Brandywine precise time protocol instruments

The Brandywine range of dedicated instruments uses the IEEE1588 precise time protocol (PTP).

PTP, described in the IEEE 1588-2008 version 2 standard, enables precise synchronisation of networks with an absolute timing accuracy of better than 100 ns to coordinated universal time (UTC), using hardware-generated timestamps. This provides significant improvements on the accuracy of network-distributed time over network time protocol (NTP) servers.

The PTP Slave Network Time Client provides network service providers and equipment manufacturers with a packet-based timing and synchronisation solution.

The PTP80 GrandMaster Clock generates and distributes precisely synchronised time across packet networks. The functionality of the clock is also available as an Option 80 PTP module, compatible with the M210 and M211 modular timing system.

The TimeSpy Elite and Elan portable network time analysers can both accept PTP input (as well as a wide range of other inputs) and check it against UTC.
