i want to use ni-scope to drive pxi5105. And the PFI1 connect to a digital pulse signal(10KHz, 0-3.3V), to control a single channel analog signal continuous sample(Chan 0). I want a loop when the digital signal falling, the analog singal start to sample, and when the digtal signal rising, the analog singal stop. And by the low level of the digital singal, the analog singal sample (coupling by DC) can get an average and export to txt. I have tried the "start_and_reference_trigger.vi " and it did not work correctly. i need your help, thank you very much.
