Description
The TM2500D (Time Server with 1PPS/10MHz Frequency Output) is an upgraded TM2500C and is the latest addition to our NTP/PTP GPS time server product line. Based on the upgraded processor of the TM3000A, the TM2500D, like our other GNSS 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 GNSS, and manual time setting modes. The TM2500D uses an active GNSS antenna to maintain the current time as broadcast by GPS, GLONASS, Galileo, and BeiDou 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.
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 time 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 demands. For the best GNSS time server 10MHz frequency synchronization performance, an outdoor antenna is highly suggested.
Actual Product Size: 4″ x 1⅜” x 4¾”
Included with each TM2500D purchase:
12V Power Supply • GNSS Patch Antenna • SMB to BNC cables (2) • Quick Setup Guide • Rubber Grips • 10MHz reference signal test report (printed copy).
