Abstract
A measurement system is provided. The measurement system comprises a device under test comprising at least one antenna, at least one measurement antenna, and a signal analysis unit. In this context, the location of the at least one antenna of the device under test is unknown with respect to the device under test, whereas the signal analysis unit is configured to perform at least one near-field measurement with respect to the device under test with the aid of the at least one measurement antenna. In addition to this, the signal analysis unit is further configured to locate the at least one antenna of the device under test on the basis of the at least one near-field measurement in order to obtain position data of the at least one antenna of the device under test.
