摘　　要：基于电视接收机本机振荡电路的本振功率辐射(泄露)对其他电视接收机产生的影响,论及其对有线电视系统输出口所连接的电视接收机的图像干扰,以及本振泄露干扰与有线电视系统输出口的关系,由此讨论了对抗此种干扰的输出口隔离度要求及电平要求等对抗手段和方法。Based on the influence to the other TV sets caused by the power radiation （leakage） from the oscillating circuit of television receiver, the article discusses its image interference to the television receiver linked on the output of cable system, and the relationship between the vibration leakage interference and the output of the cable system. Then the methods on the requirements of the output port isolation and level against such interferences are put forward.

关 键 词：本振泄漏 干扰 隔离度 对抗
