AR133-20 Ultra High Stability Rubidium Frequency Standard

AccuBeat’s AR133-20 is a compact Rubidium Frequency Standard providing a 10 MHz output and with exceptionally ultra-high stability (ADEV) of less than 5E-12 @ 1 second. This compact unit measures only 1" x 3" x 3" and in addition to the high stability it also provides ultra-low phase noise, improved 1PPS accuracy and low g sensitivity.

 

As part of the AR133 family of products it also has all the other features of this Rubidium Frequency Standard such as AccuBeat’s 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.
