本标准描述了电视视频信号线性波形失真的测量方法，即由电视设备和设施的振幅无关（线性）传输特性引起的失真。1本标准主要适用于常规操作和维护试验，需要快速解释试验结果。这里描述的技术也可能适用于实验室测量、性能测量证明和详细的维护程序。

This standard describes methods for measuring the linear waveform distortions of TV video signals, that is, distortions which are caused by amplitude-independent (linear) transmission characteristics of television equipment and facilities.1 The primary application of this standard is for routine operational and maintenance tests, where rapid interpretation of test results is desirable. The techniques described here may also be applicable to laboratory measurements, proof-of-performance measurements, and detailed maintenance procedures.
