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

Event blender modes
Event blenders can be used to perform logical AND and logical OR functions on trigger events. For
example, trigger events can be triggered when either a manual trigger or external input trigger is
detected.
• Or: Generates an event when an event is detected on any one of the four stimulus inputs
• And: Generates an event when an event is detected on all of the assigned stimulus inputs
Set the trigger.blender[N].orenable attribute to configure the event blender mode. Setting
the attribute to true enables OR mode; setting the attribute to false enables AND mode.
Assigning input trigger events
Each event blender has four stimulus inputs. A different trigger event ID can be assigned to each
stimulus input. The programming example below illustrates how to assign the source complete event
to stimulus inputs 1 and 2 of event blender 1:
trigger.blender[1].stimulus[1] = smua.SOURCE_COMPLETE_EVENT_ID
Action overruns
Action overruns are generated by event blenders depending on the mode, as shown in the following
table. Use the status model to monitor for the occurrence of action overruns. For details, see the
Status model (on page 15-1).
Generates an overrun when a second event on any of its inputs is detected
before generating an output event.
Generates an overrun when two events are detected simultaneously.
LAN triggering overview
Triggers can be sent and received over the LAN interface. The 2601B-PULSE supports LAN
extensions for instrumentation (LXI) and has eight LAN triggers that generate and respond to LXI
trigger packets.
