I am trying to use 3 picoscope 5442B with Labview to collect 12 channels of data at the same time. I am using streaming mode. At first, I can run the single-picoscope in my program very well. However, When I copied another call function in the labview, I get all 0 values from the second picoscope, while the first one works fine. It is not a hardware problem. The single-picoscope labview program works fine on each picos separately. Can anyone look into my code and see anything wrong? Thank you very much.
