All commercial rubidium frequency standards operate by disciplining a crystal oscillator to the hyperfine transition at 6.834,682,612 GHz in rubidium.
frequency standard, by far the most widely deployed type of atomic clock. Since the early 1960’s, rubidium frequency stand-ards (RFS) have offered an attractive combination of practicality and performance that spans a range of applications from low-cost commercial devs B. for telecommunications timing, rugged-ized tactical units for military use, and high stability, high relia-bility
The RFS10E is a 10 MHz rubidium frequency standard with many options as described below. An optional input allows the RFS10E to be locked to a 1 pps signal such as GPS, or to other frequencies such as 5 or 10 MHz. Also the 1 pps output derived from the rubidium will align itself in time to the 1 pps input to within 50 ns.
The resonant frequency of rubidium clocks 6834.6875MHz to 1 / 136 in 50.255055MHz. The DDS to change settings that can be configured with any frequency. Rb87 the resonant frequency of 6834.6826128MHz According to the literature of the PRS-10 in the SRS and that this frequency is FEI's EFRATOM and that's why is 6834.6875MHz.
types of equipment also require better frequency-stability and accuracy than their own internal, local oscillator can provide. Calibration oratories as well as electronics manufacturers can use the 8040C for frequency refer-ences, calibration, and frequency-measurement equipment refer-ences. For many applications, a rubidium frequency standard provides a useful compromise between cost
The AR133A is AccuBeat’s new generation multifunctional Rubidium Frequency Standard. It is one of the smallest atomic standards availe today, where the accuracy and stability are derived from a quantum transitionthat occurs in a free rubidium atom.
The Microsemi 8040C and 8040CLN provide a stable and accurate frequency reference with multiple output signal formats in an easy to install 1U rack mountable chassis. The 8040C/8040CLN delivers atomic clock performance, improved frequency, long-term stability, and configurable RF outputs, built-in GPS disciplining and a RS-232 interface for command and control in the field.
The RFS10F is a 10 MHz rubidium frequency standard with many options as described below. An optional input allows the RFS10F to be locked to a 1 pps signal such as GPS, or to other frequencies such as 5 or 10 MHz. Also the 1 pps output derived from the rubidium will align itself in time to the 1 pps input to within 150 ns.

Important Types of Frequency Standards. Cesium Standard (Primary standard) Rubidium Standard (Secondary standard) Crystal Standards (Tertiary standard, and below) Cesium (caesium) Standard: The cesium standard is the primary standard of time/frequency. It is the standard maintained by over 250+ atomic stations around the world for keeping the UTC. The commercially availe primary standards
Rubidium is also used as an ingredient in special types of , in the production of superoxide by burning in oxygen, in the study of potassium ion channels in biology, and as the vapor in atomic magnetometers. In particular, 87 Rb is used with other alkali metals in the development of spin-exchange relaxation-free (SERF) magnetometers.
