To provide a semiconductor test apparatus which is capable of adjusting skew efficiently with sufficient operational convenience. The semiconductor test apparatus tests a semiconductor device based on a signal obtained by applying a test signal to the semiconductor device, and includes a driver pin block. The driver pin block is provided with: a plurality of drivers which generate the test signal; at least one adjustment comparator which is connected to output terminals of the drivers and which is used for adjusting timings of the drivers; and a reference signal input terminal to which a reference signal for adjusting a timing of the adjustment comparator is input.

A driver circuit integrated with a load current output circuit has a function as a driver for applying a predetermined test waveform to a device under test (DUT), and a function as a load current output for reproducing an actual use situation by receiving the load current to the DUT to judge a response waveform by receiving the response waveform from the DUT. Both functions are made up on a common circuit, operate as the driver circuit when applying the test waveform, and operate as the load current output circuit when judging the response waveform.
