TEST APPARATUS, TEST METHOD, WAVEFORM GENERATOR AND WAVEFORM GENERATING METHOD

摘要

A test apparatus for testing a device under test including a receiving circuit for receiving signals transmitted through a communication cable is provided. The test apparatus 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 filer 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.
