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.

Low Phase Noise Dual Channel 10 MHz Frequency Reference 50 and 100 MHz Options

NR2110-O

The NR2110 is a 10 MHz precision OCXO frequency reference. Excellent aging is achieved through the use of an intrinsically low jitter overtone SC cut crystal placed in a thermostatically controlled oven. Low phase noise is achieved by the inherent characteristics of the crystal and appropriate design techniques. Dual outputs are transient and fault protected. Equipment status is reported thru front panel indicators as well as with the RS232 port.

Dual channel,10 MHz frequency reference.
