[srsran-users] Using Both RF Radio's on a USRP B210

[Joaquim Broquetas Ruiz]

Hi Henry,

The B210 is a two-channel SDR radio, with the ability to select between the
TX/RX and the RX2 ports for the receive signal source. In order to use both
radio channels, you need to set the number of downlink and uplink antennas
to 2 in the GNB configuration file. You can do that by setting *cell_cfg ->
nof_antennas_dl *and *cell_cfg -> nof_antennas_ul *to 2 in your
configuration file. Please, be aware that using both channels restricts the
available sampling rates to a maximum of 30.72 MHz.

I suggest checking that the duplexer you intend to use has sufficient
isolation from the TX path to prevent damaging the RX path of the USRP.

Regards,

Joaquim.
