Description Network Time Server with High Precision OCXO for Beidou Dual Mode GPS PTP Clock NTP Server (30m Antenna + 9 Network Port) Description: - MA-802 series time server is a high-precision, highly concurrent and multi-functional satellite time synchronization device, which can support multiple time synchronization protocols, including NTP, PTP, IRIG-B code, 1PPS, RS485 and RS232 output. It adopts high-quality professional domestic clock timing chips, ensuring high-precision clock synchronization, supporting up to nine 10/100M adaptive Ethernet ports, and physically isolating each other. NTP synchronization accuracy is better than 1ms. In terms of high concurrency, the time server can process about 30000 times service requests per second, providing efficient time synchronization support for your applications. - This series of time server are configured with WEB web page management, which can view and configure the device status without installing software on the computer. At the same time, the device also supports the SNMP v2 network management protocol and multi machine hot standby function. - The Time server adopts 1U rack design, with beautiful appearance and easy installation. In addition, it is equipped with a 4.7 inch VA color screen, providing an intuitive and easy to understand interface. Users can monitor various states of the Time server through the screen, which is easy to use. Features: - Satellite upgradation: for Beidou, GPS, GLONASS, GALILEO - Interface upgradation: NTP, PTP, IRIG-B, 1PPS, 10MHz, TOD - Performance upgradation: concurrency per second is better than 30000 times - Network port upgradation: up to 9 network port (optional) - Screen upgradation: 4.7-inch color screen Specification: - Supported satellite: for Beidou, GPS, GLONASS, Galileo - Performance: NTP request volume: 30000 times/second Timing accuracy: better than 1ms - High precision OCXO: Stability (ppm): ±0.1 Annual aging rate (ppm): ±0.1 Time deviation after 1 day of lock loss: ≤400us - Network port number: 1/2/3/4/5/6/7/8/9 (optional) - Supported interface: NTP/PTP/1PPS/IRIG-B bit/10MHz/TOD - Others: support IPV4/IPV6, support binding multiple IPs to a single network port, support up to 5 devices with multi machine hot standby, support WEB web page management, support SNMP network management protocol, support WEB remote firmware upgrade. Security Guarantee: - Support NTP MD5 authentication: used to provide authentication for NTP packets exchanged between NTP servers and clients. - Support NTP white list configuration: only NTP client terminals listed in the list can synchronize with the Time server. - Support for WEB whitelist configuration: It can prevent unauthorized access and malicious behavior, and improve system security. - Support time security range setting: When the error between the superior time source and the local machine exceeds a certain range value, its time will not be synchronized. - Support for fault sound alarm: It can detect and handle abnormal situations in a timely manner without the need for manual monitoring. Precaution: - The main difference between ordinary and constant temperature crystal oscillators is that when there is no time reference (such as antenna damage), the constant temperature self timing is more accurate and the deviation between seconds is smaller. The time accuracy of the two is exactly the same when there is a satellite signal. - If you have nanosecond level high-precision timing requirements such as PTP, B-code, PPS, or need to rely on a time server to maintain long-term accuracy, it is recommended to choose a constant temperature crystal oscillator version.
