This is not quite right. The DIFFERENT oscillators on the USRP boards
have different frequencies and thus constantly changing phase angle with
respect to each other and with probability 1, the frequencies of both

way to avoid this is the buffer the clock from one board and use it to
drive the other board.
Maybe you missed this line:
I export the 64 MHz clock from the master usrp and input this as clock for the
slave usrp.
So I do drive all boards from a common clock.
he system will NOT be coherent unless it IS
coherent. ;-)
Well, I think it IS coherent.
