Tentative Methods of Measurement of Color Television Receiver Performance

The Measurement of performance data is an essential factor in the successful design and manufacture of commercial television receivers. Such data establish a quantitative basis for the evaluation of design improvements and also for the comparison of a product with competitive merchandise. Since the usefulness of performance data lies largely in their function as a basis of comparison, it is necessary that the type of measurements and the techniques employed be standardized. The standards established by the IRE covering methods of measurement of monochrome receivers have been adopted in most part by the television industry. However, the advent of color television has resulted in the introduction of receiver functions for which there are presently no standardized measurement procedures. The purpose of this report is to describe methods employed in the Hazeltine laboratories for the measurement of color television receivers and to serve as a reference for the industry in setting up test procedures.
