[Discuss-gnuradio] FLEX900 RX2 Port
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.
Thanks,
Sharif

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.

Re: [Discuss-gnuradio] FLEX900 RX2 Port
Hi Matt,
Thanks for the advice, but might you know how I can configure
usrp2_fft.py to
use port RX2, as i had mentioned, augmenting usrp2_fft.py in the fashion
I described does not work. For that matter, might you know in general how
to direct reception to RX2 instead of TX/RX which I believe is the default.
Thanks,
Sharif
