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 10 MHz Frequency Reference Lock-In Amplifier-NA2306L

Six Channel Ultra Low Phase Noise 10MHz Lock-In Amplifier

Lock In Amplifier Restores Phase Noise and Maintains Synchronization


Ultra-low phase noise six channel lock-in amplifier can restore a marginal reference to low phase noise state without giving up timing synchronization.  To minimize vibration induced phase noise artifacts from fans and other sources, the OCXO is vibration-isolated. The unit can also be ordered with a GNSS-locked reference that is either OCXO or Rubidium based.  Front panel display and Ethernet Port allows remote status reporting.

  • OCXO holdover.
  • OCXO stability 5 ppb/day – 50 ppb/ year.
  • Frequency change from lock state < 10 ppb.
  • Auto-Calibration continually preserves OCXO compensation coefficients.
  • Outputs are transient and fault  protected.
  • Low phase noise  -160dBc/Hz @ 1 kHz.
  • Front panel LCD status display.
  • Ethernet connectivity.
  • Available from 10 to 50 MHz
  • AC/DC power capability.

    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.
