Hello Muhammad Shahmeer Omar,

with neither an external signal or a GPSDO, this is physically impossible.

I think with external signal you mean the PPS signal; you can of course use a reference signal and build synchronization in software. That is a problem equivalent to synchronization in communication systems, e.g. synchronization of mobile phones to a base station.

Best regards,
Marcus Müller

Hello all,

Ive been trying to achieve transmit time synchronization for over a month
now using GNURadio and USRP B200, and so far i have had limited success. I
could not find alot online. My question is simple. Is it possible to
achieve synchronization between two USRPs without using an external signal
or the GPSDO?

If so a little guidance would be much appreciated. Thanks.
