Preface
This is the service manual for the DSA8300 Digital Serial Analyzer and the
modules that install in the instrument (except for 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,
andwhereyoucanfind other information related to servicing this product. Read
the Introduction following this preface for safety and other important background
information needed before servicing this product.
Manual Structure
This manual is divided into sections, which 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 beginning service.
Assemblies and Modules Throughout this manual, the term assembly appears. An assembly is composed
of electrical and mechanical assemblies, circuit cards, interconnecting cables,
and a user-accessible front panel. References to an assembly are different
than references to a module such as “Sampling modules,” “Phase Reference
modules,” or “Accessory modules,” which are products installed in the instrument
compartments.
Replaceable Parts This manual refers to any field-replaceable assembly or mechanical part by its
name or generically as a replaceable part. In general, a replaceable part is any
circuit board or assembly, such as a hard disk drive, or a mechanical part, such as
I/O port connectors, that is listed in the replaceable parts list.
Safety Symbols and terms related to safety appear in the General Safety Summary and
the Service Safety Summary found at the beginning of this manual.
