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 10 MHz Rubidium Frequency Reference NR2310D-R

10 Channel, 10 MHz Rubidium Frequency Reference with Display and Networking – NR2310D-R

High Stability 10 channel, 10 MHz Rubidium Frequency Reference

NR2310D-R

 

A low cost reference featuring the stability of Rubidium (< 1 ppb/year). In many applications, an OCXO does not have the stability required and GNSS GPS locking is not an option. This reference offers excellent stability where cost is a major driver and the higher phase noise of Rubidium is acceptable. If low phase is also required see our NR2310D-RO that adds a low phase noise OCXO to improve phase noise. The ten channel configuration yields a better phase noise and skewing than a reference and a separate distribution amplifier. Skewing for the ten channels is less than 5 ns. This single rack unit chassis, having ten channels, frequently meets the needs of complex systems and often eliminates the need for a distribution amplifier.

    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.
