The factors that affect the frequency response of a capacitive divider were studied carefully . a coaxial voltage capacitive divider with an umbrella probe and a low - voltage circuit was presented . experiments shown that the frequency response of our probe is better than others of such dividers 本文分析了影响电容分压器响应的因素,探讨了伞式探针的性能,设计了以伞式探针为基本结构的同轴电容分压器,提出了测量不同信号的两种i 。
