摘要
A jig is used in place of a master Cathode Ray Tube (“CRT”) for calibrating a Stray Emissions Detection System (“SEDS”). Light Emitting Diodes (“LEDs”) are placed in the neck portion of a CRT, where the electron gun would normally be disposed, to form the test jig. These LEDs are activated during the calibration process to simulate the stray emissions that would be released through defects in a CRT. Because the number, pattern and light output of the LEDs can be controlled, and are not changed by the calibration procedure itself, the jig can be used to more reliably and effectively calibrate the SEDS for CRT manufacture.
