The theory of passive intermodulation generation on printed transmission lines has been proposed. The new model for a terminated section of the transmission line with distributed nonlinear resistance has been developed and verified against the

PCR 是由金属轴、导电泡沫橡胶层、电阻层、保护层构成，负责为 OPC 表面充电。当使用一到二个周期后，PCR 容易发生老化，造成表面电阻增加。对于生产厂家来说，检测 PCR 的表面电阻非常重要。因此，设计一个 PCR 电阻检测系统，用于批量检测 PCR 部件的优劣是非常必要的。 本 PCR 电阻检测系统实现的功能如下： 50V ~ 500V高压可调产生电路、电流取样电路及调理、矩阵按键实现、上位机通信及调试信息显示(PCR is composed of metal shaft, conduct
