Verifying Oscilloscope Performance - HP 54616B User And Service Manual

Verifying Oscilloscope Performance

This section shows you how to verify the electrical performance of the
oscilloscope, using the performance characteristics in chapter 5 as the
standard. The characteristics checked are calibrator, voltage
measurement accuracy, bandwidth, horizontal accuracy, and trigger
sensitivity.
You should verify the performance of the oscilloscope when you first
receive it, and every 12 months or after 2,000 hours of operation.
Also, make sure you allow the oscilloscope to operate for at least 30
minutes before you begin the following procedures.
Perform self-calibration first
For the oscilloscope to meet all of the verifications tests in the ambient
temperature where it will be used, the self-calibration tests described on page
4-25 should first be performed. Allow the unit to operate for at least 30 minutes
before performing the self-calibration.
Each procedure lists the recommended equipment for the test. You
can use any equipment that meets the critical specifications.
However, the procedures are based on the recommended model or
part number.
On page 4-19 of this chapter is a test record for recording the test
results of each procedure. Use the test results to gauge the
performance of the oscilloscope over time.
