I am trying to develop a system capable of measuring 1 kHz signals from a photodiode using a low power useless leak in my experiment in order to be able of measure energy without disturbing the results. I am having two problems with the program: the first one is that I can't measure all the data (I only measure just at 50 Hz), ie my program is slow and I don't know why, and the second one is that I can't get a good SNR. The point is that with the software PicoScope 6 I can see the pulses perfectly but not on LabView (images attached). I will apreciate any help. I am a bit desperate at this point because I have spend a lot of time trying to solve these issues without being able to do it.
Thank you very much
