Preface
This manual contains the specifications and performance verification procedures
for the DSA8300 Digital Serial Analyzer, the extender cables, and the modules
that can be installed in this instrument (except the 80A03 module).
NOTE. The 80A03 instruction manual contains its own specifications and
servicing information.
Read this preface to learn how this manual is structured, what conventions it uses,
and where you can find other information related to this product.
Manual Structure
This manual is divided into chapters that are made up of related subordinate
topics. These topics can be cross referenced as sections.
Be sure to read the introductions to all procedures. These introductions provide
important information needed to do the service correctly, safely, and efficiently.
Manual Conventions
This manual uses certain conventions that you should become familiar with
before attempting service.
Modules Throughout this manual, the term module appears. A module is composed of
electrical and mechanical assemblies, circuit cards, interconnecting cables, and a
user-accessible front panel. References to a module are different than references to
products such as “Sampling modules”, “Phase Reference modules”, or “Accessory
modules”, which are products installed in the instrument compartments or on
extender cables.
Safety Symbols and terms related to safety appear in the General Safety Summary found
at the beginning of this manual.

Performance Verification Procedures
Two types of Performance Verification procedures can be performed on this
product: Brief Procedures and the more extensive Performance Tests.Youmay
not need to perform all of these procedures, depending on what you want to
accomplish:
To rapidly confirm that the instrument functions and was adjusted properly,
just do the Perform the Diagnostics and Perform the Compensation
procedures. (See page 2, Functional Test Procedures.)
Advantages: These procedures are quick to do, require no external equipment
or signal sources, and perform extensive functional and accuracy testing to
provide high confidence that the instrument will perform properly. They can
be used as a quick check before making a series of important measurements.
To further check functionality, first do the procedures just mentioned, and
then do the procedure Perform the Functional Tests,.(Seepage2,Functional
Test Procedures.)
Advantages: These procedures require minimal additional time to perform,
require no additional equipment other than connection hardware, and more
completely test the internal hardware of the instrument. They can be used to
quickly determine if the instrument is suitable for putting into service, such
as when it is first received.
If more extensive confirmation of performance is desired, do the Performance
Tests after doing the procedures just referenced. (See page 15, Performance
Tests.)
Advantages: These procedures add direct checking of warranted
specifications. They require more time to perform and suitable test equipment
is required. (See page 17, Equipment Required.)
If you are not familiar with operating this instrument, refer to the online help or
the user information supplied with the instruments.

Functional Test Procedures
Functional Test Procedures
There are three procedures in this section that provide a quick way to confirm
basic functionality and proper adjustment of the DSA8300:
(See page 2, Instrument Diagnostics.)
(See page 3, Instrument and Module Compensation.)
(See page 6, Instrument Functional Tests.)
These procedures require little or no test equipment. For information on when to
use these procedures, refer to Performance Verification Procedures. (See page 1,
Performance Verification Procedures.)
Instrument Diagnostics
The following steps run the internal routines that confirm basic functionality
and proper adjustment.
Equipment required None
Prerequisites Install all sampling modules to be diagnosed: see module user
manual for installation instructions.
Power on the instrument and wait 20 minutes (warm-up period)
before doing this procedure.
