatic
discharge.
4. Use a strong shipping container. The carton must be both large enough and strong enough to
accommodate the analyzer. A double-walled, corrugated cardboard carton with 159 kg (350 lb)
bursting strength is adequate. Allow at least 3 to 4 inches on all sides of the analyzer for packing
material.
5. Surround the equipment with three to four inches of packing material and prevent the equipment
from moving in the carton. If packing foam is not available, the best alternative is S.D.-240 Air
Cap™ from Sealed Air Corporation (Hayward, California, 94545). Air Cap looks like a plastic sheet
filled with 1-1/4 inch air bubbles. Use the pink-colored Air Cap to reduce static electricity. Wrapping
the equipment several times in this material should both protect the equipment and prevent it from
moving in the carton.
6. Seal the shipping container securely with strong nylon adhesive tape.
