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 unitthat receives a frame transmitted from a DUT, a determination unitthat determines whether or not a header of the frame has been normally received by the reception unit, an acknowledgment transmission unitthat transmits the acknowledgment frame to the DUTwhen the determination unitdetermines that the header has been normally received by the reception unit; and a measurement unitthat performs the measurement on the frame determined by the determination unitthat the header has been normally received by the reception unit

Measurement device and measurement method

A measurement deviceincludes a reception unitthat receives a frame transmitted from a DUT, an MCS determination unitthat determines whether or not a received MCS index of a frame received by the reception unitmatches a predetermined MCS index for comparison, a transmission unitthat transmits a notification signal to the DUT when the MCS determination unitdetermines that the received MCS index matches the MCS index for comparison, and does not transmit the notification signal to the DUT when the MCS determination unitdetermines that the received MCS index does not match the MCS index for comparison, and a measurement unitthat measures data under measurement included in the frame in which it is determined that the received MCS index matches the MCS index for comparison.

A measurement device includes a capability information acquisition unit that acquires capability information indicating capability of a DUT set for each item determined in advance, a setting unit that sets a measurement condition of the DUT, a measurement unit that performs measurement of the DUT on the basis of the measurement condition, a capability determination unit that notifies of capability excess information indicating that the measurement condition regarding a certain item among the measurement conditions exceeds capability determined for each item in advance on condition that the measurement condition regarding the item among the measurement conditions has been set to exceed the capability determined for each item in advance, and a display unit that displays capability excess information.

A measuring apparatusincludes: a transmission and reception unitwhich wirelessly communicates with devicestounder test (DUTs); a measurement unitwhich receives data from the DUTs through the transmission and reception unit, measures the DUTs based on the received data and outputs measurement results; a display unitwhich displays predetermined information regarding the measurement; a disconnection related information acquisition unitwhich, on the condition that a connection state of the wireless communication has been changed to a disconnected state, acquires disconnection related information including information indicating a reason for changing to the disconnected state and information on a state immediately before the disconnected state; and a display control unitwhich performs control to display the disconnection related information on the display unit
