4.13.3 Trigger Subsystem
The Trigger Subsystem is used to control the waveform triggering. The command structure is as follows:
:TRIGger
:MODE CONTinuous|TRIGger|GATE|BURSt
:BURSt <numeric value>
:SOURce <MANual|INTernal|EXTernal|BUS
:TIMer <numeric value>
Note: For model 4079, nothing changes in the commands above to control channel 1. But for channel 2,
change :TRIG to :TRIG2. For example, to change channel 2 mode to gate, send the command:
TRIG2:MODE GATE.
