Hello, I want to measure the phase difference between three synchronised USRP channels (Common Ref & PPS), does software exist to do this, and to what accuracy, please? Sorry, this is a bit of a newbie question, and probably already covered!
Sure, the easiest way would simply be to put in a scope, and check by looking -- of course, that's not very accurate.
There's enough math operators in GNU Radio to see the actual phase difference, such as conjugate and multiply, then convert to phase.
