Adjustment Procedures
This section contains information about instrument adjustment. Only quali fi ed
personnel should perform adjustment procedures. Read the Service Safety
Summary and the General Safety Summary before performing any service
procedures.
NOTE.
Before performing adjustment procedures, you must warm up the arbitrary
waveform generator at least 20 minutes in an ambient temperature between 20 °C
and 30 °C. Adjustments performed before warm-up or outside this temperature
range may result in poor performance.
Adjustment Interval
If the instrument fails performance tests (refer to the AWG7000 Series Arbitrary
Waveform Generators Technical Reference Manual ), adjustment may be required.
If periodic calibration is one of your requirements, a general rule is to verify
performance and make adjustments (if needed) every 2000 hours of operation (or
once a year if the instrument is used infrequently).
Adjustment After Repair
After removal and replacement of a module due to electrical failure, you must
perform the adjustment procedure if the module you replaced is marked “yes” in
the following table. (See Table 3-1.)
