1. A method of measuring a total radiated power of a device under test by a test system, wherein the test system has a measurement antenna, a positioning system and a control and/or measurement equipment, wherein the device under test is positioned on the positioning system, and wherein the method comprises:
moving the device under test with respect to an azimuth axis and an elevation axis by the positioning system;
transmitting a time dependent signal by the device under test, wherein the device under test is assigned to certain time frames during which the device under test is permitted to send, resulting in the time dependent signals; and
recording a correlation between the control and/or measurement equipment and a respective spherical position of the positioning system,
wherein the control and/or measurement equipment transmits a request signal to the positioning system to return its exact spherical position.
