本标准描述了电视接收机图像和声音部分性能特征的测量程序。如果规定了具体的测试条件，则这些条件适用于根据美国联邦通信委员会的规范设计用于接收传输的家庭广播接收器。1如果其他条件适用，必须进行适当的修改。重点放在整个接收机性能上。通常不考虑各个阶段的增益和带宽等内部特征。

This standard describes procedures for measurement of the performance characteristics of the picture and sound sections of television receivers. Where specific test conditions are stated, these apply to home broadcast receivers designed to receive transmissions in accordance with the specifications of the United States Federal Communications Commission.1 Where other conditions apply, appropriate modifications must be made. Emphasis is placed on over-all receiver performance. Internal characteristics such as the gains and bandwidths of individual stages are not generally considered.
