  • Publication number: 20190250199
    Abstract: Measurement arrangement and method for measuring an electromagnetic field. It is for this purpose that a measurement probe is arranged on a mechanical probe positioning structure and moved along a number of one or more circular tracks. In this way, the measurement probe can be subsequently located at multiple different spatial positions and the corresponding electromagnetic signal can be measured. Accordingly, properties of an electromagnetic field can be determined by taking into account the measured electromagnetic signal with respect to the related spatial position.
