Abstract:
A method for measuring beam steering characteristics of a device under test using a measurement system comprising a probe array with at least two field probes. The field probes can be arranged at different angles with respect to the device under test. A reference unit for calibrating the probe array is provided. At least two calibration measurements with different main radiation directions of the reference unit are performed wherein a predefined number of field probes of the probe array is used for measuring the radiation pattern of the reference unit. A calibration dataset for at least each field probe of the predefined number of field probes and each radiation direction is generated and stored. The reference unit is replaced by a device under test such that the device under test is located at the same measurement position as the reference unit was during the calibration measurements. A measurement of the device under test is performed by using the predefined number of field probes of the probe array.
