Abstract: A first shift unit (14) that shifts an amplitude value of the I baseband signal and an amplitude value of the Q baseband signal in a lower direction by the predetermined number of bits so that the predetermined number of lower bits thereof have a value after a decimal point, a first rounding unit (15) that rounds-to-even the amplitude value of the I baseband signal and the amplitude value of the Q baseband signal shifted by the first shift unit (14) with a rounding width of 1 in decimal notation, and a first averaging unit (16) that respectively calculates a time average of the amplitude value of the I baseband signal and the amplitude value of the Q baseband signal rounded by the first rounding unit (15) are included.

Abstract: A measurement device and a measurement method capable of performing measurement on a device under test while maintaining a desired high data rate even under poor communication conditions such as occurrence of retransmission of a frame from a device under test in a wireless communication connection are provided. The measurement device includes a reception unit 14 that receives a frame transmitted from a DUT 1, a determination unit 16 that determines whether or not a header of the frame has been normally received by the reception unit 14, an acknowledgment transmission unit 13b that transmits the acknowledgment frame to the DUT 1 when the determination unit 16 determines that the header has been normally received by the reception unit 14; and a measurement unit 17 that performs the measurement on the frame determined by the determination unit 16 that the header has been normally received by the reception unit 14.
