Triggered data acquisition on 3 channels with pretriggering

I'm trying to perform a data acquisition using a daqpad 6052. I have 3 chanels 0,1 and 2. I'd like to trig on chanel 0. And have a pretrig of 5000 pts.

LV tells me that "NI-DAQ LV: The specified trigger signal cannot be assigned to the trigger resource."

Thanks for your help

Hi,

Try an example that ships with LabVIEW. Note that not all sources can be set as a trigger. Also, make sure that channel 0 is the first channel in the channels list.

I'm using the exemple "Acquire N Scans Analog Hardware Trig.vi" from NI to test this. I specified chanel 0 and 1 and trigger on chanel 0. If the pretrig param is lefet to 0 is works fine but if a set it to 50 it gives me a configuration problem. I have included the vi with the parameters saved in the interface. Check this out.

Thanks. You can contact me directly if needed at landry.champlain@ireq.ca
