I ’am using a Picoscope 4262 with Labview 2012 SP1 on a Win7 32-bit system. I want to use the PS4000_stream VI, to measure two channels and write the collected data in a text-file. But the saved samples had some constantly recurring gaps or dropped samples. I modified the frame which is keeping the array length equal to “number of samples”.
Now I get a continuous Measurement. The current problem is a varying number of samples for one period of the measured signal. The number varies between approximately 1945 and 1960 samples for one period of a 50 Hz signal. I ’am searching for a way to collect and save a constant number of samples for a specific time range, e.g. 2000 samples for 20 ms.
I would be very gratefull if you could help me,
