Abstract: An arbitrary waveform generation device is an arbitrary waveform generation device that generates, from an arbitrary waveform of a first electrical signal, an arbitrary waveform of a second electrical signal having a frequency higher than a frequency of the first electrical signal, and includes: a modulator that modulates, with the first electrical signal, an optical carrier wave which is dispersed to have a central wavelength that varies with time; a dispersion compensator that performs dispersion compensation on the optical carrier wave modulated with the first electrical signal; and a photoelectric converter that converts the optical carrier wave which has been dispersion-compensated into an electrical signal to generate the second electrical signal.
