performance check is recommended after module replacement.
If the waveform generator does not meet performance criteria, repair is
necessary.
Strategy for Servicing
Throughout this manual, the term, module, refers to any field-replaceable
component, assembly, or part of the waveform generator.
This manual contains all the information needed for periodic maintenance of the
waveform generator. Further, it contains all information for corrective mainte-
nance down to the module level. To isolate a failure to a module, use the
troubleshooting procedures found in section 6, Maintenance. To remove and
replace any failed 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.
