Tektronix part number 071-1640-02.

The manual consists of the following sections:

 Specifications contains a description of the arbitrary/function generator and the

characteristics that apply to it.

 Operating Information includes general information and operating

instructions.

 Theory of Operation contains circuit descriptions that support service to the

Preface

Finding Other Information

This manual mainly focuses on the performance verification, troubleshooting and
maintenance of the arbitrary/function generator. See the following list for other
documents supporting the arbitrary/function generator. All documents except
Built-in Help are on the AFG3000 Series Product Documents CD-ROM that
shipped with instrument.

Document name Description

AFG3000 Series Quick Start User Manual A quick reference to major features of the instrument and how they operate. It also provides

several tutorials to familiarize you with basic instrument features.

AFG3000 Series Programmer Manual An encyclopedia of topics that describe the arbitrary/function generator interface and

features, and gives background information on how to use them. It provides Menu
Structures, User Interface, and Programming Information.

product. The help is preinstalled in the instrument.

Manual Conventions

Modules

Safety

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 manual uses the following conventions:

 Front-panel controls and menu names appear in the same case (initial capitals,

all uppercase, and so on) in the manual as is used on the arbitrary/function
generator front-panel and menus. Front-panel labels are all upper case letters
(for example, MENU, SELECT, PULSE GEN, and so on).

 Instruction steps are numbered unless there is only one step.

Throughout this manual, any replaceable component, assembly, or part of the
arbitrary/function generator 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 arbitrary/function generator is a module.

Symbols and terms related to safety appear in the Safety Summary near the
beginning of this manual.

xii AFG3000 Series Arbitrary/Function Generators Service Manual

Introduction

This manual contains information that is needed to properly service the AFG3000
Series Arbitrary/Function Generators as well as general information that is critical
to safe and effective servicing.

To prevent personal injury or damage to the arbitrary/function generator, consider
the following before attempting service:

 The procedures in this manual should be performed only by a qualified service

person.

 Read the General Safety Summary on page vii and the Service Safety Summary,

beginning on page ix.

 Read Installation in Operating Basics on page 2-2.

When using this manual for servicing, be sure to follow all warnings, cautions, and
notes.

Performance Verification Procedures

Strategy for Servicing

The performance check described in the Performance Verification section should
be done every 12 months. In addition, a performance check is recommended after
module replacement.

If the AFG3000 Series 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 arbitrary/function generator.

This manual contains the information needed for periodic maintenance of the
arbitrary/function generator. Further, it contains information for corrective
maintenance down to the module level. To isolate a failure to a module, use the
troubleshooting procedures found in the Maintenance section. To remove and
replace any failed module, follow the instructions in the Removal and Installation
Procedures subsection. After isolating a faulty module, replace it with a
fully-tested module obtained from the factory. The Replaceable Parts List section
contains part number and ordering information for all replaceable modules.
