Product Description

NetWork Time Server

The ptf 3223ANetTymeTMprovides Stratum Iaccuracy for your enterprise network installation.Time acquired via the GPS antenna is distrib-uted using the TCP/IPNTPto network worksta-tions. Synchronization over the network takesplace in 1 to 5 milliseconds.

By applying today's advanced GPS technologyto address the growing need for providing accu-rate network time, the ptf3223ANetTyme deliv-ers precise time via an Ethernet interface usingthe network time protocol standard common inmost computer systems today. (TCPand UDPare also included).

The ptf3223ANetTyme uses at its heart a high-ly advanced, 12 channel GPS timing receiver, todeliver milli second accuracy to the network.

In addition to NTP, the ptf3223 NetTyme sup-ports a number of network management tools tokeep your network in sync and working for you.

Other standard features include high precision 1PPS and IRIG-B outputs (via BNC) for time syn-chronization and time display applications.
