Calibrating and Adjusting
This section gives you instructions for calibrating and adjusting the
oscilloscope. Adjustments to the oscilloscope include adjusting the
CRT monitor assembly.
To periodically verify the performance of the analyzer, refer to the optional
Service Guide.
Calibration frequency
The oscilloscope circuitry in the HP 16533/34A oscilloscope requires an
operational accuracy calibration by the user or service department under
any of the following conditions:
•
at six months intervals or every 1,000 hours
•
if the ambient temperature changes more than 10° C from the
temperature at full calibration
•
to optimize measurement accuracy
To test the oscilloscope circuitry against specifications, refer to "Testing
Performance" in chapter 3 of the Service Guide.
Multi-card oscilloscope calibration
A complete operational accuracy calibration on an HP 16533/34A multi-card
module requires the module to first be separated into single-card modules.
The operational accuracy calibrations on the acquisition subsystem are done
on the single-card modules. After reconfiguring the HP 16533/34A module
into a multi-card module, the timebase operational accuracy calibrations are
done.
