Abstract

The invention relates to a method of performing a measurement of a device under test (12) by using an antenna array (16), the method comprising the steps of: - Providing an antenna array (16) that comprises several antenna elements (18), - Providing a device under test (12) configured to communicate over-the-air, - Locating the device under test (12) at a first test location, thereby establishing a first relative distance between the device under test (12) and the antenna array (16), - Performing a first measurement over-the-air when the first relative distance is provided between the device under test (12) and the antenna array (16), thereby obtaining first measurement results, - Moving the antenna array (16) and/or the device under test (12), thereby establishing a second relative distance between the device under test (12) and the antenna array (16), and - Performing a second measurement over-the-air when the second relative distance is provided between the device under test (12) and the antenna array (16), thereby obtaining second measurement results, wherein a quiet zone is established, in which the device under test (12) is located, and wherein the size of the quiet zone is derived from a combination of at least two transfer functions associated with the first measurement results and the second measurement results. Further, a measurement system (10) is described.
