NTP/IRIG Time Server | Low Cost, Triple Channel GNSS-Locked 10 MHz OCXO Reference NS8001-NTP

NTP/IRIG Time Server with Dual-Channel GNSS-Locked 10 MHz OCXO Reference (NR8001)

A low cost high performewnce timing reference in a compact chassis that can be shelf or rack mounted (rack mount kit available). The three out ports can be user selectable to be IRIG, 10 MHz or PPS. Timing that is accurate in the tens of us. NTP that is in the tens of usec. PPS leading edge can be locked to the 10 MHz in 5 ns steps.

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.
