Section 10: Triggering
Remote triggering overview
There are two programming methods for triggering:
•
Using the trigger model.
•
Interactive triggering.
Using the trigger model to control the actions of the SMU allows the user to obtain very precise
timing and synchronization between SMUs of a single instrument or between channels of multiple
instruments. To achieve such precise timing, a static trigger configuration must be used. When a
static trigger configuration is not possible, the interactive triggering method can be used to control
the timing and actions of the SMU.
Both programming methods use trigger objects. Trigger objects generate and monitor for trigger
events. External triggers are possible using digital I/O, TSP-Link synchronization lines, LAN,
command interface, and the manual trigger (the
TRIG
key).
