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?


Those are intended to be roughly 1 dB steps.

Hi Matt,

Sorry.But i did not get it.
you mean, its maximum gain is 92dB?


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.
