Chapter 1
Installation and Setup
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

Front and Rear Panel Features
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.
Chapter 2
29
Front and Rear Panel Features
Key Overview
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.
The arrow keys located below the analyzer display (sometimes referred to as Tab keys) can
be used to navigate within tables, for example the Limit-Line table. These keys are used to
move between rows. The Left-arrow key moves up, while the right-arrow key moves down.
While navigating through the table, the cursor (inverse video highlight) stays in the same
column. Navigating left or right in the table is accomplished by choosing the desired field
using the front-panel keys.

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/Programmer’s manual.
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

Improving Frequency Accuracy
10.While not all of the zeros following the decimal in the active function block are
significant, the numbers after the decimal in the marker annotation (upper-right
corner of screen) are significant. To increase the accuracy of the frequency reading in
the marker annotation, turn on the frequency count function.
a. Press Mkr Fctn.
• The Marker Fctn softkeys appear.
b. Press Marker Count.
• The Marker Count softkeys appear.
11.Note softkey Marker Count On Off. If Off is underlined, press the softkey to toggle
marker count on.
As shown in Figure 3-5:
• The marker annotation changes from Mkr1 to Cntr1.
• The displayed resolution in the marker annotation improves.
NOTE
When you use the frequency count function, if the ratio of the resolution
bandwidth to the span is less than 0.002, the following message
appears on the display: Freq Count: Reduce Span/RBW ratio
This indicates that the resolution bandwidth is too narrow.
12.Press Marker ➞, Mkr ➞ CF to move the 10 MHz peak to the center of the display.
Valid Marker Count Range
13.Move the marker down the skirt of the 10 MHz peak. Note that although the readout
in the active function changes, as long as the marker is at least 26 dB above the noise,
the counted value (upper-right corner of display) does not change (see Figure 3-6). For
an accurate count, the marker does not have to be at the exact peak.
NOTE
Marker count functions properly only on CW signals or discrete peaks.
For a valid reading, the marker must be ≥26 dB above the noise.
14.Press BW/Avg, Res BW, then enter a new value. This action makes the resolution
bandwidth the active function and allows you to experiment with different resolution
bandwidth (RBW) values.
15.Press Marker, Off to turn the marker off.

Viewing Catalogs and Saving Files
The analyzer stores and retrieves data similarly to the way that a personal computer (PC)
does: both have internal storage and a floppy disk drive. While a PC has an internal drive,
the analyzer’s internal storage is nonvolatile (flash) memory, which acts as an internal
drive. As with a PC, both the internal storage and the floppy disk drive have directory and
sub-directory capability; in the analyzer, directories and subdirectories are called catalogs.
This chapter tells you how to:
• locate catalogs and view files, on page 45.
• save a file, on page 48.
For more information on catalogs and files, see the Measurement guide.

This chapter describes how to use the functions located under the front-panel File key.
Data storage and retrieval are handled similarly to that of personal computers (PCs). Like
PCs, these analyzers include an internal storage drive and a floppy disk drive, both of
which have directory and sub-directory capability.
You will learn how to do all of the following:
•
•
•
•
•
•
•
locate and view files in the catalog
format a floppy disk
save a file
load a file
rename a file
copy a file
delete a file
NOTE
The display examples in this book are made using various analyzer models,
you may see some variations depending upon your analyzer.
Locating and viewing files in the catalog
Techniques for locating files and directories are consistent throughout the various file
menu functions. Although this section provides specific information about navigation in
the catalog, you may wish to refer back to this section when performing other operations of
the file menu.
The analyzer has three default catalogs (directories):
• State, which stores analyzer settings.
• Trace, which stores trace information.
• Screen, which stores screen captures of the display in .gif or .wmf format.
NOTE
Chapter 4
Trace files are not bitmap files. Files saved as Trace cannot be imported into
other applications or converted. If you require the use of other applications,
for example Microsoft Word or Microsoft Excel, be sure to save your files as
.gif or .wmf formats using Screen for your file Type.

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.
46

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 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

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.

❏ If other equipment, cables, and connectors are being used with your spectrum analyzer,
make sure they are connected properly and operating correctly.
❏ Review the measurement procedures being performed when the problem first appeared.
Are all of the settings correct?
❏ If the analyzer is not functioning as expected, return the analyzer to a known state by
pressing Preset, and Factory Preset (if displayed).
NOTE
Some analyzer settings are not affected by a Preset. If you wish to reset the
analyzer configuration to the state it was in when it was originally sent from
the factory, press System, Power On/Preset, Preset Type, Factory. Then press the
green Preset key on the front panel.
❏ Is the measurement being performed, and the results that are expected, within the
specifications and capabilities of the analyzer? Refer to the Specifications guide for your
analyzer.
❏ If the analyzer is not communicating via the LAN connection, check for the presence of
blinking yellow LEDs on the rear panel LAN connector. If the Rx (receive) LED is not
blinking, check the LAN cable and LAN integrity.
NOTE
The analyzer must be powered on with the LAN already connected in order to
recognize the LAN port.
❏ To meet specifications, the analyzer must be aligned. Either the Auto Align (On) feature
must be selected (press System, Alignments, Auto Align, On), or the analyzer must be
manually aligned at least once every 24 hours, or whenever the temperature changes
more than 3°C. When Auto Align, On is selected, the AA screen annotation appears on
the left edge of the display.

Service Tag
When you are returning an analyzer to Agilent Technologies for service, fill out and attach
one of the blue service tags provided at the end of this chapter. Please be as specific as
possible about the problem. If you have recorded any error messages that appeared on the
display, have completed a functional test, or have any other specific data on the
performance of your analyzer, please include a copy of this information.
Original Packaging
Before shipping, pack the unit in the original factory packaging materials if they are
available. If the original materials were not retained, see "Other Packaging" (below).
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.

Chapter 6

Returning an Analyzer for Service
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.
7. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to assure careful
handling.
8. Retain copies of all shipping papers.
