Cesium Clocks

Primary Refrence Source using Cesium

Meeting stringent specifications requires the implementation of a Primary Frequency Reference that generates signals with an accuracy better than 1E-12, at all times, and very high frequency stability (typ sy(t) # 7x10-13 t-1/2 in the time domain).  Cesium units from Oscilloquartz meet the most stringent requirements demanded by commercial, military and space applications. 

OSA 3230B Cesium Clock

The Oscilloquartz’s OSA 3230B Cesium Clock is specifically designed and produced with the latest technology to serve complex applications where an extremely accurate reference signal is needed in a minimum size. Read more »

OSA 3235B Cesium Clock

Taking into consideration its unique reduced volume, the OSA 3235B offers a set of operation features and performance without comparison on the market. Available with a long life cesium tube, OSA 3235B will meet the requirements where performances are needed over a long period of time. Read more »


Atomic clocks standards are needed to generate highly accurate frequencies. These are typically used as Primary Reference in telecommunications networks, navigations systems, ground stations (LORAN C, GPS, GLONASS, GALILEO, etc…), long wave and medium wave broadcasting stations. Read more »
