Re: [USRP-users] time/phase synchronization of 2 X300

Hi Luca, Any external 10 MHz and 1PPS source will work. The 1PPS is basically a DC signal so it is best to have a buffer amplifier to split it, but if just going to two USRPs you may be able to get away with using the RF power divider as well. The required signal levels are posted in the user man

Hi Marcus, What about to use an "external" GPS Timing receiver with PPS and 10 MHz output and to split them using power divider to provide pps and ref to the 2 X300 ? I do not want to use the octoclok for space saving reasons. Thanks, Luca > There has never been really-good support for REF O

Hi, is it possible to phase synchronize 2 X300 as follows: - X300#1: equipped with GPSDO. Generate Ref and PPS signal for the X300#2 via PPS out and Ref out connectors. - X300#2: take PPS and Ref Signal from X300#1 (daisy chain) Target daughterboard is TwinRx. Phase offset will be corrected by
