Hello.
I have a two part question regarding a voltage measurement I'm trying to build. I have no prior DAQmx experience so the first question is simple:
How should I build multiple measurements to execute at the same time? I tried building parallel measurement branches in to the example in the attachment but apparently I cant run two tasks at the same time? I would like to get multiple measurement from multiple DAQ modules.
Second question is: can I (or should I) vary sampling rates virtually with for example a for loop? I would need to record voltages logarithmically so that I have fast sampling speeds in the beginning and it slows down. Is there a better way of doing this? When Im done with the program (and after upgrading my module) I should have measurements at 1 MS/s in the beginning and 1 S/s in the end. In between around 30-50k samples.
At the moment I have NI 9205 modules for testing but Im planning on upgrading to NI 9223 later for faster sampling speeds.
