Overview

Computer networks are omnipresent, and synchronizing these systems is highly recommended across enterprises to ensure seamless operation. Time synchronization enables diverse systems to work in unison, improving overall efficiency and simplifying troubleshooting during fault analysis. By deploying reliable time synchronization solutions, organizations can significantly enhance system performance and reduce diagnostic complexity.

The Sertel NTP Time Server acts as a Stratum 0 server, generating precise timestamp signals to synchronize networks of critical devices such as servers, SCADA, DCS, PLCs, LANs, computer buses, RTUs, and other electrical and communication systems. It supports SFTP over SSH and is equipped with a high-precision, high-stability Rubidium Oscillator, delivering exceptional frequency accuracy of up to 0.1 PPB. The GPS Time Sync Server maintains accuracy better than 15 ns and supports external IRIG-B (AM) input via BNC as well as NTP via RJ45. Time stamps can be transmitted over long distances while maintaining network-wide synchronization, and the system is equipped with anti-jamming and spoofing protection.
