Hi Marcus, Yes, I am following the link and using an external 10MHz and 1pps reference signals. The way I am trying to synchronize is to have two usrp's transmit different sine waves one with constant phase and the other with a varying phase from 0 to 360degrees. I am calculating the sum of amplitudes of the received signals and the phase at which the amplitude sum is maximum will be the phase offset. By following this approach I am getting a phase offset between 0 to 3 degrees. But when I issue the next stream command with sine wave of calculated phase offset I am seeing a huge phase difference between them anywhere between 0 to 180 degrees for each run. I am not sure if my approach is a correct one.
Thanks Aravind.
