Re: [USRP-users] Direction finding based on USRP E310 board

[Derek Kozel]

Hi Ivan,

The TX/RX and RX2 are ports on the same receiver channel. As Julian says 
there are two receivers, A and B. For a receive only application the RX2 
ports are slightly better performing as they have one less switch that 
the signal passes through.

Regards,
Derek
