Accurate Time & Frequency Ruggedized System
The AR133 series are AccuBeat's Standard and high performance atomic clocks, where the accuracy and stability are derived from a quantum transition that occurs in a free rubidium atom. The units utilizes a unique advanced technology, which allows a high-performance component with several options for adjusting the clocks to the different customer requirements. AR133 series are one of the best stable, robustness and accurate atomic clocks in the world.
Comprised of a unique DFLL (Digital Frequency Lock Loop) where a high performance crystal oscillator is locked to the rubidium atomic line using an embedded microprocessor and a special patented algorithm. The algorithm optimizes the performance vs. external disturbances, improves temperature stability, and enables very fine digital frequency control.
