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.

Portable 10 MHz GNSS GPS Stabilized Frequency Reference with OCXO or Rubidium Holdover Stability with in 0.5 ppb NR300

Portable 10 MHz OCXO or Rubidium based GNSS Disciplined Frequency Reference Holdover Stability < 0.5 ppb

NR300

The frequency reference that allows you to start out in a GNSS environment then bring the reference into a GNSSS denied environment and hold < 0.5 ppb for 4 hours. Once you return to a GNSS available environment the instrument will report the amount of drift that occurred in the denied environment. GNSS-locked 10 MHz OCXO based frequency reference locked to a 26 channel multi-satellite system receiver,  Unit produces 3- 10 MHz Sine, 1PPS, NMEA and a synthesized secondary channel that can range from 14 kHz to 10 MHz.   Auto-calibration maintains output stability in an intermittent GPS environment. Battery provides for in excess of four hours of use.  Event inputs record to 100 ns resolution. Rubidium PPS holdover < 5 usec/day

    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.
