Operational Tests for Color Television

The advent of compatible color television has brought with it the need for several new types of test instruments to facilitate the adjustment of the specialized circuits required for generating, transmitting and receiving color television signals. This paper consists of descriptions of a selected group of test instruments which have been found particularly useful for routine operational tests in broadcasting plants and receiver service shops. Test generators which provide noise-free, artificial color signals are described, and techniques for using such signals for the adjustment of critical circuits in broadcast equipment and in home receivers are outlined briefly.
