To run the self calibration

To run the self calibration

The self calibration uses signals generated in the oscilloscope to calibrate channel sensitivity, offsets, and trigger parameters. You should run the self calibration

•yearly, or according to your periodic needs,

•when you adjust or replace the acquisition assembly or acquisition hybrids,

•when you replace the hard drive or any other assembly,

•when the delta temperature is more than ±5 °C different than the last calibration, or

•after performing incoming performance verification and before performing outgoing performance verification.

Let the Oscilloscope Warm Up Before Running the Self Calibration

The self calibration should only be done after the oscilloscope has run for one half hour at ambient temperature with the cover installed. Calibration of an oscilloscope that has not warmed up may result in performance test failure.

Calibration time

It will take approximately 45 minutes to run the self calibration on the oscilloscope, including the time required to change cables from channel to channel.
