AI 中文摘要
本文描述并比较了两种测量电光调制器半波电压（Vpi）与驱动电信号射频频率关系的常用方法。必要时详细说明了所需校准程序，并从100MHz到40GHz进行了实验演示。最后根据应用和调制器特性给出了选择最合适方法的指导方针。
英文摘要
We describe and compare in this paper two common methods to measure the half-wave voltage (Vpi) of an electro-optical modulator versus RF frequency of the driving electronic signal. We detail the required calibration procedures when necessary and demonstrate the methods experimentally from 100MHz up to 40GHz. Guidelines are finally given to select the most appropriate method depending on the application and modulator characteristics.
