I am new to programming in Labview and I need to write a software to automatically run the Picoscope and acquire data. I am basically scanning an object with a probe and recording the amplitude of the signal at a given frequency (plus harmonics). I have used the example programs given by Picoscope and made an attempt at writing the Labview program so that it does the above, using the Fast streaming functions. I basically open the Picoscope, set the channels, and then I loop over each position of the probe. At each iteration I ask the user whether the probe has been repositioned and once I have confirmation (by clicking 'OK' on a pop up message) I use StartPolling and then FastStreaming. I sample 8192 samples and perform an FFT and store the values. My problem is that if I wait a few minutes before clicking on 'OK' the sampling becomes chaotic. Do you know why?
Many thanks and apologies for the long explanation
