Pluto rx adc different reference level problem

Hello

I measured today twice using pluto rx function in python.

Once the transmitter was active before the beginning of rx and the second time it only started after receiving.

On both times the noise level was different. It was like the pluto adjust by itself the adc reference level According to the first sample.

On both time the hardware gain was manually controlled and the same.

Do you know why it happens?

Thanks,

Etamar

    1. If i calibrate the devie once, and afterwards save all the gain table used, only to charge them in later use - will it the measurement results be repeatable? 

    I cannot guarantee this. You will…
