Patent ID: 7277303

Claim:
A test apparatus for testing an electronic device, comprising: a deciding section coupled to the electronic device, said deciding section determining whether the device has abnormalities; and a power source apparatus coupled to the electronic device, said power source apparatus including a master circuit and at least one slave circuit provided in parallel with said master circuit and outputting an electric current composed by adding an electric current output from said master circuit to an electric current output from said slave circuit as a power-supply current, said master circuit comprising: a main circuit side output section operable to output an electric current depending on a given voltage; a main circuit side reference power source operable to generate a reference voltage corresponding to a power-supply voltage that the power source apparatus is to output; a main circuit side control section operable to supply the voltage corresponding to the reference voltage to said main circuit side output section in order to control the current output from said main circuit side output section; and a connection section operable to detect the current output from said main circuit side output section and to supply a voltage into which the current has been converted to said slave circuit, and said slave circuit comprising: a sub-circuit side output section operable to receive a voltage based on the electric current output from said main circuit side output section and to output an electric current depending on the voltage, said sub-circuit side output section having the same characteristic as that of said main circuit side output section.
