8.8 Trigger Output Connector
The rear-panel trigger output connector ([AUX OUT]) of this series can output trigger
signals determined by the current setting (hardware trigger).
Click or tap > Utility. Click or tap Setup, and then select "TrigOut" in Aux Out. A
signal which reflects the current oscilloscope capture rate can be output from [AUX
OUT] connector each time a trigger is generated by the oscilloscope. If this signal is
connected to a waveform display device to measure the frequency, the measurement
result is the same as the current capture rate.
If "PassFail" is selected in Aux Out, the instrument can output a pulse from the [AUX
OUT] connector when a pass/failed event is detected during the pass/fail test.
