Hi Matt,
Thanks a lot! So, you means I just need connect between Tx/Rx and leave Rx2
unused for RFX 900. But I want to implement FDD (frequency division duplex),
it should use Rx2. Do I need to make change to hardware? how?
Thank you!

I use two sets of USRP with RFX900 to test a FDD( frequency devision
duplex) by cable connection. According to my experience, the

I am wondering why there are two switches in the RFX series daughter from
schematics. It seems their purposes is different: one for switch between Tx
and Rx, another switch between Rx and Rx2. So, my questions as:
1. we may use one tx and rx enough, why need to use two Rx?
2.I follow the python co
