Patent attributes
A test apparatus for a device under test (DUT) that includes a signal output device that outputs a signal according to a test signal and a detecting section that detects a signal output from the DUT that outputs a detection result. The signal output device includes an output port, a high-voltage side switching circuit between a first terminal and a second terminal, a low-voltage side switching circuit between a first terminal and a second terminal, and a control section that outputs the first and second control signals. Each of the high-voltage and the low-voltage side switching circuits include a plurality of switching devices serially connected between the first and second terminals. The plurality of switching devices are opened substantially in synchronization with each other, such that a voltage inputted to the first terminal is outputted from the second terminal by short-circuiting between the first and second terminals.
