XO compensation #2

Open Manawyrm opened 6 years ago

Manawyrm commented 6 years ago

It seems that the ad9361-phy,xo_correction attribute isn't used to correctly tune the RX LO, the frequency always seems to be out by a couple hundred Hz...

Might also be only a badly configured XO correction value on my PlutoSDR, but I don't have a stable reference clock source at hand ):

The ad9361-phy,xo_correction context attribute is purely there for information purposes.

It corrects on the Pluto itself - there isn't anything needed by the host application. It's likely that it might be a temp thing - it does take a bit for the temperature to become stable. (and the oscillator drifts about 10ppm due to temp)..
