Hi Marcus, I forgot to say that the two USRPs are on different computers... Do I still need to have mb1 getting the external clock? thanks Achilleas ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-use

This will semi work. You won’t get useful phase alignment between the streams. Sent from my iPhone > On Mar 3, 2019, at 12:41 PM, Achilleas Anastasopoulos > wrote: > > Hi Marcus, > > I forgot to say that the two USRPs are on different computers... > > Do I still need to have mb1 getting the

Hi Marcus I am not interested in phase allignement but only frequency alignment. This is EXACTLY what I have observed in my successful experiment with the N210s and the MIMO cable. Is there any reason why this setup will not produce what I have described? Achilleas On Sun, Mar 3, 2019 at 2:

Same daughtecrards on both? Same UHD version? Can you check with a scope the presence of 10Mhz on the ref out? Sent from my iPhone > On Mar 3, 2019, at 2:46 PM, Achilleas Anastasopoulos > wrote: > > Hi Marcus > > I am not interested in phase allignement but only frequency alignment. > > Th

Thanks Marcus. Sorry I am new to USRP, so the USRP X300 has to work with a separate daughterboard? I had a USRP B200mini before, which can collect a single channel data but overflow gave me a lot of trouble. So in terms of daughterboard, is TwinRX daughterboard good enough to fulfill this require
