8-6 Triggering
Trigger-In source — The Trigger-In control sources, which control individual
sweep steps, are explained as follow:

Device action
The device action block of the trigger model is where a sweep step is performed

IMMEDIATE (TRIGger:SOURce IMMediate) — Event detection for the trig-
ger layer is satisfied immediately allowing operation to continue to perform
a sweep step.
TRIGGER LINK (TRIGger:SOURce TLINk) — Event detection for the trig-
ger layer is satisfied when an input trigger via the TRIGGER LINK connec-
tor is received by the Model 622x. Note that if the source bypass is set to
ONCE (TRIGger:DIRection SOURce), operation will loop around the
source detector on the initial pass through the arm layer. Detection for each
subsequent pass is satisfied by an input trigger. The bypass resets when
the Model 622x leaves the trigger layer.
TRIGger:SIGNal (remote only) — Used as a one-time bypass for the
TRIGGER layer control source and move on to the next layer in the trigger
model (the device action in this case).
