Full Description

Scope

This standard describes a method of measuring the amplitude levels of an SMPTE 170M-1994,1 NTSCcolor or monochrome television video signal. It is concerned with luminance measurements at variouspoints in transmission systems where the signals are at video frequencies. The methods described inthis standard are limited to the use of waveform monitors, software video processing for amplitudeassessment, or suitable oscilloscopes, and are primarily directed to specifying means of measuringtelevision signal levels for operating purposes.

Purpose

This standard provides a uniform method to measure the luminance portion of a video signal in thepossible presence of large chrominance portions. It also specifies a method of measuring video levels in a manner permitting ready correlation between measurements at different points of a system,regardless of the nominal voltages present.
