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.

10 Channel PPS Source - Rubidium Holdover Option NR2310D-PPS

10 Channel GNSS Locked 1PPS Source with OCXO or Rubidium Holdover

10 Channel 1PPS source with < 1 ns skewing


Ten transient and fault protected 1PPS outputs with < 1 ns of channel skewing (typical < 200 ps). 26 channel high-sensitivity, multi-GNSS receiver. supports TRAIM and various position modes, allowing it to output accurate and robust 1 PPS synchronized to UTC time. Supports GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multi-path Mitigation functions. Each channel is monitored and status displayed on the front panel. Built-in self-test drives a signal that can be tied into an alarm panel.  Rubidium holdover option holds PPS drift to less than 0.5 usec/hour ideal for GPS unstable environments.10MHz frequency reference output available to stabilize local oscillators.

    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.
