Me y log t ro OSA 3230 Cesium Clock The OSA 3230 as Metrological Reference Clock Source using the Digital Cesium technology Introduction For years, cesium beam frequency standards have been constantly improved so as to satisfy the increasingly stringent specification of time and frequency reference equipments. The availability of “easy to operate” instrument of reduced size and weight and of exceptional accuracy and stability provides the user with great flexibility in using cesium standards for meeting the stringent requirements of navigation, communication and timing systems. The Oscilloquartz’s 3230 Cesium Clock is an atomic frequency standard based on a hyperfine transition in the ground state of the cesium 133 atom. Highlights The Oscilloquartz’s 3230 Cesium Clock is specifically designed and produced with the latest technology in a very compact and reduced size. Taking into consideration its unique reduced volume, the Oscilloquartz’s 3230 offers a set of operation features and performance without comparison on the market.
