PROBLEM TO BE SOLVED: To provide a semiconductor tester, comprising a terminator which is capable of terminating with a proper waveform quality and accurately measuring the timing of a DUT with output pins, even when they have low current drive powers. SOLUTION: The semiconductor tester has a terminator, provided in pin electronics which terminates an output signal from an IC pin of a device under test (DUT) with a specified termination resistance. It comprises a means for reducing the load current, flowing in the terminating resistance as specified according to the current drive power at the output end of the DUT.
