Abstract
The method of tuning a flyback transformer in a cathode ray tube control system, for minimum ringing, which comprises the steps of adjusting the lateral position of the center plane of the high voltage or secondary coil, with respect to the center plane of the low voltage or primary coil, placing an electric sensor in the vicinity of the high voltage coil to pick up a signal, which is a function of the current in the high voltage coil, and applying that signal to an oscilloscope, and noting the change in amplitude of the ringing component of the signal as a function of the lateral displacement between the two coils. By this means, the selected relative position of the two coils which provides a minimum amplitude of ringing is found and the coils are locked in that relative position to each other and to the magnetic core.
