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:
H Names of front panel controls and menus appear in the same case (initial
capitals, all uppercase, and so forth) in the manual as is used on the RTX100A front panel and menus.
H Instruction steps are numbered unless there is only one step.
H Bold text refers to specific interface elements that you are instructed to
select, click, or clear .
Example: To power on the RTX100A, press the ON/STBY switch.
H Italic text refers 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 RTX100A 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 RTX100A 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 RTX100A includes:
H The RTX100A ISDB-T RF Signal Generator User Manual (Tektronix part
Example: The Diagrams section, beginning on page 7-1, includes a block diagram and an interconnect diagram.
number 071-1755-XX) contains a tutorial to quickly describe how to operate the RTX100A. It also includes an in-depth discussion on how to use the RTX100A features.

Introduction

This manual contains information needed to properly s ervice the RTX100A ISDB-T RF Signal Generator, as well as general information critical to safe and effective servicing.
To prevent personal injury or damage to the RTX100A, 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 vii.
When using this manual for servicing, be sure to follow all warnings, cautions, and notes.

Performance Check Interval

Generally, the performance check described in Section 3, Performance Verifica­tion, should be done every 12 months. In addition, a performance check is
recommended after module replacement.

Strategy for Servicing

If the RTX100A does not meet performance criteria, repair is necessary.
This manual contains all the information needed for periodic maintenance of the RTX100A.
This manual also 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 5, Maintenance. To remove and replace any failed module, follow the instructions in Removal and Installation Procedures, also part of Section 5. After isolating a faulty module, replace it with a fully-tested module obtained from the factory. Section 8, Replaceable Parts List, contains part number and ordering information for all replaceable modules.
