I believe if you have two daughter cards it is possible to run the benchmark_*x scripts on the same USRP but different daughtercards, but I think you need to combine them into a single flow graph. If I remember correctly when you open a new instance of usrp_source_* (as you would when you run the second script), the settings for the old one get wiped out. One thing to note here is that with the leakage from the cards themselves (caveat, I have not used the RFX1800) it is very likely that you will get an excellent BER even without antennas. For example, even with both the transmitter and receiver ports terminated, I still receive a very high SNR waveform when listening from one card and transmitting from the other in a single USRP. Based on my experience with the RFX2400, if you are planning to use this to attempt to model some sort of communication system, your antenna choice/interference will likely have little impact on your results. If you simply want to 'see it work' then the single USRP set up should be fine, however for any real testing you will probably need two USRPs.
