Service Safety Summary
x AFG3000 Series Arbitrary/Function Generators Service Manual
Preface
This manual provides instructions to verify the performance of, calibrate,
troubleshoot, and repair the arbitrary/function generators to the module level.
Unless noted otherwise, the term “AFG3000 Series” refers to the models in the
AFG3021, AFG3022, AFG3101, AFG3102, AFG3251, and AFG3252
arbitrary/function generators.
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
module level.
Performance Verification contains procedures for confirming that the
arbitrary/function generator functions properly and meets warranted limits.
Adjustment Procedures contains information that you need to manually adjust
the arbitrary/function generator so that it meets specifications.
Maintenance contains information and procedures for performing preventive
and corrective maintenance of the arbitrary/function generator. These
instructions include cleaning, module removal and installation, and fault
isolation to the module.
Replaceable Electrical Parts contains a statement referring you to Replaceable
Mechanical Parts, where both electrical and mechanical modules are listed.
Diagrams contains interconnection diagrams.
Replaceable Mechanical Parts includes a table of all replaceable modules,
their descriptions, and their Tektronix part numbers.

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 the user with basic instrument features.
AFG3000 Series Reference 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.
AFG3000 Series Built-in Help A built-in help system, integrated with the User Interface application that ships with this
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 Information 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 Mechanical Parts
section contains part number and ordering information for all replaceable modules.
