ABSTRACT:
Provided is a test apparatus for testing a device under test, the test apparatus including: a pattern generating section that inputs a test pattern to the device under test; a judging section that receives an output signal of the device under test, and makes judgment concerning pass/fail of the device under test based on the output signal; an internal circuit that exchanges signals between the device under test and the pattern generating section or the judging section; a first transmission line that connects the internal circuit to the device under test; and a first switch that connects the first transmission line to a ground potential in not testing the device under test, and cuts off the first transmission line from the ground potential in testing of the device under test.
