PROBLEM TO BE SOLVED: To provide a receiving device or the like 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 has a receiving unit 10 that samples a measured signal a transmitted from a DUT 2 to acquire a sample signal d, and an FFT that multiplies the sample signal by a window function to perform an FFT process. When the signal length of the processing unit 21 and the signal to be measured is shorter than the signal length of the first FFT conforming to the communication standard, the second FFT length shorter than the signal length of the signal to be measured is used instead of the first FFT length. The FFT length setting unit 34 set as the FFT length of the FFT process, and the first window function actually set as the window function used for the FFT process when the signal length of the signal to be measured is shorter than the first FFT length. Instead, it includes a window function setting unit 35 that sets an asymmetric second window function whose peak is separated from the center of the window section as a window function.
