How to control several input channels analog daqmx for data acquisition trigger (all on the same SMU-6368)

Using the SMU-6368 module, I would like to monitor the analog signal on multiple channels and trigger on several channels - relaxation and acquisition channels is all on the same device. Probably going to be sampling at 200 kHz and more. FM LV 2009 2012, with SV toolkit in Windows 7.

If SW trigger is the only way to follow, there example code shows how to manage the block size, etc.. ?

jkessler,

Yes, the example was in 2012.  I didn't get what you asked for in your first post because I didn't know you wanted to ANY channel to trigger acquisition of all channels.  It is not possible at the hardware level, because you cannot specify four channels as the command source. This will be implemented in the software.  I recommend the reading of all four channels and neglecting data until you determine that one of the channels reached your threshold value.

Kind regards
