With the emergence of synchronization requirements in packet networks, ITU-T has released the profile of Primary Reference Time Clocks (PRTC), which includes the time and phase transmission requirements in packet network. This profile is called G.8272. The original G.8272 recommendations released in 2012 defines such a clock that provides 100ns phase and time performance for packet networks.
Time measurement on PRTC includes absolute time accuracy, relative time accuracy, time stability, time-keeping accuracy, time source and switching performance when equipment has redundancy protection.
Our Instrument can provide a convenient test solution for PRTC time synchronization performance.
