Edge Triggered Trigger Acquisition
The Edge Triggered mode is enabled by setting TriggerAcquisition_Mode to Edge and
TriggerAcquisition_Enable=True. Two signals act as trigger enable (see Fig. 5.29). A rising edge
on the start signal enables triggering. A rising edge on the stop signal disables all triggers. The
start/stop signals are selected by TriggerAcquisition_StartSource and
TriggerAcquisition_StopSource.

Trigger Acquisition and Free-Running Trigger
The TriggerAcquisition feature can also be used with free-running trigger (TriggerMode=Off).
TriggerAcquisition enables or disables in this case the generation of the free-running trigger.
5.4.12 Strobe Output
The strobe output is an isolated output located on the power supply connector that can be
used to trigger a strobe. The strobe output can be used both in free-running and in trigger
mode. There is a programmable delay available to adjust the strobe pulse to your application.
The strobe output needs a separate power supply. Please see Section 6.8, Fig.
5.16 and Fig. 5.17 for more information.
