Triggering
Triggering allows you to source signals and capture measurements when an input signal or
combination of input signals meets a set of conditions that you set. Triggering controls the timing of
when source and measure operations happen during a sweep. See
for details on sweeping.
Remote triggering overview
There are two programming methods for triggering:
•
Using the trigger model
•
Interactive triggering
You can obtain very precise timing and synchronization between channels of multiple instruments
using the trigger model to control the actions of the source-measure unit (SMU). To achieve such
precise timing, use a static trigger configuration. When a static trigger configuration is not possible,
you can use the interactive triggering method to control the timing and actions of the SMU.
Both programming methods use trigger objects. Trigger objects generate and monitor trigger events.
External triggers are possible using digital I/O, TSP-Link
the manual trigger (the TRIG key).
The following figure graphically represents all the trigger objects of the Model 2651A instrument.
