Figure 10-3 graphically illustrates this example. See Section 9 for more information on sweep
operation.

Using trigger events to start actions on trigger objects
Trigger objects can be configured to respond to events generated by other trigger objects, such as
using a digital I/O trigger to initiate a sweep. To configure a trigger object to monitor for an event,
assign the event ID of the trigger event to the stimulus input. When the specified trigger event
occurs, the trigger object will perform an action.
Example:
-- Configure digio line 2 to generate an output trigger pulse each
-- time SMU A generates a source complete event.
digio.trigger[2].stimulus = smua.trigger.SOURCE_COMPLETE_EVENT_ID
Figure 10-4 illustrates this example.
The stimulus input can be configured to monitor for only one trigger event ID at a time. To monitor
more than one event, use an event blender. For example, you can configure the Series 2600A to
generate an external output trigger when sweeps on both SMU A and SMU B are complete. See
Event blenders for more information.
