Phase&frequency synchronization of two USRP1

GNU Radio
1

Hi everybody,

just in case somebody has already been doing it.
What is the best way (if any) to phase&frequency-synchronize two USRP1?

No need to lock them to an external reference. Just need to have the
same
instantaneous reference clock on both.

thanks and regards to all the list

Hello Vince,

for USRP1’s, freq and phase synchronization can be done using pll costas
loop and clock recovery blocks. Just check these programs for reference
(gnuradio-examples/python/digital-bert/benchmark_tx.py and
benchmark_rx.py).
