NR8002 5-Channel 10 MHz OCXO Reference Locked to PTP/NTP Time Server

Five-Channel PTP-Locked, 10 MHz OCXO Reference (NR8002)

This reference locks to your NTP/PTP time server over existing CAT5 networks for precision timing, eliminating the need for a separate antenna drop or long coaxial runs to another reference. Each of the 5 channels is independently selectable for 10MHz, PPS, or IRIG signals. See the NS8000 and the NS8001 as a NTP/PTP source.

• supports Unicast, Multicastm or Broadcast
• benchtop or rackmount with available kit
• five channels independently selectable to be 10 MHz, PPS or IRIG-B
• auto-calibration preserves GNSS-derived coefficients for OCXO holdover stability
• OCXO holdover stability: 5 ppb/day, 50 ppb/year; locked accuracy <1E-11
• low phase noise: −145 dBc/Hz @ 1 kHz offset
• front-panel LCD with status LEDs for channel, antenna, oven, and system alerts
• ethernet connectivity with NTP/PTP
• outputs are transient and fault protected; low-jitter PPS with PL-option
• supports GPS, GLONASS, SBAS, and QZSS constellations for faster lock and reliability
• AC/DC power capability; rackmount chassis; BNC output connectors

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.
