+SBX Series
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The SBX Series boards have 2 quadrature subdevices, one transmit, one receive.
+Transmit and Receive default to direct conversion but
+can be used in low IF mode through lo_offset in uhd::tune_request_t
+
+The SBX Series boards have independent receive and transmit LO's and synthesizers 
+allowing full-duplex operation on different transmit and receive frequencies.
+
+Transmit Antennas: **TX/RX**
+
+Receive Antennas: **TX/RX** or **RX2**
+
+The user may set the receive antenna to be TX/RX or RX2.
+However, when using an SBX board in full-duplex mode,
+the receive antenna will always be set to RX2, regardless of the settings.
