There are many sources of distortion in a television picture --- the camera tube, camera control circuits, the transmitter, the receiver, and the kinescope all contribute d.istortions of various kinds. This paper is concerned with distortions from only one source, the kinescope and its associated deflection and focussing circuits, whether they be electrostatic or magnetic. The kinds of distortion from this source are discussed, and then the means of detecting and measuring them that have been used are described. The remainder, and majority, of the paper is devoted to the detailed description of a "Kinescope Quality Measuring Devicett and the problems encountered in building it. The Kinescope Quality Measuring Device is a convenient means of observing and measuring the distortions of a television picture contributed by the kinescope and its associated deflection and focussing circuits.
