Trigger events are identified by means of an event ID. The following table describes the trigger event
IDs.
Trigger event IDs*
Event ID**
Event description
smu X .trigger.SWEEPING_EVENT_ID
Occurs when the source-measure unit (SMU)
transitions from the idle state to the arm layer of the
trigger model
smu X .trigger.ARMED_EVENT_ID Occurs when the SMU moves from the arm layer to
the trigger layer of the trigger model
smu X .trigger.SOURCE_COMPLETE_EVENT_ID Occurs when the SMU completes a source action
smu X .trigger.MEASURE_COMPLETE_EVENT_ID Occurs when the SMU completes a measure action
smu X .trigger.PULSE_COMPLETE_EVENT_ID Occurs when the SMU completes a pulse
smu X .trigger.SWEEP_COMPLETE_EVENT_ID Occurs when the SMU completes a sweep
smu X .trigger.IDLE_EVENT_ID Occurs when the SMU returns to the idle state
digio.trigger[ N ].EVENT_ID
Occurs when an edge is detected on a digital I/O line
tsplink.trigger[ N ].EVENT_ID Occurs when an edge is detected on a TSP-Link line
lan.trigger[ N ].EVENT_ID Occurs when the appropriate LXI trigger packet is
received on LAN trigger object
N
display.trigger.EVENT_ID Occurs when the TRIG key on the front panel is
pressed
trigger.EVENT_ID
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).
**
smu X
: For Models 2601B, 2611B, and 2635B, this value is
smua
(SMU Channel A); for Models 2602B, 2604B,
2612B, 2614B, 2634B, and 2636B, this value can be
smua
(for SMU Channel A) or
smub
(for SMU Channel B).
Using the remote trigger model
The source-measure unit (SMU) in the Series 2600B 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.
