SoapySDRUtil --probe="driver=lime" to get the names of the ports. In this case, the names are based off of the LMS7, not the silkscreen, These are the options
- Rx Antennas: LNAH, LNAL, LNAW, LB1, LB2
- Tx Antennas: BAND1, BAND2
You will see the two tx antenna options for each channel and the 3 rx options for each channel. The loopbacks are just internal to the LMS7. Mostly for debug, but they are there too as a useful options.
