To Run The Self Calibration - Keysight 9000 Series Service Manual

To run the self calibration

Let the Oscilloscope Warm Up Before Adjusting
Warm up the oscilloscope for 30 minutes before starting calibration procedure. Failure to allow
warm up may result in inaccurate 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 replace the acquisition assembly or acquisition hybrids,
• when you replace the hard drive or any other assembly,
• when the oscilloscope's operating temperature (after the 30-minute warm-up period) is more than
±5 °C different from that of the last calibration.

Calibration time
It will take approximately 1 hour to run the self calibration on the oscilloscope, including the time
required to change cables from channel to channel.
1 Let the oscilloscope warm up before running the self calibration.
The self calibration should only be done after the oscilloscope has run for 30 minutes at ambient
temperature with the cover installed. Calibration of an oscilloscope that has not warmed up may result
in an inaccurate calibration.
Pull down the Utilities menu and select Calibration.
