The only gain control on the DBS_RX is entirely under software control.
If the software doesn't control it, it stays the
same. I'm not sure why you're seeing magnitudes "inverted" between
DBS_RX.
Could you perhaps share the code?
I have an application that uses two DBS_RX, looking at two different
polarizations. They don't see this
phenomenon at all.
