Preface
Related Manuals
This is the Performance Verification for the R SA3408B 8 GHz Real-Time
Spectrum Analyzer. It contains procedures suitable for determining that the
analyzer functions, is adjusted properly, and meets the performance characteristicsaswarranted.
This document also contains the specifications for the RSA3408B analyzer.
The following documents relate to the use or service of the analyzer:
H The RSA3408B User Manual describes how to operate your analyzer.
H The RSA3000B Series Programmer Manual describes how to use a computer
to control the analyzer through the GPIB interface.
H The RSA3408B Service Manual provides information for maintaining and
servicing your analyzer to the module level.

Performance Verification
Performance Verification Procedures
Two types of Performance Verification procedures can be performed on this
product; Brief Procedures and Performance Tests. You may not need to perform
all of these procedures, depending on what you want to accomplish.
H To rapidly confirm that the analyzer functions properly and was adjusted
properly, do the brief procedures under Functional Tests and Diagnostics,
which begin on page 1--3.
Advantages: These procedures are quick to do, require no external
equipment or signal sources, and perform functional and accuracy testing to
provide high confidence that the analyzer will perform properly. They can be
used as a quick check before making a series of important measurements.
H If more extensive confirmation of performance is desired, do the Perfor-
mance Tests, beginning on page 1--9, after doing the Functional Tests and
Diagnostics.
Advantages: These procedures add direct checking of warranted specifications.
Disadvantages: They require more time to perform and suitable test
equipment is required. (Refer to Required Equipment on page 1--11.)

Conventions
Throughout these procedures, the following conventions apply:
H Each test procedure uses the following general format:
Title of Test
Equipment Required
Prerequisites
Procedure
H Each procedure consists of as many steps, substeps, and subparts as required
to do the test. Steps, substeps, and subparts are sequenced as follows:
1. First Step
a. First Substep
H First Subpart
H Second Subpart
b. Second Substep
2. Second Step
H Instructions for menu selection follow this format:
Front Panel Key → Side Menu Key → Submenu Key.
For example, “Press Mode: Demod → Digital Demod → Constellation”.
“Mode: Demod” indicates the Demod key in the Mode menu area on the
front panel.
H In steps and substeps, the lead-in statement in italics tells you what to do,
and t he instructions that follow tell you how to do it.
The example step below is telling you to set the analyzer controls by
pressing the specified key sequence.
Set the RSA3408B analyzer controls:
Press Mode: Demod → Digital Demod → Constellation.
STOP. The symbol at the left is accompanied by information you must read to do
the procedure properly.

Brief Procedures
The Functional Tests use the internal calibration signal as a test-signal source for
further verifying that the analyzer functions properly.
The Diagnostics use internal routines to verify that the instrument functions
properly and passes the internal circuit t ests.
The following section provides the details.

Performance Tests
This section contains procedures for checking that the RSA3408B 8 GHz
Real-Time Spectrum Analyzer performs as warranted.
The procedures are arranged in four logical groupings:
H Frequency Checks
H Noise Sideband Checks
H Amplitude C hecks
H Spurious Response Checks
They check all the characteristics that are designated as checked in Chapter 2,
Specification. (The characteristics that are checked appear with the n symbol in
the Characteristics column in Chapter 2.) You can use the form at the end of this
section as a test record.
Read Performance Verification Procedures on pages 1-1 and 1-2. Also, if you are
not familiar with operating this analyzer, read the RSA3408B User Manual
before doing any of these procedures.
STOP. These procedures extend the confidence level provided by the basic
procedures described on page 1--3. Perform the basic procedures first and then
perform the follow ing procedures if desired.
