Provided is a sampling apparatus that samples a signal under measurement, including a sampling section that samples the signal under measurement with a plurality of sampling phases at non-uniform intervals for each sampling repetition cycle; and an inverting section that cancels out a replica that is not an observation target, from among the replicas in a sampling band of the signal under measurement and the replicas in the sampling band of a frequency component of the signal under measurement, by inverting signs of values of the signal under measurement sampled with at least one sampling phase from among the plurality of sampling phases.
