基于HP3048A系统的晶体振荡器相位噪声的快速测量方法

Approach of Oscillator Phase Noise Measurement Based on HP3048A Phase Noise Measurement System

介绍了一种基于HP3048A相位噪声测量系统的相位噪声的拓展测量方法(即用USB接口卡取代HPIB接口卡,用与待测信号源具有相同中心频率的VCO取代HP8662),讨论了该拓展方法在射频信号源相位噪声测量中的应用,并给出了测量系统噪声本底的方法以及射频晶振的典型测量结果。

An expanded approach of the phase noise measurement based on the HP3048A phase noise measurement system is described. That is replacing the HP-IB card with USB interface card,and using VCO which has the same center frequency with the source to be tested to replace HP8662. The application of this expanded system in the RF source phase noise measurement and the typical measurement results are presented.
