Measurement apparatus, measurement method and computer readable medium

A measurement method comprising:

• outputting a binary digital signal configuring a multi-tone waveform;
• acquiring an analog signal waveform generated in response to application of the digital signal to a device under test;
• calculating a frequency characteristic of the device under test from the acquired waveform;
• and
• determining a quality of the device under test based on the frequency characteristic that is calculated, wherein in determining the quality of the device under test, the device under test is determined to be faulty when the frequency characteristic that is calculated is out of a reference range, and
• wherein the binary digital signal is obtained by repeatedly outputting a signal upconverted by multiplying a pseudo-random binary sequence (PRBS) signal by a repeating rectangular wave with a reference frequency and a reference duty ratio.

A non-transitory computer readable medium having stored thereon a program for causing a computer to function as:

• a signal source configured to output a binary digital signal configuring a multi-tone waveform;
• a waveform acquisition unit configured to acquire an analog signal waveform generated in response to application of the digital signal to a device under test;
• a computation unit configured to calculate a frequency characteristic of the device under test from the waveform acquired by the waveform acquisition unit;
• and
• a determination unit configured to determine a quality of the device under test based on the frequency characteristic calculated by the computation unit, wherein the determination unit determines the quality of the device under test to be faulty when the frequency characteristic calculated by the computation unit is out of a reference range, and
• wherein the signal source is configured to repeatedly output a signal upconverted by multiplying a pseudo-random binary sequence (PRBS) signal by a repeating rectangular wave with a reference frequency and a reference duty ratio.
