摘要

PROBLEM TO BE SOLVED: To provide a receiving device capable of performing FFT processing with high reliability, which can cope with a case where the signal length of a signal to be measured is short outside the standard in a test involving FFT processing. SOLUTION: A test apparatus 1 performs an FFT process by multiplying a receiving unit 10 for sampling a measured signal a transmitted from a DUT 2 and acquiring a sample signal d and a window function on the sample signal. Communication standard as the FFT processing unit 21, the signal length calculation unit 31 that calculates the signal length of the measured signal from the sample signal acquired by the receiving unit, the calculated signal length of the measured signal, and the FFT length of the FFT processing. When the signal length of the signal to be measured is shorter than the first FFT length as a result of comparison between the comparison unit 33 for comparing with the first FFT length conforming to the above, instead of the first FFT length, It includes an FFT length setting unit 34 that sets a second FFT length shorter than the signal length of the signal to be measured as the FFT length of FFT processing in the FFT processing unit.
