Aux Output
Users can set the type of the signal output from the [Trigger Out] connector on the
rear panel.
Press Utility  AuxOutput to select the desired output type.
 TrigOut
After this type is selected, the oscilloscope outputs a signal that can reflect the
current capture rate of the oscilloscope at each trigger. Connect this signal to a
waveform display device, measure the signal frequency and the measurement
result equals the current acquisition rate.
 PassFail
After this type is selected, the oscilloscope will output a pulse signal from the
[Trigger Out] connector on the rear panel when failed waveforms are detected
in the pass/fail test.
