10 Channel Rubidium Reference NR2310D-R

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

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 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.

  • Temperature stability <3E-10.

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.
