Name: SHTS2000 Satellite Synchronization Master Clock

Model: SHTS2000

Product introduction

SHTS2000 satellite synchronization device is a high-precision and high-reliability synchronization device specially provided by Shenzhen Shuanghe Electric Co., Ltd. for time synchronization network. It takes high-precision satellite time as the time source and adopts advanced "time taming algorithm" to complete the perfect combination of long-term stability of satellite time and short-term stability of crystal oscillator time. At the same time, a simple and powerful man-machine interface is designed for customers, and various time signals can be selected as interface cards. The system can be equipped with a WEB server to provide remote or local monitoring software to realize the network management function.

The system can adopt various time reference signal redundancy and power supply redundancy to ensure the reliability of the time service system; The hardware real-time parallel processing of time scale ensures the accuracy of timing; Modular output interface is adopted to ensure the flexibility of timing; Can be expanded into multi-channel time information according to customer requirements. Powerful and convenient remote network monitoring function, management software based on WEB technology, convenient for users to manage.

main feature

1. Dual-configuration synchronous clock independently receives satellite time, and the external reference time is optional, so that the time reference signals are mutually backed up.

2. Support NTP, SNTP network protocol and RJ interface, which can realize network time synchronization.

3. The standard time code transmission can be set to compensate the transmission delay, so that its time scale transmission is not limited by the distance medium.

4. Powerful remote or local monitoring software makes management and monitoring operation simple and easy, and realizes network management.

5. Various output signals can be output as plug-ins, such as 1PPS, 1PPM, 1PPH, IEEE 1344 or NASA36 IRIG-B code, DCF77, SNTP(RCF 1305). At the same time, each signal (except network and message) has the function of online programming RS-422/485, empty contact, 24V active, TTL and other electrical interfaces.

6. Powerful signal alarm function. The operator can see the alarm reason and alarm solution from the monitoring software or the display screen of the equipment.

7. Built-in rubidium atomic clock or high temperature constant temperature OCXO for customers to choose. Advanced taming algorithm is adopted to output high-precision local timing.
