Several of the characteristics of a cathode-ray tube which determine its usefulness as a Kinescope for television reception are outlined. Various means for studying these characteristics are discussed. A system is outlined for studying Kinescope resolution by breaking the picture into alternate black-and-white picture elements arranged in checkerboard fashion. A practical application of this system is described for a television system using a picture frame of approximately 340 lines repeated thirty times per second. The deflection and grid-signal frequencies that are involved are discussed. The problem of synchronizing these frequencies is covered and the circuits developed for this purpose are described. Some of the results obtained with these circuits are shown.
