Hey all,

I am not sure of the maximum and minimum receiver gain of XCVR2450. When
i use self.subdev.gain_range()[1]&[0] it gives 92 and 0. Are these gains
magnitudes?


Thanks in advance!

Those are intended to be roughly 1 dB steps.

No, it means that the maximum gain is approximately 92dB more than the
minimum gain.  These are relative numbers

The minimum gain setting may actually have a net loss.
