发明名称 Test apparatus and measurement apparatus for measuring an electric current consumed by a device under test
摘要 There is provided a test apparatus for testing a device under test, which includes a voltage supplying section that supplies a voltage to the device under test through a wire, a first capacitor that is arranged between the wire and a common potential in series, a current detecting section that detects a current flowing through the wire at a location closer to the device under test than the first capacitor is, an integrating section that outputs an integration value obtained by integrating a difference between the current detected by the current detecting section and a predetermined reference current, and a judging section that judges whether the device under test is a pass or a failure based on the integration value.
