Description

The AR133A-03 is a ruggedized version of Rubidium Frequency Standard model AR133A which is designed for airborne applicaꢀons. A

vibraꢀon isolator included in the AR133A-03 enables the unit to maintain high frequency stability and accuracy in vibraꢀon environments

such as airborne plaꢂorms.

The unit features very fast warm-up and could be disciplined to an external 1PPS from GPS or other sources. It is one of the smallest, high

performance disciplined rubidium frequency standards available today. The AR133A is 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.

Performance SpeciﬁcaƟons

All speciﬁcaꢀons deﬁned at 25°C, quiescent condiꢀons, ambient sea level and nominal supply voltage unless otherwise speciﬁed.
