Hi,
I have 2 USRP N200 devices equipped with an SBX daughterboard each. I also have a function generator to provide PPS and 10MHz reference signals, to both USRP devices with equal length cables. The problem is that I want to synchronize the 2 SBX daughterboards, so that I get a consistent phase measurement everytime I run my code. What I mean by consistent phase measurement, is that I want to be getting more or less the exact same phase measurement in the static environment where I perform my experiments. And I want to be getting that same phase measurement even if I power-cycle the devices (i.e. turn them off and back on again ). I need to have reproducibility. I have tried various instructions found in the knowledge base of Ettus and around the internet like in the mailing-lists or on stackexchange but unfortunately nothing has worked for me so far. I managed to kill the CFO between the devices, but I still haven't managed to kill the phase difference between them. Feel free to ask me any questions that might help solve my problem. Thanks in advance. Konstantinos?
