Abstract

The present disclosure relates to a system for aligning a measurement system suitable for radio frequency measurement of a device under test. The system includes an alignment device, a measurement module and an indication module. The alignment device includes at least two alignment antennas configured to receive a signal over-the-air from a measurement antenna of the measurement system. The measurement module is configured to measure a phase difference between the at least two alignment antennas receiving the signal. The indication module is configured to indicate the measured phase difference between the at least two alignment antennas or a reference quantity associated with the measured phase difference. Further, a method of aligning a measurement system used for radio frequency measurement of a device under test is described.
