Dear all, We make synchronization between two N210(both of them with ubx40) with MIMO cable.When we restarted program,the phase offset would changed 180°(no other values) regularly. Do you have any suggestions? thank you. best regards Jon

Dear Jon, as per http://files.ettus.com/manual/page_sync.html#sync_phase_lo , phase sync with UBX is only 100% possible on the X3xx platform, not on N210 – as far as I remember, the 180° (==sign) ambiguity is what stops us from saying "it's fully supported". There's no hardware remedy to this :( you'll have to circumvent that, possibly by estimating the correct sign in software, if what you're trying to do allows that.
