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 t hat
they can provide accurate calibration for the instrument operational accuracy
calibration and probe calibration.
