The Symmetricom 1520R-S250-OCXO SyncServer S250 is an advanced, high-performance network synchronization solution designed for mission-critical applications. This device is equipped with an OCXO (Oven-Controlled Crystal Oscillator) and is integrated with U-Blox GPS and NTP (Network Time Protocol) capabilities.
The OCXO component of the 1520R-S250-OCXO ensures high stability and accuracy, providing an excellent frequency reference source. The OCXO is housed in a temperature-controlled oven, which ensures a stable operating temperature, thereby minimizing the effects of environmental changes on the oscillator's frequency. This results in an ultra-low phase noise and frequency stability, making the 1520R-S250-OCXO ideal for applications that require precise time synchronization, such as telecommunications, financial services, and data centers.
The device is also equipped with U-Blox GPS receiver, which provides high-accuracy time synchronization using Global Positioning System (GPS) satellites. The U-Blox GPS receiver offers fast time to first fix (TTFF) and excellent positioning accuracy, making it an ideal choice for applications that require real-time time synchronization.
The 1520R-S250-OCXO also supports NTP, which allows it to synchronize its clock with other NTP servers on the network. This ensures that all devices on the network are synchronized to the same time, which is essential for applications that require coordination between multiple systems.
The device is designed with a robust, industrial-grade housing that is resistant to environmental factors such as dust, humidity, and temperature fluctuations. It also features a wide operating voltage range and a low power consumption, making it suitable for use in a variety of applications.
The Symmetricom 1520R-S250-OCXO SyncServer S250 is a versatile and reliable network synchronization solution that offers high accuracy, stability, and reliability. With its OCXO, U-Blox GPS, and NTP capabilities, it is an ideal choice for applications that require precise time synchronization and coordination between multiple systems.

The installed firmware is v1.36 - the most recent version available. The high speed processor and a nanosecond clock assure band width NTP performance for hundreds of thousands network clients. No un pictured documents or accessories are included. MIB,, Telnet, FTP, and more.
The unit has been reset to the factory logon defaults logon with admin:Symmetricom ready for your install. Cosmetic condition is good - the photos show actual item for sale. To fully configure the unit, use very intuitive web interface or step-by-step wizards for most common operations. Customer input is evident in every detail.
High-Resolution Vacuum. No antenna is included, but I have matching antennae listed separately. Single Satellite Timing. Secure Web-Based Management.
Full numeric keypad. Nanosecond time accuracy to UTC. This is perfect for operating with different backup time or frequency sources. And for best results the antenna needs to be mounted outside with a complete view of sky.
It smoothly transitions from one reference to the next available if higher priority signal is lost or regained. The antenna voltage is 12V so you cannot use one of the generic 5V antennas commonly offered for sale. Dual USB ports. The new card is good for accurate GPS time and date reception until beyond 2037.
Florescent Display. A lightly used, late model from 2015, Micro semi branded fully working SyncServer S250 NTP server that obtains highly accurate and traceable time from the GPS satellite constellation, Screenshots taken during my testing of the actual unit for sale are provided below.
