The Aperture Grille AG of a Diamondtron CRT is fixed on an AG frame with some tension in a specific direction and supported on a panel by four springs welded to the edge of the AG frame. When the panel vibrates, the vibration is transmitted to the AG frame and the AG. This causes a disturbance in the image on the panel. It is therefore necessary to restrain AG vibration in order to make the CRT high‐resolution. This paper describes the vibration measurement system developed to analyze the vibration of the AG and its frame, the vibration model based on experimental results, and the method utilized to restrain the AG vibration.
