Hi,
I have written a code for simultaneous TX/RX for RFX2400 as
followed below:
self.rx = usrp.source_c (0,self.decim)
self.tx = usrp.sink_c (0, self.interp)
.
.
.
fg = my_graph()
.
.
.
fg.subdev.set_enable(True) # Enable transmitter
fg.connect(fg.rx, fg.tx)
.

When I receive and then transmit, the waveform distortiton is very
high on transmit path. I used different combination for decimation
and interpolation rates, but that didn't work.
From your description above, you are transmitting whatever you
receive (is this true?).
I am recieving a sinusoid wave using RX2 port on 2.40GHz and
transmitting using TX/RX port on 2.48GHz.
I'm guessing that the sinusoid is coming from a waveform generator,
or something. Are you selecting the RX2 antenna?
(subdev.select_rx_antenna("RX2")) are you using a multiplication
block on the transmitter? What are you setting the Rx PGA gain to?
Can somebody tell me about the reason for distortion?
Thanks in advance.
