Hi Akin, The Octoclock-G would be suitable for this purpose, and yes, it does contain a GPSDO (OCXO). https://kb.ettus.com/GPSDO#GPSDO_.28OCXO.29
The Octoclock-G does not contain an antenna, you must provide one to the GPS Antenna input (SMA). The X3xx series do not support IEEE 1588, however, the N3xx series USRPs do support White Rabbit, which is an extension of the IEEE-1588-2008 standard. More info can be found here on it https://kb.ettus.com/Using_Ethernet-Based_Synchronization_on_the_USRP%E2%84%A2_N3xx_Devices Regards, Nate Temple On Wed, Feb 27, 2019 at 8:31 AM akin soysal via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello All, > > > I have a question.
