10 Channel Rubidium Reference Featuring Low Phase Noise NR2310-R/O

10 Channel Low Phase Noise Rubidium Frequency Reference

NR2310-RO

The phase noise for a standard Rubidium source is not acceptable for some applications. Our low noise Rubidium frequency reference incorporates a low noise OCXO that is locked to the Rubidium source. This combination gives you the best of two technologies – the stability of Rubidium and the low noise of an OCXO. This single rack unit chassis, having ten channels, frequently meets the needs of complex systems and often eliminates the need for a distribution amplifier.

  • Temperature stability <3E-10.
  • Harmonics <25 dBc Output amplitude 6.0 dBm.
  • Phase Noise (dBc/Hz).

10Hz     -125
100Hz   -140
1K         -145
10K       -150

  • Excellent holdover stability <3E-10/month.
  • Outputs are fault protected and monitored continuously.
  • Built-in test circuitry throughout the design.
  • Power supplies, signal present are monitored.
  • Available with 10 MHz square CMOS outputs.

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.
