Document Number: 3700S-901-01 Rev. A / August 2007
The length of time that the trigger line will be asserted for output triggers. N is a digital
I/O trigger line: 1 to 14
To read pulse width:
width = digio.trigger[N].pulsewidth
To write pulse width:
digio.trigger[N].pulsewidth = width
pulsewidth: length in s (seconds).
N: Digital I/O trigger line: 1 to 14

The trigger line is guaranteed to be asserted for at least the specified time, and it
might be asserted slightly longer.

Setting pulsewidth to 0 (seconds) asserts the trigger indefinitely.

The default pulsewidth time is 10µs for digio lines 1 through 9, and 20µs for digio
lines 10 through 14
See digio.trigger[N].release.
Sets pulsewidth for trigger line 4 to 20µs:
digio.trigger[4].pulsewidth = 20e-6
Releases an indefinite length or latched trigger.
digio.trigger[N].release()
N: Digital I/O trigger line: 1 to 14
Releases a trigger that was asserted with an indefinite pulsewidth, as well as a trigger
that was asserted in response to receiving a synchronous mode trigger. Only the
specified trigger line (N) is affected.
digio.trigger[N].pulsewidth
Releases trigger line 4:
digio.trigger[4].release()
Event to cause this trigger to assert.
triggerstimulus = digio.trigger[N].stimulus
- or -
digio.trigger[line].stimulus = triggerstimulus
N: Digital I/O trigger line: 1 to 14
triggerstimulus: The event identifier for the triggering event.
