NI DAQ 6361 Generate voltage upon trigger and stop generation upon stop trigger

[caca1409]

I have been working to generate a voltage upon trigger, where upon the voltage detected on the analog input reaches 2.0V, a voltage will be generated in the output. However, when the voltage detected on the analog input is below 2.0V, no voltage will be generated in the output.

I have been thinking about using DAQmxCfgDigEdgeStartTrig() function to start the trigger, but how do i stop the trigger?  So far what I have found out are reference triggers to stop voltage acquisition.

Is there any way to stop voltage generated at the stop signal?

I would like to clarify that once the trigger condition(the falling edge) is met, the voltage output will stop.

How do I do that?

I'm not totally clear what you mean by "voltage output will stop" does that mean output 0 Volts or are you trying to tristate the output?

Would something like this work:

If you are looking for a hardware based solution maybe the folk over at Multifunction DAQ could help out.

My inclination is to checkout the "analog triggering" section in this article:

to generate a trigger for your analog output.
