Patent ID: 7913002

Claim:
A test apparatus for testing an electronic device, comprising: a bus switch unit comprising a plurality of output ports, said bus switch unit switching said output ports to select which of said output ports an input signal is output from; a control unit that inputs a plurality of control signals, according to a test program for testing said electronic device, to said bus switch unit and controls which of said output ports each of said control signals is output from; a plurality of slots provided corresponding to said plurality of output ports, wherein a test module, which generates an input signal to be input to said electronic device based on said control signal and receives an output signal output by said electronic device, is mounted on one of said plurality of slots; and a device interface comprising: a plurality of connectors to be coupled to said electronic device, said device interface switching said connectors to select which of said connectors is coupled to said one of said plurality of slots; and a diagnosis decoder that sequentially supplies a diagnosis signal from one of said connectors to said test module to the output port of said bus switch unit to which said one of said plurality of slots corresponds, wherein said control unit obtains information representing from which of said connectors said test module receives said diagnosis signal supplied by said diagnosis decoder, and detects which of said connectors is coupled to each of said output ports by comparing a connector identification number corresponding to said information with a connector identification number stored in a configuration file indicating module identification information identifying said test module to be mounted on said one of said plurality of slots.
