Rubidium Frequency Standards

Rubidium Frequency Standards

Rubidium frequency standards are a low-drift alternative to an OCXO or TCXO with stability of < 1 ppb/year. As high-precision oscillators, Rubidium frequency standards are especially useful for measurement, testing, and many telecommunication applications. To further enhance a Rubidium based frequency reference, Novus offers Rubidium frequency references with an embedded low phase noise OCXO to meet system frequency reference phase noise requirements. A Rubidium reference is alternative source if a GPS disciplined oscillator is not an option.

Affording excellent stability, Rubidium frequency standards are a next best choice when operating in a GPS denied environment. That being said, adding a GPS-locking system will improve the 1ppb/year drift by approximately three orders of magnitude. For typical telecommunication infrastructure, GPS, or other types of applications, Rubidium standards offer excellent holdover performance.

Dual Channel Low Noise Rubidium 10 MHz Frequency Reference NR2110D-R-O

Dual Channel, Low Noise Rubidium 10 MHz Frequency Reference – NR2110D-R-O

NR2110D-R-O

High Stability Low Noise Rubidium Frequency Reference

For many applications, the phase noise of a 10MHz Rubidium reference is not acceptable. The NR2110D-R-O incorporates a low noise OCXO that is disciplined to the Rubidium reference.   Channels are continuously monitored and displayed locally and accessible via RS232 or Ethernet.

  • Two transient and fault protected channels with local indicators on the front and rear panel.
  • Option-operates from AC or DC power sources..
  • Monitor and set alert limits on each output.
  • aging less than 5E-11/month (unlocked)
  • temperature stability <5E-10 0 to 50C (unlocked)
  • Warm-up time , 12 min
  •  BNC output connectors
  • Networking with SNMP
  • Available with either SMA or BNC output connectors
