Hi,

I am slightly confused on the USRP configuration.  The spec sheet says there 
are 4 input and 4 output channels.  Assuming you use two LFTX, and two LFRX 
daughter cards, it makes sense that you have 4 input and 4 output channels 
since each daughtercard has a jack labelled A or B.

For IQ sampling with an individual antenna, would I connect the leads of the 
antenna to an A and B channel on the LFRX for receive, and an LFTX A and B 
channel for transmission?  
To do simultaneous transmit and receive, would some type of external switching 
circuit be required?  If not, how would I go about doing this?


Thanks,
Dan
