GPS NTP+PTP Network Time Server + 10MHz Output (TM2500C)
$799.99
The TM2500C time server is the newest addition in the NTP/PTP GPS time server product line with the same great features, improved holdover accuracy, and reliability of the TM2000B, but includes additional reference output capabilities that our customers have requested. Now both 1PPS and 10MHz reference signal outputs can be obtained from the dual SMB connectors on the TM2500C. Time serving accuracy is key. TimeMachines® delivers a quality gps time server product at a very reasonable price for your network infrastructure!

Description
The TM2500C (Time Server with 10MHz Frequency Output) is an upgraded TM2500B and is the latest addition to our NTP/PTP GPS time server product line. The TM2500C, like our other GPS NTP servers, provides a Stratum 1 time source on the local network with no need for an internet connection. SNMP V2/V3 is supported on the device, authenticated NTP, peer NTP lookup, IPv6, PTP without GPS, and manual time setting modes. The TM2500C uses an active GPS antenna to maintain the current time as broadcast by United States’ GPS satellites worldwide. In addition, a high stability OCXO reference clock is included that allows the unit to serve time if GPS lock is lost for periods of time.
The additional processing that was added to the TM2500B to provide a greater accuracy for holdover time is also included on the TM2500C. A pair of SMB connectors on the back of the device provides both 1PPS and Synchronized 10MHz reference frequency output signals simultaneously. With this powerful feature set, the OCXO reference clock with improved holdover accuracy, and reference outputs, you cannot beat the price and capabilities of this GPS NTP server device. It is a small gem that adds so much to your network capabilities. This unit is suitable for scientific measurement, simulcast radio system clocking, and many other high accuracy demand uses. For the best gps time server 10MHz frequency synchronization performance, an outdoor antenna is highly suggested.
Included with each TM2500C purchase:
12V Power Supply • GPS Patch Antenna • SMB to BNC cables (2) • Quick Setup Guide • Rubber Grips • 10MHz reference signal test report (printed copy).
