Output characteristics
:
•
In addition to trigger events from other trigger objects, the
digio.trigger[
N
].assert()
and
tsplink.trigger[
N
].assert()
functions generate a low pulse for the programmed pulse
duration if the line is latched low, a falling edge does not occur.
•
A normal falling edge pulse generates when the internal drive is not latched low and the
digio.trigger[
N
].assert()
and
tsplink.trigger[
N
].assert()
functions are issued.
•
To mirror the SynchronousA trigger mode, set the pulse width to 1
μ
s or any small nonzero value.
•
Action overruns are disabled.
