The parameters are
 Fail: This parameter shows the number of times the oscilloscope has triggered and the
trace has gone outside of the mask area.
 Pass: This parameter shows the number of times the oscilloscope has triggered and the
trace has stayed within the mask area.
 Total: This parameter shows the number of times the oscilloscope has triggered. It is the
sum of the Pass and Fail parameters.
11. Press the Next Page softkey to go to the second page of the PASS/FAIL menu.
12. Press the Stop on Fail softkey to turn on or off the function.
 On: When a failed waveform is detected, the oscilloscope will enter the STOP state. The
results of the test remain on the screen (if the display is turned on) and one pulse is
output from the PASS/FAIL BNC connector (if enabled) on the rear panel. The portions of
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.
 Note: To enable the output pulse, press Utility → Next Page → I/O → Aux Output until
the last softkey displays Pass/Fail.
