Data streaming, non aggregated

Hi!

I have a problem with data streaming with the 5203. I use the sample code from the webside and try to change it to my topics. I don't need the aggregated data sampling and want to use the non-aggregated (I need the maximum sampling frequency).
I changed the ps5000RunStreaming to downSampleRatio=1. Now the program runs in an endless loop without collecting more data after the first block.
(I use the ps5000SetDataBuffer-Funktion)

Any ideas whats wrong?

Greetings

Frank

Hi,

Try setting the overview buffer to a larger size. Ie. 1000000, it could be that this buffer is filling up to fast.

When collecting data in streaming and setting the downSampleRatio to 1 and collecting at it maximum capacity then the PC may not be able to keep up with the data rate from the device and lost samples will be occur.
