Patent ID: 7265569

Claim:
A test apparatus for testing electronic devices, comprising: a control section for generating control signals based on a test program set in advance to test said electronic devices; a plurality of test modules comprising a test module for generating test signals to be supplied to said electronic devices on the basis of the control signals and a test module for generating source power to be supplied to said electronic devices; and a device interface having connectors, provided in correspondence to the plurality of test modules, for supplying the test signals or source power generated by said corresponding test modules to predetermined pins of said electronic devices; wherein said test module for generating source power to be supplied to said electronic devices outputs the source power only when it is connected with the connector set in advance among the plurality of connectors and does not output source power when it is not connected with said connector set in advance; and wherein each connector has two detecting pins provided at predetermined positions, the two detecting pins of said connector set in advance to be connected with said test module for generating the source power are short-circuited, the two detecting pins of the connectors other than said connector set in advance are not short-circuited, and said test module for generating the source power detects whether or not the two detecting pins of said connected connector are short-circuited and is allowed to supply the source power to said electronic device when the two detecting pins are short-circuited.
