I think it depends on what is meant by the “same phase as last time”. Relative to what? Sent from my iPhone > On Mar 14, 2019, at 10:17 AM, Sylvain Munaut <246...@gmail.com> wrote: > > Hi, > > integer-N tuning maybe ? > And use the DDC/DUC for the rest ? > > Cheers, > > Sylvain

Hi, integer-N tuning maybe ? And use the DDC/DUC for the rest ? Cheers, Sylvain ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com

Re: [USRP-users] Phase after Freq Hopping

That kind would be cool ;) . But: since this is radar, the reason for all this is probably exceeding the Nyquist bw of the DAC with the radar wave form :( Cheers, Marcus On Tue, 2019-03-12 at 23:49 -0700, Ian Buckley via USRP-users wrote: > > On Mar 12, 2019, at 3:05 PM, Marcus D. Leech via USRP-

[USRP-users] Phase after Freq Hopping

Hello , For a Radar I´m transmitting and receiving with the USRP X310 samples on different frequency steps. For instance, after 4 frames I´m coming back to the first center freq and continue this a few times. Hope the following description helps… f3 |phase4| |…| f2
