The XHTF351P-S PTP slave clock device is a high-precision clock node device that can be used for time synchronization networking. It is mainly synchronized with the upper PTP master clock device through the IEEE1588-2008 protocol, generating a variety of time-frequency signals using external or internal high-stability frequency sources.
The XHTF351P-S provides the user with a 10MHz beacon signal, a 1PPS sync pulse and an IRIG-B time code. Can be widely used in communication base stations, high-precision network time synchronization and scientific research calibration laboratories.
Features
● Support the IEEE1588-2008 protocol;
● Can receive Beidou or GPS independently;
● Modular design of the whole machine, easy to operate and convenient to maintain;
● Complete SNMP network management.
