Hello,
I using a usrp1 populated with 2 LF-RX and 2 LF-TX.
I want to use 2 DDCs the I-inputs of which are connected to the 2 ADCs
on LF_RX A (Q-inputs to gnd).
In pre-uhd times I used to use set_mux, but now the API seems to have
changed.
The following code produces the error message:
AttributeError: ‘uhd_usrp_source_sptr’ object has no attribute ‘set_mux’
How can I control the mux in the RX-path of the usrp1?
