Immediate Triggering (TRIG:SOUR IMM)
TRIG:SOUR IMM sets immediate (internal) triggering. The scan list is automatically advanced. This is the default trigger mode.
External Trigger (TRIG)
TRIG:SOUR EXT sets external triggering. The trigger source is a (user supplied) input to the Event In port. Use a +5V
With two or more switchboxes in a mainframe, the first switchbox set for EXT trigger keeps the trigger resource until the switchbox source is changed to BUS, HOLD, or IMM.

Bus Triggering (TRIG:SOUR BUS)
TRIG:SOUR BUS defines trigger source as a *TRG or GET command executed over the
Enabling Trig Out Port (OUTP ON)
The Trig Out port is shared by all instruments in the mainframe. With the port enabled (with OUTP ON), it generates an output trigger after each channel closure for ANY switchbox in the mainframe. The Trig Out port outputs a +5V
