I am using Labview Express 7.0 and I have am trying to acquire data for 64 channels from NI's PCI607E card.
I sample at about 20 Khz and collect about 2000 samples. Currently I am using reference anlog trigger. It works fine right now. But I would like to chenge the triggering to a software type. I am trying to add up the amplitudes of my 64 channles of signals (amplitude wise) and taking that summed signal to trigger the DAQ card to commence writing the data into a data file. How can I get this going?
