Preface
Manual Structure
This is the service manual for the RSA2203A and RSA2208A Real-Time
Spectrum Analyzers. The manual contains information needed to service the
analyzer to the module level.
This manual is divided into sections, such as Specifications and Theory of
Operation. Further, some sections are divided into subsections, such as
Product Description and Removal and Installation Procedures.
Sections containing procedures also contain introductions to those procedures.
Be sure to read these introductions because they provide information needed to
do the service correctly and efficiently. The manual section name and a brief
description of each is given below.
H Specifications contains a description of the analyzer and the applicable
characteristics.
H Operating Information contains a statement referring you to the RSA2203A
and RSA2208A User Manual.
H Theory of Operation contains circuit descriptions that support service to the
module level.
H Performance Verification contains procedures for confirming that the
analyzer functions properly and meets warranted limits.
H Adjustment Procedures contains procedures for adjusting the analyzer to
meet warranted limits.
H Maintenance contains information and procedures for performing preventive
and corrective maintenance of the analyzer. These instructions include
cleaning, module removal and installation, and fault isolation to the module.
H Options contains a statement referring you to the RSA2203A and RSA2208A
User Manual.
H Electrical Parts List contains a statement referring you to Mechanical Parts
List, where both electrical and mechanical modules are listed.
H Diagrams contains a block diagram and an interconnection diagram.
H Mechanical Parts List includes a table of all replaceable modules, their
descriptions, and their Tektronix part numbers.

Preface
Manual Conventions
This manual uses certain conventions that you should become familiar with.
Some sections of the manual contain procedures for you to perform. To keep
those instructions clear and consistent, this m anual uses the following conventions:
H Names of front panel controls and menus appear in the same case (initial
capitals, all uppercase, etc.) in the manual as is used on the analyzer front
panel and menus. Front panel names are all upper-case letters; for example,
SPAN, TRIG, and SELECT.
H Instruction steps are numbered unless there is only one step.
Modules
Safety
Throughout this manual, any replaceable component, assembly, or part of the
analyzer is referred to generically as a module. In general, a module is an
assembly (like a circuit board), rather than a component (like a resistor or an
integrated circuit). Sometimes a single component is a module; for example, the
chassis of the analyzer is a module.
Symbols and terms related to safety appear in the Safety Summary near the
beginning of this manual.
Finding Other Information
Other documentation for the RSA2203A and RSA2208A analyzers includes:
H The RSA2203A and RSA2208A User Manual contains a tutorial to quickly
H The RSA2203A and RSA2208A Programmer Manual explains how to use the
describe how to operate the analyzer. It also includes an in-depth discussion
on how to more completely use the analyzer features.

RSA2203A & RSA2208A Service Manual
Introduction
This manual contains information needed to properly service the RSA2203A and
RSA2208A Real-Time Spectrum Analyzers as well as general information
critical to safe and effective servicing.
To prevent personal injury or damage to the analyzer, consider the following
before attempting service:
H The procedures in this manual should be performed only by a qualified
service person.
H Read the General Safety Summary and the Service Safety Summary,
beginning on page ix.
H Read Preparation for Use in section 2, Operating Information.
When using this manual for servicing, be sure to follow all warnings, cautions,
and notes.
Performance Check Interval
Strategy for Servicing
Generally, the performance check described in section 4, Performance Verification, should be done every 12 months. In addition, performance check is
recommended after module replacement.
If the analyzer does not meet performance criteria, repair is necessary.
Throughout this manual, the term “module” refers to any field-replaceable
component, assembly, or part of the analyzer.
This manual contains all the information needed for periodic maintenance of the
analyzer. (Examples of such information are procedures for checking performance.)
Further, it contains all information for corrective maintenance down to the
module level. To isolate a failure to a module, use the fault isolation procedures
found in Troubleshooting, part of section 6, Maintenance. To remove and replace
any failed module, follow the instructions in Removal and Installation Proce-
dures, also part of section 6. After isolating a faulty module, replace it with a
fully-tested module obtained from the factory. Section 10, Mechanical Parts
List, contains part number and ordering information for all replaceable modules.
