Abstract:
A system for near-field measurement of a device under test in a far-field environment is provided. The system comprises a communication unit adapted to establish a far-field connection with the device under test. The system further comprises a measuring unit adapted to measure a magnitude and a phase of at least two field components. Moreover, the system comprises a processing unit adapted to perform far-field to near-field and/or near-field to near-field transformation of the field components in order to calculate field components at a specific surface in the near-field of the device under test.
