Hello,
I am a little confused about the naming regarding the TX/RX ports on
the Ettus N321/N320. If I specify a channel(i.e channel 0) for
receive, does that mean RX2 will be active, or will TX/RX port be
actively receiving? And if TX/RX can recieve, does that mean the
N320/N321 has up to 4 RX channels?
Thanks
Joe

Any given RX channel can either be connected to the corresponding RX2
*OR* TX/RX port. A TX channel can only ever
be connected to its corresponding RX/TX port.
It's just an antenna switch for a receive channel. For half-duplex
communications techniques it's often the case that a
single antenna is used and alternates between TX and RX when required.
