Abstract
An amplitude expected value data generator generates amplitude expected value data that represents, in increments of sampling points, which of multiple amplitude segments the amplitude of a modulated signal waveform that corresponds to the expected value of data to be output from a device under test belongs to. A demodulator performs sampling of the signal waveform to be tested received from the device under test, and generates judgment data that represents, in increments of sampling points, which of the multiple amplitude segments the amplitude of the signal waveform belongs to. A judgment unit makes a comparison between the amplitude expected value data and the judgment data in increments of sampling points.
