Abstract
Provided is a measurement apparatus including 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, and a computation unit configured to calculate a frequency characteristic of the device under test from the waveform acquired by the waveform acquisition unit, in which 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.
