Hi,
Currently the sample rate is set to 20e6 just for testing. Later we will change
to 100e6 when this works. So please first help us to stream two channels
simultaneously using this sent code and refer to README. Still if you have any
problem in running the code then let me know.
Also I am
Hi,
I am using UBUNTU 18.04.
I am attaching a link. Visit that link to get the C++ code.
Thanks for all the info, I think I am starting to wrap my head around all of
this. So I did some more digging and have found some discussions on Transmitter
LO leakage (LOL) that suggest creating a cancellation signal by applying dc
offsets to the transmitters inputs. By doing this, would this

Just to get some perspective, those levels are about 6dB *below* the
limits of CFR 47 Part 15 for *radiated*

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

Hi all,
I am using two USRP X310s to transmit signals on 2 channels. The two USRP
are synchronized through a octoclock-g.
A multi_usrp object is used to control those two USRP, device address is
set to addr0=192.168.40.2,addr1=192.168.60.2. I want to set two USRP
transmitting signal at RFA at
Marcus,
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
Hello Sourin:
Could you share your C++ program, so that we might try to reproduce the
problem here?
Which version of Linux / Ubuntu are you running?

Hi,
I am using UHD-3.14.1.0
I am not using gnuradio now. I used that one year back and faced the mentioned
problem. Now I am using c++ code and am facing the same issue of not able to
stream two channels simultaneously.

Hi,
I am using USRP 2955 and want to receive two channels at 100 MSPS each
simultaneously. I have connected usrp with PCIe. I am running my code but only
one channel is getting received. Other channel is sending zeros only. I am
