I’m using a UBX-160 daughterboard. My application uses less than 50

In past experimentation I’ve done, changing the RF gain takes on the

of magnitude faster than that.
Ah, in which case, your baseband-based approach makes sense.
So unless your existing codebase is "on the edge" of being unable to
keep-up at your sample rates, then doing a complex multiply in software
would be the way to go.
It could also be done in RFNoC, but you'd have to ramp-up on RFNoC, and
unless there's a strong performance reason for doing it in RFNoC, stick
with the
software side.
