The ptf 3223A NetTyme provides Stratum 1
accuracy for your time synchronization
application. Time ac quired from the GPS
constellation is distributed using a TCP/IP
Ethernet connection and Network Time
Protocol (NTP), from the 1PPS outp
ut
connector, or from t he 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 f
or
integration into a vari ety of synchronization
systems,
including power generation
synchronization systems that also require
NTP. The unit also incorporates a spec ial
Serial Print output prov iding day of year and
time of day on a dedicated RS232 port.
