Here's a late model (Microsemi Branded from 2015), used Symmetricom SyncServer S250 NTP server that obtains highly accurate and traceable time from the GPS satellite constellation - as well as IRIG-B, 10MHz and 1PPS inputs if preferred.
This is the DC Power version that can accept power in the range 40-60V DC (48V most commonly). No AC to DC power supply is included. The unit has been tested (screenshots below) and confirmed to work fully. The cosmetic condition is very good and the display is bright and clear as you would expect from a recent unit - the photos show the actual item for sale.No antenna is included but I have the matched 12V AT575 antenna available in a separate listing, and/or can edit the listing to include one if required. Note that the antenna voltage is 12V so you cannot use one of the generic 5V antennas commonly offered for sale. For best results the antenna needs to be mounted outside with a complete view of the sky. It ships set to the factory logon defaults (admin:symmetricom) ready for your install.
This unit has the TCXO internal oscillator. The installed firmware is v1.36 which is the latest version available at the time of listing. Listing comprises the items you see in the images only.

It is Next Generation ready to be the synchronization source for multiple applications. Multiple and Versatile Timing Configurations. It smoothly transitions from one reference to the next available if the higher priority signal is lost or regained.
This is perfect for operating with different backup time or frequency sources. The S250 can also revert to a Stratum 2 mode and retrieve time from other user-designated time servers.Easy To Set Up and Maintain. SyncServers are the easiest to set up and maintain network time servers in the world.
The front panel of the SyncServer S250 is designed to quickly bring the server online with a few front panel keystrokes or DHCP. To fully configure the unit, use the very intuitive web interface or the step-by-step wizards for the most common operations. The S250 provides reliable and secure network synchronization technology by combining multi-port, high-speed/ high-capacity network interfaces and versatile GPS timing receiver technology. The multiple ports of the S250 provide the flexibility to adapt to different network topologies as networks grow and change. It supports a wide range of network protocols including IPv4 and IPv6, for easy management and seamless integration into your existing and future network.
The high speed processor and a nanosecond clock assure high bandwidth NTP performance for hundreds of thousands of network clients. The Stratum 1 level S250 derives extremely accurate time directly from the atomic clocks aboard the GPS satellite system. Reliability is further enhanced via Stratum 2 operation by retrieving time from other user-designated time servers.
All SyncServers can be upgraded to an internal Rubidium atomic oscillator to keep the time server accurate if the GPS signal is lost. Customer Tested Time Server Design. The 5th generation Symmetricom SyncServer S250 has decades of design experience behind it.
