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 dc 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 4–31 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.
Starting on page 4–23 is a series of test records (one for each model of
osciiloscope) for recording the test results of each procedure. Use the
test results to gauge the performance of the oscilloscope over time.
