Data streaming

Post by fraser » Fri Mar 19, 2021 10:37 am

Hi

I used Red Pitaya 125-10 to do a data streaming of voltage from a waveform generator, however, the result I got (Min, Max) is different from what I saw in the oscilloscope function.
I used the 1.04-8_beta OS, resolution is 16bit, mode is RAW and the file is saved in tdms and then transformed into csv by DIAdem.

Here are some examples I got:
Port1
Oscilloscope max 11.84V
min 57.5mv
data streaming max 9.3568V
min 36mv

Port2
Oscilloscope max 11.9V
min 58.3mv
data streaming max 9.2631V
min 29.3mv

Anyone could help me with it?

Thank you very much

If you update manually to the latest beta you will have the option to include or not the calibration data voltage offset in the streaming.
