3223A NetTyme Network Time Server

The ptf 3223A NetTyme provides Stratum 1 accuracy for your time synchronization application. Time acquired from the GPS constellation is distributed using a TCP/IP Ethernet connection and Network Time Protocol (NTP), from the 1PPS output connector, or from the IRIG B time code output. Synchronization using the NTP capability is accurate to within a few
milliseconds, while the 1PPS and IRIG B outputs provide accuracy levels in the order of microseconds. The unit is ideal for integration into a variety of synchronization systems, including power generation synchronization systems that also require
NTP. The unit also incorporates a special Serial Print output providing day of year and time of day on a dedicated RS232 port
