Symmetricom introduced a GPS referenced grandmaster clock and IEEE 1588 measurement and validation tool supporting Precision Time Protocol (PTP) Version 2. The solution provides ultra-precise time and frequency synchronization over Ethernet networks.
Symmetricom’s XLi IEEE 1588 Grandmaster contains a dedicated 1588 time stamp processor and functions as an IEEE 1588 slave with the ability to measure PTP client performance by assessing time transfer accuracy across a network.
