Claim:
1. An apparatus for detecting a fault in a digitizer, comprising: a function generator for generating one or more test signals; a transmitting switch for transmitting the test signals generated by the function generator to a selective part or all of X- and Y-channels of a transmitting digitizer; a receiving digitizer arranged in a shape identical to that of the transmitting digitizer to be adjacent to the transmitting digitizer, the receiving digitizer receiving reception signals produced by the transmitting digitizer; a receiving switch for receiving resulting signals, generated by the receiving digitizer in response to the reception signals generated by the transmitting digitizer, from a selective part or all of X- and Y-channels of the receiving digitizer; a channel controller for controlling the transmitting switch and the receiving switch; a data collection unit for collecting the resulting signals transferred from the receiving switch; and an analysis unit for analyzing the resulting signals collected by the data collection unit; wherein the analysis unit comprises an impedance analysis unit and a distribution map analysis unit.
