Hello,I am trying to run a loopback test where I am using the USRP2 and the FLEX900 daughter board. I have connected the TX/RX port directly to the RX2 port. I am running usrp2_siggen.py as is (presumably transmitting out the TX/RX port) and then also running usrp2_fft.py. I tried to modify usrp2_fft.py so that I could switch the receive port to RX2 as follows "self.subdev.select_rx_antenna('RX2')" - actually pretty much just uncommented out the code that was already there. However this does not seem to work. I wonder is there anyway that I can preform the test I want to. Is there anyway to get the USRP2 to transmit out TX/RX and at the same time receive from port RX2...any help would be greatly appreciated.
Yes, you can do full duplex, but you should not connect the ports directly or you will blow out the receiver. There will be enough leakage that you can just put attenuators.
