I think you will find that +/-50nS
This is a very good point. Indeed my application is not in the same band as
GPS. I'll spend some more time to familiarize myself with the B210!

It has 2 RX chains with a single LO, you need to receive the _same_
frequency. (at least within the same RF bandwid
Each B210 will have a GPSDO, they'll be separated by a few kilometers. My
understanding is as follows:
1) When each B210 syncs, the 1PPS pulse between each USRP would be aligned
to +-50 nsec. Since they're only separated by a few km, I suspect the
alignment might be better because of common errors

Hi All,
I'm looking at using multiple B210s synchronized with GPSDO distributed
over a few kilometers. The idea is to measure time-of-arrival of a signal
source. I understand the limitations of the GPSDO 1pps & 10 MHz reference
frequency/time stability.
What I'm curious about is whether anybody h
