This manual is divided into sections, such as the 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 following are brief descriptions of each manual section.

 Specifications contains a description of the sync pulse 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 a sync pulse

generator functions properly and meets warranted characteristics.

Preface

Manual Conventions

This manual uses certain conventions with which you should become familiar.

Some sections of the manual contain procedures for you to perform. To keep those instructions clear and consistent, this manual uses the following conventions:

 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 sync pulse generator front panel and menu.

 Instruction steps are numbered unless there is only one step.  Bold text refers to specific interface elements that you are instructed to select,

click, or clear. Example: Press the SYSTEM button to display the System menu.

 Italic text refer to document names or sections. Italics are also used in NOTES,

CAUTIONS, and WARNINGS.

Modules

Safety

Throughout this manual, any replaceable component, assembly, or part of the sync pulse 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 sync pulse generator is a module.

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

Finding Other Information

Other documentation for the sync pulse generator includes:

 The SPG600 & SPG300 Sync Pulse Generators User Manual (Tektronix part

 The SPG600 & SPG300 Sync Pulse Generators Quick Reference Manual

Example: Section 10, Mechanical Parts List, lists all field replaceable modules by part number.

number 071-1340-XX) contains a tutorial to quickly describe how to operate the sync pulse generator. It also includes an in-depth discussion on how to more completely use the sync pulse generator features.

(Tektronix part number 071-1341-XX) contains information to enable you to quickly get an overview of front-panel buttons, rear-panel connectors, and menus.

xiv SPG600 & SPG300 Sync Pulse Generators Service Manual

Introduction

This manual contains information needed to properly service the SPG600 and SPG300 Sync Pulse Generators, as well as general information critical to safe and effective servicing.

To prevent personal injury or damage to the sync pulse 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 and the Service Safety Summary , beginning

on page ix.

 Read Installation 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, a performance check is

recommended after module replacement.

If the sync pulse generator 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 sync pulse generator.

This manual contains all the information needed for periodic maintenance of the sync pulse generator (examples of such information are procedures for checking performance).

Further, this manual contains all information for corrective maintenance down to the module level. T o isolate a failure to a module, use the fault isolation procedures found in Troubleshooting, part of section 6, Maintenance. To remove and replace any field module, follow the instructions in Removal and Installation Procedures, 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.
