To test the CAL OUTPUT ports (oscilloscope)
Testing the CAL OUTPUT ports does not check a specification, but does check 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 instrument operational accuracy
calibration and probe calibration.
