Method for downlink power tests, test system as well as test setup

A method for downlink power tests of a device under test comprising: generating a downlink signal with a predefined downlink power level in a quiet zone at the device under test; measuring a first absolute power level received by the device under test; determining whether the measured first power level lies within a predefined first range; repeatedly measuring subsequent power levels received by the device under test; and determining by the control unit whether the measured subsequent power levels lie within a predefined second range around the measured first power level with respect to the current downlink power level. Further, a test system and a test setup for downlink power tests are shown.
