Question about duplexing with USRP


#1

Hi, everyone,

Right now I’m doing some FDD work with USRP and flex2400. For one USRP,
I
transmit signal at 2350MHz and receive at 2450MHz.

From the received waveform I found that the transmitting program interrupt
the receiving script. The received cosin wave turned out to be
incontinous.
But when I stop the transmitting program, the received waveform became
normal.

In the transmitting program, I use set_auto_tr(False), in the receiving
program, I use set_auto_tr(False), too. Is that correct?
I found that if I use set_auto_tr(True) in transmitting program, the
transmitting power is degraded by receiving program.

Is it possible to make the transmtting path and receiving path work
independently without interrupting eachother, and how? I really want to
know
that.

Thank you!

Forgot to say, I’m using one port TX/RX for transmitting and receiving
simultanously, is it OK?
