[Discuss-gnuradio] sbx board realize RF1 send and RF2 receive simultaneously

Hi,

       I'm now using the usrp n210 and the sbx board.My question is:how to implementation the function that RF1 send and RF2 receive simultaneously in the grc?

Just add the "USRP Sink" and "USRP source"  block in one grc and choose the antenna "TX/RX" and "RX" respectively?Is this a synchronization way?

      Thanks.

Best regards,
