NTS-4000 OCXO NTP/PTP Server

STRATUM1 NTP & PTP MASTER

 

  NTS-4000 is STRATUM-1 NTP server and PTP/IEEE1588 MASTER. It delivers precise time directly into LAN using NTP/PTP* protocol. Referential UTC is drawn from GPS & Glonass, Beidou*, Galielo* simultaneously. Product can be equipped with 2 independent redundant GNSS (GPS/Glonass) receivers and two redundant power supplies. Product includes basic surge/overvoltage protection. In case of losing SAT signals, the NTS-4000 disciplines itself from internal high performance OCXO, working weeks in holdover mode w/o GPS. To compare NTS-4000 to other ELPROMA product click here.

NTS-4000 is equipped with 2x LAN It also includes: 1PPS in/out, 10MHz out and IRIG-B in/out.
 

Server supports Sysplex, and GPS NMEA output emulation. NTS-4000 is ready to work 24/7 for years.
