USRP-2943 sync daughter boards on a single device

I am interested in getting phase aligned input from RX1 of channel 0 and 1 (two daughter boards), but unfortunately they are time but not phase aligned. Can both be aligned to have a zero phase difference on acquisition?

Hi amir13,

 

If you want to get a zero phase difference between input signals from channel 0 and 1, you need to implement an algorithm to measure the phase difference and calibrate it with a reference signal.

 

Thanks

Thanks for your guidance. How do you suggest I can calibrate? Because there is no way external signal can be switched from calibrated signal to normal input without restarting usrp.
