ABSTRACT:
To test a cathode ray tube or an apparatus comprising a cathode ray tube, a part of the electron gun is heated by means of high-frequency electromagnetic radiation. By virtue thereof, the warm-up period, that is the time which, after turning on the cathode ray tube, must elapse before the testing operation can be carried out, can be reduced, for example, from approximately 30 minutes to approximately 2 minutes.
