NS8004 PTP/SyncE Time Server and Timing Reference

NR8004-PTP/SyncE

Small Form Factor, Low Cost Time Server with Dual-Channel GNSS-Locked 10 MHz OCXO Reference

A low cost high performance timing reference in a compact chassis (90mmX120mmX27mm) that can be shelf or rack mounted (rack mount kit available). The 2 analog and 2 digital outputs can be independently user-selectable for IRIG, 10 MHz sine, PPS, or square wave (10Hz – 50MHz). Timing that is accurate in the tens of ns. PPS leading edge can be locked to the 10 MHz in 5 ns steps.

The NOVUS NS8004 delivers precise time and frequency synchronization for laboratories, telecom systems, power utilities, and secure networks. . With integrated SNMP monitoring, Ethernet access, and front-panel status indicators, this NTP time server ensures continuous operation and simplified system diagnostics for demanding applications.

FAQ

1. What happens if GNSS lock is lost?
   Auto-calibration applies stored compensation coefficients, maintaining OCXO stability (5 ppb/day typical) until lock is restored.
2. Which satellite constellations are supported?
   The system tracks GPS, GLONASS, SBAS, and QZSS to minimize lock time and enhance reliability.
3. How does the dual-time base option work?
   It adds a second GNSS receiver and gapless counter that continually verifies the 10 MHz reference and warns of tolerance drift.
4. What connector options are available?
   Choose between BNC or SMA outputs; a kit with an active GNSS antenna is also available.
