标准摘要
[中文适用范围]： IEC 60728的本部分适用于仅承载数字调制电视信号、声音信号和交互式服务信号的有线网络的非线性测量方法。这些方法考虑了数字调制信号的特定信号形式和行为，其不同于主要由离散载波信号的存在所代表的模拟广播信号。 [外文原描述]： IEC 60728-3-1:2012 is applicable to the methods of non-linearity measurement for cable networks which carry only digitally modulated television signals, sound signals and signals for interactive services. These methods take into account the specific signal form and behaviour of digitally modulated signals which differ from the analogue broadcast signals represented mainly by the existence of discrete carrier signals.
英文名称Cable networks for television signals, sound signals and interactive services - Part 3-1: Active wideband equipment for cable networks - Methods of measurement of non-linearity for full digital channel load with DVB-C signals
