NI-USRP 2922 (1 Transmit and 2 Receive)

[Guzmancb]

I was wondering is it possible for the NI-USRP 2922 device to transmit a signal from tx1/rx1 port while also receiving from the tx1/rx1 and rx2 port at the same time? Is there any code that is possible of doing this as well, I couldn't seem to find an example code in the ni-usrp examples? I would like to be able to see the plot of the signal being transmitted, and also being received from both ports.

i need the same information if you got any information plz feedback us

You can transmit on tx1/rx1 while receiving on rx2 at the same time.  On the Rx session, set the Active Antenna property to "rx2".

However, if I am reading this correctly:

....while also receiving from the tx1/rx1 and rx2 port at the same time? 

You cannot transmit and receive on the same antenna at the same time.

I found the below Diagram in 2920 usrp Data sheet that illustrates the structure of RF Module inside one node and it seems from that structure that it is physically possible too..

That diagram shows that the RX1/TX1 port can be used to transmit or receive, but not at the same time.  The RF Switch at the top left switches between the Rx and Tx signal path.

You can receive on RX2 while you are transmitting on TX1.
