Does any body know how to implement a Stop Trigger in Labview.

[santosh]

i am trying to implement a stop trigger based data acquisition. the aim being that the vi must start acquiring data as soon it is executed but when the trigger is applied it should store the pretrigger scans(say 100) and start acquiring the post triggered scans(say 200), display the data and then stop.
the vi must strictly be stop trigger based and not start trigger based.

LabVIEW ships with examples on how to use a trigger with a DAQ board.

You can find the examples by doing a search for examples -> I/O Interfaces -> Data Acquisition -> Analog Input -> Triggering an Acquisition.

The only difference between start and stop trigger in the VI is the pretrigger setting.
If you set the pretrigger scans greater than 2 the trigger becomes a stop trigger.
