To test the CAL OUTPUT ports
This test does not need to be performed every time an operational accuracy
calibration is done. Testing the oscilloscope CAL OUTPUT ports checks the following:
•
DC CAL OUTPUT voltage
•
AC CAL OUTPUT voltage
This test verifies that the CAL OUTPUT voltages are operating within limits, so that
they can provide accurate calibration for the oscilloscope operational accuracy
calibration and probe calibration.
