Crystal aging per year

WebJun 7, 1996 · This paper reports on the results of pre-aging of four different types of OCXO crystal units. It compares the aging behaviour for a passive aging at +80/spl deg/C over 28 days and 12 days at different drive levels and the active aging in the following 34 days with the crystals continuously operating in oscillators. For the aging rates good correlation … WebFigure 2 Measured ageing curve with fit over one year The other 10% are very stable OCXOs with SC cut crystals, where other effects which are stronger than aging (like temperature stability, influence of adjacent oscillators, supply voltage variations, injection locking etc.) influence the ageing measurement. Thus the fitting
