摘　要:介紹了不使用頻差倍增器測(cè)量數(shù)字通信儀器內(nèi)部高穩(wěn)時(shí)基日老化率的測(cè)試方法——頻率合成器倍頻法和示波器同步法，并給出了日老化率指標(biāo)的計(jì)算公式。測(cè)試結(jié)果與使用頻差倍增器測(cè)試結(jié)果比較表明，三者的測(cè)量結(jié)果相當(dāng)一致，為沒(méi)有頻差倍增器的實(shí)驗(yàn)室開(kāi)展高穩(wěn)時(shí)基日老化率的測(cè)試提供了新的思路。同時(shí)，此測(cè)試方法也可用于高穩(wěn)時(shí)基的頻率測(cè)量。[著者文摘]


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]
