  • Method and apparatus for landing adjustment jig calibration check
    Patent number: 6356301
    Abstract: A method and an apparatus that verify the correct operation and calibration of a wobbling coil CRT monitor landing adjustment jig. The video test signal and the wobbling coil signal are disconnected from the CRT under test. The invention receives the video test signal and the wobbling coil signal and generates a modulated video test signal by modulating the video test signal with the wobbling coil signal. The modulated video test signal simulates a correctly adjusted CRT or a CRT with a known amount of misadjustment regardless of the actual state of adjustment of the CRT under test.
