Maintenance of the 682XXB/683XXB consists of:

MAINTENANCE

Troubleshooting the instrument to a replaceable subassembly or

 

 

RF component.

 

Repair by replacing the failed subassembly or RF component.

 

qCalibration.

 

 

Preventive maintenance.

 

Troubleshoot-

The 682XXB/683XXB firmware includes internal

 

ing

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.
