Abstract
An over-the-air (OTA) measurement system is described. The OTA measurement system includes a plurality of measurement antennas, a DUT positioner, and a controller (e.g., control circuit). The DUT positioner is configured to position a device under test at a test location. At least two measurement antennas of the plurality of measurement antennas are arranged at different distances from the test location. The at least two measurement antennas are arranged at different elevation angles and/or at different azimuth angles with respect to the test location. The controller is configured to control the DUT positioner to rotate the device under test at the test location in azimuth and/or elevation. The controller is configured to control the DUT positioner to rotate the device under test into a first orientation for a first OTA power measurement by a first one of the at least two measurement antennas. The controller is configured to control the DUT positioner to rotate the device under test into a second orientation for a second OTA power measurement by a second one of the at least two measurement antennas. A relative orientation between the device under test in the first orientation and the first one of the at least two measurement antennas is the same as a relative orientation between the device under test in the second orientation and the second one of the at least two measurement antennas. Further, an OTA measurement method for performing OTA measurements on a device under test by an OTA measurement system is described.
