Hi all,
Had posted about this before, but focusing on 1 simple case here. I'm observing a change in a wired channel every time I restart my flow graph. I'm using 1 USRP + WBX board, i.e. tx and rx on the same USRP. So time/frequency sync should not be a factor, I believe. I simply do: start-> sleep(2)-> stop->wait->start->sleep(2).... looped 10 times, and record the rxed signal. I see that during the 2 seconds the channel remains constant, however after the restart the channel changes. Any ideas on why this is happening? I was expecting to see the same channel no matter how many times I restart the flow or even power cycle the USRP. Figures attached: Real and imaginary part of rxed signal, subsampled ~110 to fit it all in. Thank you, Arjun
