Frequency References

Frequency References

Novus offers a diverse set of frequency reference products. From our low cost TCXO frequency references to our Rubidium frequency references to our high-performance GPS disciplined references (GPS DO) -Novus frequency references offer low phase noise, accuracy and reliability. From one to twenty channels, modular, rackmount, portable or micro-packaged- Novus offers a form factor to meet your frequency reference needs. Available features include redundant power, SNMP, self-test, ultra-low phase noise, dual-Time base, real-time Allan Deviation, and synthesized frequency references.

For use cases that demand greater precision, we have GPS disciplined oscillators that will provide single satellite tracking capabilities that are GLONASS compatible and therefore supported by GPS, GLONASS, QZSS, and SBSS networks.

If you’re unsure which frequency reference you require, don’t hesitate to reach out. We are also able to manufacture custom units for unique applications.

Dual Channel GNSS Locked OCXO 10 MHz Frequency Reference with Networking/Dual-Time Base Option

NR2110D-O/G with NTP

Dual channel GNSS-locked OCXO, 10 MHz frequency reference with PPS and Ethernet connectivity. The unit features auto-calibration so that the most recent coefficients to compensate the OCXO for drift due to aging and/or temperature are stored and applied to the OCXO during GPS loss-of-lock conditions. High performance 26 channel GNSS receiver that supports GPS, GLONASS, SBAS, QZSS. By being able to receive data from multiple satellite constellations, lower lock time is achieved. Front panel display and Ethernet port allows remote status reporting. Dual time base option adds a completely independent GNSS receiver and gapless counter to monitor the 10 MHz reference- warns of a reference out of tolerance condition.

  • OCXO holdover.
  • OCXO holdover stability 5 ppb/day – 50 ppb/ year.
  • Auto-Calibration continually preserves OCXO GNSS derived compensation coefficients.
  • Outputs are transient and fault protected.
  • Fault status drives a front panel LED..
  • Low phase noise  -145dBc/Hz @ 1 kHz.
  • Locked accuracy <1E-11.
  • Front panel status indicators for channel faults, antenna fault or open, oven and unit alert.
  • Front panel LCD status display.
  • Dual-time base option continually monitors the primary reference.
  • Ethernet connectivity.
  • AC/DC power capability.
  • HS3 Stability option provides real-time Allan Deviation
  • NTP time server.
  • PL-option locks the PPS to the 10 MHz sine in 5 ns steps and reduces pulse to pulse jitter
  • Available with either BNC or SMA output connectors
  • Kit available with active antenna
