APPARATUS FOR TESTING PERFORMANCE OF DEGAUSSING COIL AND METHOD THEREOF

摘要

PURPOSE: An apparatus for testing a performance of a degaussing coil and a method thereof are provided, which performs a component characteristics inspection and an overall characteristics inspection of a degaussing which a PTC(Positive Temperature Coefficient) or an NTC(Negative Temperature Coefficient) has from a television where the degaussing coil is installed. CONSTITUTION: An electric field sensing part(31) senses an induced electromotive force generated from a degaussing coil. A signal processing part(33) receives the induced electromotive force sensed by the electric field sensing part and performs a processing to digitalize the induced electromotive force. An AD(Analog/Digital) converter part(35) converts an analog signal processed by the signal processing part into a digital signal. And a performance inspection part(37) inspects the performance of the degaussing coil by analyzing a pattern of the digital signal. The electric field sensing part includes a sensing coil using an inductive material. And the signal processing part includes an amplifier(33a) amplifying the induced electromotive force and a signal distribution part(33b) alternating a signal being output from the amplifier.
