The AR133 product family is AccuBeat’s new generation of multifunctional rubidium frequency standards. The AR133 product family includes several different sub-versions and is one of the smallest atomic standards available today, with accuracy and stability derived from a quantum transition that occurs in a free rubidium atom. The device utilizes a unique advanced technology that allows the size of the device to be reduced without compromising performance.

The AR133 consists of a unique DFLL (Digital Frequency Lock Loop) that couples a high performance crystal oscillator to the rubidium atomic line using an embedded microprocessor and a special patented algorithm. The algorithm optimizes performance against external noise, improves temperature stability, and provides very fine digital frequency control.
