ABSTRACT:
There is provided an arbitrary waveform generator that generates an arbitrary waveform. The arbitrary waveform generator includes a waveform pattern generating section that generates pattern data showing a pattern of the arbitrary waveform, a digital-analog converting section that outputs the arbitrary waveform based on the pattern data, and a correction processing section that corrects the pattern data and inputs the corrected data into the digital-analog converting section based on a value made by differentiating the pattern data and a time constant of a path through which the arbitrary waveform output from the digital-analog converting section passes.
