Trigger Modes
The DAQ-/DAQe-2213/2214 card provides four trigger sources
(internal software trigger, external analog trigger, and digital trig-
ger sources). You must select one of them as the source of the
trigger event. A trigger event occurs when the specified condition
is detected on the selected trigger source. For example, a rising
edge on the external digital trigger input. Refer to section 4.6 for
more information on SSI signals.
There are four trigger modes (pre-trigger, post-trigger, middle-trig-
ger, and delay-trigger) working with the three trigger sources to ini-
tiate different scan data acquisition timing when a trigger event
occurs. They are described in the following sections. For informa-
tion on trigger sources, refer to section 4.5.
