Trigger Output Connector
The trigger output connector ([Trigger Out]) on the rear panel of the oscilloscope
can output trigger signals determined by the current setting.
The oscilloscope can output a signal that reflects the current capture rate of the
oscilloscope from the [Trigger Out] connector each time a trigger is generated.
Connect the signal to a waveform display device and measure the signal frequency;
the measurement result is the same with the current capture rate.
Note: If Utility  AuxOutput is set to "PassFail" or Utility  Pass/Fail 
AuxOutput is set to "ON", during the pass/fail test, the oscilloscope will output a
negative pulse through the [Trigger Out] connector each time a failure is detected;
the oscilloscope will output low level continuously through the [Trigger Out]
connector when no failure is detected.
