Fail: This parameter shows the number of times the oscilloscope has triggered and the
trace has gone outside of the mask area.

the failed waveform outside the masked area will be red.
Off: The oscilloscope will continue with the test even though failed waveforms are
detected. The test results on the screen will update continuously and a pulse will be
output from the PASS/FAIL BNC connector (if enabled) on the rear panel each time a
failed waveform is detected.
