电视信号、声音信号和交互服务的有线网络 第101部分：仅加载数字频道的前向路径的系统性能

[中文适用范围]： 本部分 IEC 60728 适用于任何仅分发数字信道的有线电视网络（包括个人接收系统），这些网络的前向路径具有同轴电缆输出，主要用于在约 30 MHz 至 3000 MHz 频率范围内运行的电视和声音信号。 本标准规定了具有同轴电缆输出的有线电视网络运行特性的基本测量方法，以评估这些系统的性能及其性能限值。 [外文原描述]： IEC 60728-101:2016 is applicable to any cable network (including individual receiving systems) distributing only digital channels having in the forward path a coaxial cable output and primarily intended for television and sound signals operating between about 30 MHz and 3 000 MHz. This standard specifies the basic methods of measurement of the operational characteristics of a cable network having coaxial cable outputs in order to assess the performance of these systems and their performance limits.
