The Simple Approaches for Measuring the OXCO Aging Rate of Digital Communication Testing InstrumentZHAN Zhi-qiang, LU Fu-min Shanghai Institute of Measurement and Testing Technology, Shanghai 200233 Abstract:The new Approaches are presented for measuring aging rate of internal Oven Controlled Crystal Oscillator （OCXO） in digital communication measurement instnunents without Frequency Difference Multiplicator, and the aging rate calculating formula is given. The comparison results of the measurement data with the Frequency Difference Multiplicator measurement data demonstrate great agreement with each other. The new Approaches for measuring the aging rate in which the laboratory without Frequency Difference Multiplicator are given, and the Approaches also can be used for measuring the frequency accuracy of OCXO.[著者文摘]
