thank’s for the hint - but this is not quite what I want to do:
In the future I want to use 4 separate inputs - this is for a
network-analyzer with 2 directional couplers for S11, S21, S12, S22.
For a start I want to use only RX-board A with 2 different signals on
both inputs. This implies that the Q-inputs of the DDCs must be
connected to 0.
I guess the subdev spec would be:
“A:A A:B” ?
What would be the setting to use all 4 input?

How can I control the mux in the RX-path of the usrp1?
Set the subdevice specification to “A:A B:A”. This maps the DDC0 to
dboard A, frontend A and DDC1 to dboard B, and frontend A.
