Dear Robin,
Thanks for the quick reply. Although the 180-degree ambiguity is
already good to know, what we are observing is really some rotation in

Does the LO lock happens fast? Or should I
for the PLL to lock?
Thanks,
François

The Analog Devices AD9361 RF integrated transceiver in the B205mini has a
divide-by-2 PLL inside when using an external reference input, so there
will always be a 180 degree phase ambiguity.

Dear all,
Im having a problem synchronizing two USRP-B205 mini.
The setup is as follows: I use one USRP as a transmitter, the other as a
receiver, and they are connected by cable. The ref input of both USRPs is
connected to a 10MHz output (also tried with PPS output) of an Octoclock. I
