ABSTRACT:
A testing apparatus for testing a device under test, includes a power source for generating a current, a coaxial cable unit for supplying the current to the device under test, a detecting unit for detecting a voltage applied to the device under test when the current is supplied to the device under test and a judging unit for judging quality of the device under test based on the detected voltage, wherein the coaxial cable unit includes a first coaxial cable including a first internal conductor and a first external conductor, and a second coaxial cable including a second internal conductor and a second external conductor, wherein the first internal conductor and the second external conductor conduct a current from the power source towards the device under test, and the first external conductor and the second internal conductor conduct a current from the device under test towards the power source.
