Abstract: A test apparatus includes: test modules that communicate with the device under test to test the device under test; additional modules connected between the device under test and the test modules, each additional module performing a communication with the device under test, the communication being at least one of a communication performed at a higher speed and a communication performed with a lower latency, in comparison with a communication performed by the test modules; a test head having a plurality of connectors that connect the test modules and the additional modules, respectively, the test modules and the additional modules are mounted on the test head; a performance board placed on the test head that connects between at least a part of terminals of the plurality of connectors and the device under test. The test modules are connected to the additional modules without through the performance board.

Abstract: A test apparatus, which is for testing a device under test including a receiving circuit for receiving signals transmitted through a communication cable, includes: a waveform generating section for outputting waveform data to define a waveform to be provided to an input terminal of a receiving circuit; a digital filter having the filter characteristic substantially reverse to the attenuation characteristic of the communication cable, for outputting amplified waveform data obtained by amplifying the waveform data; a DA converter for converting the amplified waveform data to an analog waveform; and a low-pass filter having the attenuation characteristic substantially same as that of the communication cable, for attenuating the analog waveform and providing the same to the receiving circuit.
