Excellent for Airborne applications

AR61A-08 is a very high performance Rubidium Frequency Standard, designed to operate reliably in demanding application and harsh environment. It performs over a very wide temperature range, provides high stability, even under sever vibration and very fast warm-up, even at -54°C. The unit meets or exceeds the most severe military requirements. This rugged unit is especially useful in airborne applications as well as mobile ground operation. The AR61A-08 also includes a microprocessor, which optimizes its performance vs. 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.
