Hello All, I have been running tests in which I am transmitting a signal from one USRP X310 that's using a UBX 40 daughterboard, and that signal is being received by another USRP X310 using a UBX 40 daughterboard. I have noticed that when I have the receiving USRP running with the Gnuradio flowgraph active, as soon as I start the transmitting USRP's Gnuradio flowgraph, there is a jump in the noise floor as it is seen by the receiving USRP, and its roughly a 14 dB increase. This occurs even if I have the signal being transmitted muted. Does anyone have any idea what the source of this added noise could be? It is something that I need to mitigate as much as possible for the tests I am running using these USRPs. Any feedback will be greatly appreciated, thanks!
Best Regards, Jerrid
