Hello,
I may be having similar problems. I'm using 2 basic RX boards and I want to
receive four complex signals. I seem to be losing the complex part of the
first signal. I was using a mux of 0xf3f2f1f0, and after seeing your
message, I tried 0x32103210. Both of them show the same problem with the
first signal.
I have tried swapping the usrp parts to see if it was a hardware problem,
but the problem persists.
Thanks for your help,
Hans

What are the proper mux settings for one DBSRX in RXA and one DBSRX
in RXB? When I used a single DBSRX in RXA 0x00000010 worked well.
But now I want Channel 0 to be RXA, and Channel 1 to be RXB both of
which are I and Q, and not swapped.
So far anything other than 0x32103210 or 0x00000010 produces dirty
output with random-looking noise in the data.

If you're using a single channel, usrp.determine_rx_mux_value will get you
the right answer, regardless of the type of daughterboard.
On the DBSRX, 0x00003210 (or for that matter 0x32103210) will set you
up with side A routed to channel 0 and side B routed to channel 1.
