Introduction
Service Strategy
STOP. Throughout this manual, any field-replaceable component, assembly, or
part of this oscilloscope is referred to generically as a module.
This manual contains all the information needed for periodic maintenance of the
TDS 684A and 7XXA Digitizing Oscilloscopes. (Examples of such information
are procedures for checking performance and for readjustment.) Further, it
contains all information for corrective maintenance down to the module level.
This means that the procedures, diagrams, and other troubleshooting aids help
isolate failures to a specific module, rather than to components of that module.
Once a failure is isolated, replace the module with a fresh unit obtained from the
factory.
All modules are listed in Mechanical Parts List. To isolate a failure to a module,
use the fault isolation procedures found in Section 6, Maintenance Information.
To remove and replace any failed module, follow the instructions in Removal
and Installation Procedures
, also found in Section 6.
