Hello,
I am new to LabView. I am using USB-6009 to recieve signal from two channels (ai0 and ai1) and want to show and read data once the external trigger pulse (PFI0) is on the rising edge. The trigger pulse is a periodic pulse. My old program works well in the old version of LabView (See attached figure). However, in my new program (See attached file), once triggered at the first pulse, the data acquisition process is on and data are scanned since then. I want the data to be scanned every time the external trigger pulse (PFI0) is on the rising edge. It seems to be an easy question, but I cannot figure it out. Any help is appreciated. Thank you.
