[USRP-users] Phase unstable even with MIMO cable

I'm observing an unstable phase when I'm transmitting and receiving a constant value over a wire. Is that normal, or is something wrong with my HW or configuration?


I assumed that since the channel is fixed, and USRPs are synced, that I'd see a constant phase.


I'm using 2xN210s with WBX boards in them, and a MIMO cable to connect/sync them. Sampling rate is 2Msps. Flow GRC and image attached.


Thank you,


AB
