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.

100 MHz Self Calibrating GNSS GPS Disciplined Oscillator with 1PPS and NMEA-NR3620-100

100MHz Frequency Reference, Self-Calibrating, Single Channel GNSS GPS Disciplined, OCXO NR3620-100

GNSS Locked  100 MHz Frequency Reference

The NR3620-100 100 MHz frequency reference locks a low phase noise OCXO to the GNSS.  Controller continuously monitors the correction coefficients being applied to the OCXO to compensate for aging and temperature stability. The coefficients are stored in non-volatile memory and in the event of GPS loss, are used to maintain the accuracy of the crystal – GPS loss offset +- 10 ppb. NMEA and 1PPS outputs available.

  • Low phase noise OCXO.
  • GNSS GPS lock indicator and built-in self test.
  • Holdover stability of 7 ppb/day.
  • Self-calibration minimizes frequency transition during GNSS lock to < 10ppb.
  • Locked accuracy < 4E-11.

See demo video on YOUTUBE (NR3620)

 

  • Operates from DC power in three ranges +- (10 to 18, 18 to 36, 36 to 65) Vdc or an AC adapter.
  • 1PPS accuracy 15 ns 1 sigma.
  • Indicators and signals provide GNSS GPS lock and unit self-test status.
  • Available in kit form (includes reference, active antenna, 50′ cable, and power adapter).

GPS DO Kit available, wide input power range (-60 to +60 Vdc)

    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.
