Quantitative "Black Box" Measurements for TV Receivers

The ultimate function of a TV receiver is to translate an esoteric RF signal into a two dimensional illuminated picture and its associated audio. Although it is quite common to measure the ultimate audio, especially frequency response, in an anechoic chamber or reverberant chamber, measurement techniques for the ultimate output of video, the light from the picture tube, are not quite as common. They are, however, useful and are the ultimate in non-disruptive testing.
