This attribute selects which event(s) will cause digital output line to assert a trigger. Set
this attribute to 0 to bypass waiting for an event.
eventid may be one of the following (existing trigger event ID's):

digio.trigger[N].EVENT_ID: An edge (either rising, falling, or either based on the
configuration of the line) on the digital input line.

display.trigger.EVENT_ID: The trigger key on the front panel is pressed.

trigger.EVENT_ID: A *trg message on the active command interface. If GPIB is
the active command interface, a GET message will also generate this event.

trigger.blender[N].EVENT_ID: A combination of events has occurred.

trigger.timer[N].EVENT_ID: A delay expired.

tsplink.trigger[N].EVENT_ID: An edge (either rising, falling, or either based on the
configuration of the line) on the tsplink trigger line.

lan.trigger[N].EVENT_ID

scan.trigger.EVENT_SCAN_READY: Scan Ready Event.

scan.trigger.EVENT_SCAN_START: Scan Start Event

scan.trigger.EVENT_CHANNEL_READY: Channel Ready Event

scan.trigger.EVENT_MEASURE_COMP: Measure Complete Event

scan.trigger.EVENT_SEQUENCE_COMP: Sequence Complete Event

scan.trigger.EVENT_SCAN_COMP: Scan Complete Event

scan.trigger.EVENT_IDLE: Idle Event
To set the trigger stimulus of digital I/O line 3 to be the channel ready event during a
scan:
digio.trigger[3].stimulus = scan.EVENT_CHANNEL_READY
To clear the trigger stimulus of digital I/O line 3:
digio.trigger[3].stimulus = 0
Waits for a trigger.
triggered = digio.trigger[N].wait(timeout)
N: Digital I/O trigger line: 1 to 14
timeout: Set timeout in seconds.
triggered: Returns `true' if a trigger was detected, or `false' if no triggers were
detected during the timeout period.
This function will wait up to timeout seconds for an input trigger. If one or more trigger
events were detected since the last time digio.trigger[N].wait (this function) or
digio.trigger[N].clear (on page 9-49) was called, this function will return immediately.
After waiting for a trigger with this function, the event detector will be automatically
reset and re-armed. This is true regardless of the number of events detected.
