ABSTRACT:
There is provided a phase measurement apparatus for measuring a phase of a signal under measurement. The phase measurement apparatus includes a sampling section that samples the signal under measurement at timings indicated by a sampling clock supplied thereto, a jitter injecting section that injects jitter to at least one of the signal under measurement which is to be input into the sampling section and the sampling clock, and a phase calculating section that calculates the phase of the signal under measurement based on a result of the sampling performed by the sampling section.
