And to add, the possible bandwidth is even 61.44 MHz with the B210. The
attenuation at the band edges gets a bit higher with this mode, and it is not
too clearly mentioned in the AD9361 specs, but I am using the B210 with this
setting and have no issues with it. This clock appears being a tribut
Dear Marcus,
1. TCP works fine for my application if I am not using selector blocks. It
creates problems with selectors only for my flow graphs.
2. I have used the method of multiplying the flow with 0 or 1. It taxes
double the processing. Processing does matter when applying filters and FFT

USRPs can do Tx and Rx at the same time. I did an experiment where I
modified the FPGA image of Node 2 to send the Rx samples directly to Tx on
a different freq., and measured the phase difference of the echo from Node
2 at Node 1. I didn't measure the phase difference of the carrier, rather

Jason,
This is perhaps a long shot but I noticed that your code does not include
set_thread_priority_safe() for each thread - only the main thread. Perhaps
adding this will help. I realize that this does not explain why you are
successful when not using the same channel.
Also, I noticed that the

Hello,
Can you please paste a copy of the full output, including the command, for
uhd_usrp_probe? That will include a lot of information which we can use to
offer advice.
Thanks,

Hi List,
I'm trying to use X310 and LFRX daughter board on RFNoC frame work.
I attached UBX and LFRX boards on X310 and run command "uhd_usrp_probe" and
found that the app didn't detect antenna of LFRX, so my app can't show
signal from it.
Could you help me, please?

Dear Erik,
in general: No, but in a specific Up/Downlink scenario, it might work.
To explain:
The B210 indeed has two RX chains, but they are both mixed with the
*same* LO. That means that the spectrum you get can only be within the
analog bandwidth around that LO at f_RF:

Hi List,
I would like to capture GSM downlink and uplink signals with USRP B210.
I have done this previously with 2 units of USRP and connected via MIMO
cable. My question, is it possible to perform this activity with USRP
B210, which already have 2 RF channels and do i have to add additional
