Thats correct. When each USRP has its own ethernet link, the MIMO cable is only used for clock and time signals. > > * * > > *Next, I retained the MIMO cable, set the Master USRP’s clock source to > external and have a 10MHz source connected to the Reference input.

Yes, you can split 10MHz and PPS signal to all 4 units. -josh _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
