MEASURING APPARATUS AND MEASURING METHOD

To provide a measuring apparatus and a measuring method capable of realizing measurement of a MIMO system measured apparatus with an inexpensive configuration, and capable of dealing flexibly even with measurement of the measured apparatus where the number of antennas is changed.SOLUTION: A measuring apparatus 50 has two measurement instruments 51A, 51B of a SISO system, where the measurement instrument 51A is set as a main measurement instrument, and the measurement instrument 51B is set as a sub-measurement instrument. The main measurement instrument 51A connects each measurement instrument 51A, 51B with DUT1 by wireless local area network, by transmitting signals of single stream while synchronizing the transmission operation timing of each transmission section 73A, 73B, transmits a frame for measurement containing data for measurement from each transmission section 73A, 73B, during connection of wireless local area network, and measures reception characteristics of the DUT1 on the basis of an ACK indicating that the data for measurement from the DUT1 for the frame for measurement was received.SELECTED DRAWING: Figure 5 【課題】ＭＩＭＯ方式の被測定装置の測定を安価な構成により実現でき、アンテナ本数が変更された被測定装置の測定にも柔軟に対応可能な測定装置及び測定方法を提供する。【解決手段】測定装置５０は、ＳＩＳＯ方式の２つの測定機器５１Ａ、５１Ｂを有し、測定機器５１Ａが主測定機器、測定機器５１Ｂが副測定機器として設定される。主測定機器５１Ａは、各送信部７３Ａ、７３Ｂの送信動作タイミングを同期させつつそれぞれ単一ストリームの信号を送信させることにより各測定機器５１Ａ、５１ＢとＤＵＴ１とを無線ＬＡＮにより接続し、該無線ＬＡＮの接続中、各送信部７３Ａ、７３Ｂから測定用データを含む測定用フレームを送信させるとともに、当該測定用フレームに対するＤＵＴ１からの測定用データを受信したことを示すＡＣＫに基づいてＤＵＴ１の受信特性を測定する。【選択図】図５
