Time & Frequency Systems
Oscilloquartz Time & Frequency products and systems provide highly reliable and unsurpassed reference signals performances for satellite tracking stations, secure communications systems, metrology and other applications.
Often based on functions or products available from our regular production line or issued from generic products adapted to suit the application requirement. The choice of the Frequency reference sources is invariably defined in function of the application and the technical requirement. It includes Hydrogen Maser, Primary Cesium Standard, GPS Receiver as stand alone reference or a combination of them.
When coupled with our BVA state-of-the-art oscillator, short term performances and phase noise characteristics are raised to the highest level attained with commercial products. The BVA is ideally suited for this purpose as it offers excellent stability characteristics and is less sensitive to temperature changes than most oscillators.
This combination provides signals of excellent stability performance as well as high spectral purity, necessary for a wide range of applications. When locked to an Hydrogen Maser, Cesium Standard or GPS/GLONASS Receiver, the BVA oscillator provides the optimum long term performances of the frequency reference combined with the excellent short terms characteristics of the BVA.
