摘要 |
A jitter measurement apparatus that measures timing jitter of a signal under measurement having a prescribed repeating pattern includes a sampling section that coherently samples the signal under measurement within a prescribed measurement duration; a waveform reconfiguring section that rearranges ordinal ranks of data values sampled by the sampling section to generate a reconfigured waveform that is a reproduction of a waveform of the signal under measurement; an analytic signal generating section that converts the reconfigured waveform into a complex analytic signal; and a jitter measuring section that measures jitter of the signal under measurement based on the analytic signal.
