Aux Output 
 
Users can set the oscilloscope to output the specified type of signal from the [Trig 
Out/Calibration] connector at the rear panel. 
 
Press Utility  AuxOutput and turn the multi-function knob   to select the 
desired signal type. You can also press AuxOutput continuously to switch the 
current signal type.  
  TrigOut 
The oscilloscope outputs a signal that can reflect the current capture rate of the 
oscilloscope from the [Trig Out/Calibration] connector at the rear panel at 
each trigger. Connect the signal to a waveform display device and measure the 
frequency of the signal; the measurement result is the same as the current 
capture rate. 
 
  Fast 
The oscilloscope outputs a fast edge signal with 500 ps rise time from the [Trig 
Out/Calibration] connector at the rear panel. The signal can be used in the 
self-calibration of the oscilloscope (refer to “Self-calibration”). 
 
  GND 
The oscilloscope outputs a ground level from the [Trig Out/Calibration] 
connector at the rear panel. 
 
  PassFail 
The oscilloscope will output a pulse from the [Trig Out/Calibration] 
connector at the rear panel when failed waveforms are detected. This signal can 
be connected to other control systems to conveniently view the test results.  
 
Note: You can also modify the signal type of AuxOutput in the pass/fail test 
function (refer to “
To Set the Output Form of Test Failure”).
