LEVEL OF
MAINTENANCE
Maintenance of the 682XXB/683XXB consists of:
G
Troubleshooting the instrument to a replaceable subassembly or
RF component.
G
Repair by replacing the failed subassembly or RF component.
G
Calibration.
G
Preventive maintenance.
Troubleshoot-
ing
The 682XXB/683XXB firmware includes internal
diagnostics that self-test most of the internal assem-
blies of the instrument. When the signal generator
fails self-test, one or more error messages are dis-
played to aid in troubleshooting the failure to a
replaceable subassembly or RF component. Chapter
5 lists and describes the self-test error messages
and provides procedures for isolating 682XXB/
683XXB failures to a replaceable subassembly or RF
component.
Repair
Most instrument failures are field repairable by re-
placing the failed subassembly or RF component.
Detailed instructions for removing and replacing
failed subassemblies and components are provided
in Chapter 6.
Calibration
The signal generator may require calibration after
repair. Refer to Chapter 4 for a listing of calibration
requirements and calibration procedures.
Preventive
Maintenance
Preventive maintenance on the 682XXB/683XXB
consists of cleaning the fan honeycomb filter, de-
scribed in paragraph 1-8.
