High Precision Oscillators (OCXO / Twin-OCXO / Twin-DCXO)

Twin-OCXO : Twin-Oven Controlled Crystal Oscillator

High precision detection of the oven temperature is carried out with a twin crystal oscillator, and the new technology which performs temperature control by digital signal processing realizes the world highest performance as the class OCXO.
