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
RTX100B 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: Press the Menu button to open the File menu.
H Italic text refers to document names or sections. Italics are also used in
NOTES, CAUTIONS, and WA RNINGS.
Modules
Safety
Throughout this manual, any replaceable component, assembly, or part of the
RTX100B 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 RTX100B 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 RTX100B includes:
H The RTX100B 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 071-1930-XX) contains a tutorial to quickly describe how to operate
the RTX100B. It also includes an in-depth discussion on how to use the
RTX100B features.

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 RTX100B does not meet performance criteria, repair is necessary.
This manual contains all the information needed for periodic maintenance of the
RTX100B.
This manual also contains all information for corrective maintenance down to the
module level. To isolate a failure to a module, use t he 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.
