Philip,
I'm acquiring data at 44KHz sample rate and my frequency range is 0-20kHz (2 ni-4472 DAQ cards). Since I been using LV (off and on now for about a year) my application is still in the development stage. I tried including pics but could only include 1 at a time, so heres a copy of my vi for you. There is several things I'd like to figure out, I'm viewing data real-time and writing data to file. However, as I'm writing data to file I don't want the data to display in real-time (I think this is where my problem is). The other issued is when I've stopped writing data to file, the case structure outside the while loop opens the file and processed the data, however I'd like to see the data in the same display (waveform graph in while loop). Take look and give me thoughts.
