Five Channel 10 MHz OCXO Reference Locked to a PTP time server NR8002

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

Reference uses your PTP time server to discipline an OCXO. Eliiminates the need for a separate antenna or long coaxial runs to another reference. PTP/NTP client network-based precision frequency reference. Local network synchronization eliminates coax cabling complexity.User selectable 5 channel timing outputs with options for 10MHz, PPS, or IRIG signals. See the NS8001 as a PTP source.

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.
