Question: how to receive from Rx-A and Rx-B of a single daughterboard

I have a problem. I newly purchased a Basic Rx
daughterboard and I tried using the usrp_oscope.py
file to test whether or not my daughterboard works.

Unfortunately, only the Rx-A portion seems to be
working. Is this always the case? Is there something
that I should do so that I could receive from the Rx-B
portion. I mean, it’s really weird that I have two
input ports (since there are two SMA connectors that
serve as input to the Basic Rx Daughterboard), but I
can only pass input to one of them.

Is the RX-B just a decoration? Could I use both ports
simultaneously?

I will greatly appreciate your replies. Thanks!

$ foo.py -R a:1

Yes.

Try

$ usrp_oscope.py --help
