Hi, Within the last couple of weeks, the N310 tree went from having 1 front end to 2 front ends per daughterboard (A,B,C, or D). What is the reason for this? Why would the user want to choose subdev spec "A0" as opposed to "A1" and same for other paths? I attached the uhd_usrp_probe results

Dear community, I implemented C++ codes of the transmitter and receiver using UHD API, starting from example provided by Ettus. Until now, I'm testing my codes using a coax cable for connecting the USRPs (a USRP used as transmitter and a USRP used as receiver). In this setup, just before
