ABSTRACT:
Provided is A test apparatus that tests a device under test, including a power supply section that supplies power to a power supply terminal of the device under test; a power supply control section that controls the power supply section to output the power at a plurality of voltage levels; a current measuring section that measures, at each voltage level, a current value of a quiescent current of the device under test, the quiescent current being supplied to the power supply terminal of the device under test by the power supply section; and an analyzing section that analyzes whether a defect is present in the device under test by using at least three current values from among the current values measured by the current measuring section at the plurality of voltage levels.
