If you really can't handle any LO leakage, can you switch off-frequency
between times you want to transmit?

Ok that makes sense, I thought it might be something to do with the mixers and
leakage, but I wasn't sure. So I have tried lowering the gain to 0 dB, and
there is no change in the signal. The signal does cause problems as I am
working on a GPS related application, so even though -100 dB

I apologize for the delay in response, but I was able to solve the problem I
was having with sending a signal at frequencies above 1.3 GHz. Turns out, in
one of the two USRP's I am using for my project, I managed to get the cables
for TX/RX and the RX2 flipped around when I set ev

Hello All,
So I have been running into some interesting issues lately with using
a USRP X310 as a signal generator. I have a UBX 40 Duaghterboard
installed in the USRP, and I have been testing sending signals at
