标准摘要
[中文适用范围]： 本部分 IEC 60728 适用于任何有线电视网络（包括个体接收系统），其正向路径具有同轴电缆输出，主要用于约30 MHz至3000 MHz之间的电视和声音信号。 本部分 IEC 60728 规定了有线电视网络同轴电缆输出的操作特性的基本测量方法，以评估这些系统的性能及其性能限制。 [外文原描述]： IEC 60728-1:2014 is applicable to any cable network (including individual receiving systems) 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. It specifies the basic methods of measurement of the operational characteristics of cable network having coaxial cable outputs in order to assess the performance of these systems and their performance limits. This fifth edition cancels and replaces the fourth edition published in 2007 and constitutes a technical revision. It includes the following changes: - redrafting of measurement procedure and updating of performance requirements to include DVB-T2 signals; - reference to IEC 60728-1-1 for home networks; - reference to IEC 60728-1-2 for performance requirements at system outlet in operation.
英文名称Cable networks for television signals, sound signals and interactive services - Part 1: System performance of forward paths
