Model 2601B-PULSE System SourceMeter Instrument Reference Manual Section 6: Triggering

Occurs when a *TRG command is received on the
remote interface
GPIB only: Occurs when a GET bus command is
received
USB only: Occurs when a USBTMC TRIGGER
message is received
VXI-11 only: Occurs with the VXI-11 command
device_trigger; reference the VXI-11 standard for
additional details on the device trigger operation
trigger.blender[N].EVENT_ID
Occurs after a collection of events is detected
trigger.timer[N].EVENT_ID
Occurs when a delay expires
trigger.generator[N].EVENT_ID
Occurs when the
trigger.generator[N].assert() function is
executed
* Use the name of the trigger event ID to set a stimulus value rather than the numeric value. Using the name
makes the code compatible for future upgrades (for example, if the numeric values must change when
enhancements are added to the instrument).
Using the trigger model
The source-measure unit (SMU) in the 2601B-PULSE has a remote trigger model that supports a
wide range of triggering features for source sweeps, triggered measurements, and pulse actions.
Measurements using the trigger model can be made synchronously with sourcing actions or they can
be made asynchronously. The following figures graphically illustrate both modes of the remote
trigger model.
When the smua.trigger.measure.action attribute is set to smua.DISABLE or smua.ENABLE,
the trigger model operates in synchronous measurement mode. When it is set to smua.ASYNC, it
operates in asynchronous mode.
