AR61 Military, Low Temperature, Radiation Hardened, Rubidium Frequency Standard

AR61A-08 Image

Product Description

AR61-08 is a very high performance Rubidium Frequency Standard, designed to operate reliably in extremely demanding applications and harsh environments. It is designed to perform over a very wide temperature range while providing high stability, even under severe vibration and with a very fast warm-up time, even at extreme temperatures (-54°C).

 

AR61-08 meets or exceeds the most severe military requirements making this ruggedized unit especially useful in airborne applications as well as mobile ground operation. The AR61-08 also includes a microprocessor, which optimizes its performance in relation to external disturbances. It has a unique holdover mode, which keeps the internal OCXO running with the last memorized frequency when lock is lost. In addition, a built in synthesizer allows a very fine digital frequency control over a wide range. The AR61-08 was designed for the United States Air Force and is integrated into several different projects and applications.
