ABSTRACT:
Provided is a test apparatus, a calibration method, a program causing a computer to perform as a test apparatus, and a recording medium storing the program. The test apparatus includes a response characteristic detecting section that detects a difference between a response time of the comparator for a rising waveform and a response time of the comparator for a falling waveform, based on measurement results, obtained by the comparator, of the waveforms and corresponding reflected waveforms, The response characteristic detecting section calculates a difference between output characteristics of the rising waveform and the falling waveform output from the driver, based on the measurement results from the comparator of the waveforms and the corresponding reflected waveforms, and corrects a difference between the response times of the comparator based on the difference between the output characteristics.
