10 MHz Frequency References – OCXO, TCXO and Rubidium Based. GNSS-Locking Provides Long-Term Stability

Novus offers a range of GNSS GPS disciplined oscillators and related reference products. While our most  popular frequency reference is 10MHz, many of our products are available at 50 and 100 MHz. Unique frequencies are available as well. Novus references can be OCXO , TCXO or Rubidium based. GNSS-locking enhances long-term stability.  Stability options are available that incorporate vibration and thermal isolation. Our reference products are available in 19 inch rack mount and modular, chassis.  Our miniature PicoPod series fits almost anywhere.  Novus reference distribution amplifiers offer minimal phase noise contribution and skewing.  Novus PPS sources can be synchronized to a 10 MHz reference to provide a complete timing solution.  Our PPS sources can be directly from a GPS PPS source or processed to improve jitter and statistical accuracy. For GNSS denied environments,  Novus offers a range synthesized 1PPS sources.   Our PPS distribution amplifiers offer sub 1 nsec skewing and transient and fault protection. For enhanced control and monitoring, SNMP and local control are available as options. Portable reference products offer excellent holdover stability to provide accuracy in GNSS denied environments.

Six Channel GNSS GPS Locked, 10 MHz, Ultra-Low Phase Noise with Networking NR2306-O/G

Six Channel Ultra-Low Phase Noise, GNSS GPS Disciplined, 10 MHz or 50 MHz Frequency Reference

Six Channel Frequency Reference Locks to GNSS or External 10 MHz or 1PPS



An ultra-low phase noise six channel reference that can be GNSS GPS-locked, locked to an external 10 MHz or an external 1PPS. Available as a 10 MHz or 50 MHz reference.  Available as an OCXO or Rubidium based reference. A low noise OCXO is vibration- isolated from the assembly to minimize mechanically induced phase noise.  Synthesized 1PPS features sub 1 ns jitter. All channels are fault and transient protected. Internal monitoring allows local channel amplitude via an LCD display or remote monitoring via an RS232 port or optional SNMP. Ultra-low phase noise, GNSS GPS locked 6 channel reference with SNMP, local display and NTP time server option.

  • GNSS GPS, external 10 MHz, external 1PPS or locking options.
  • OCXO stability 5 ppb/day – 50 ppb/ year (unlocked).
  • Rubidium option with holdover capability of < 1 ppb/year.
  • Auto-Calibration continually preserves OCXO compensation coefficients.
  • Outputs are transient and fault  protected.
  • Low phase noise  -160dBc/Hz @ 1 kHz.
  • Locked accuracy ~E-12.
  • Front panel LCD status display.
  • Optional Ethernet connectivity.
  • AC/DC power capability.
  • SNMP.
  • NTP time server option.

    GPS DO Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
