Methods and measurement systems for precisely evaluating a device under test
A method includes defining a Center-of-Radiation Reference for a device under test, the CORR indicating a reference origin of an electromagnetic wave pattern formable with the DUT; determining a 3-dimensional orientation information with respect to the CORR, the 3-dimensional orientation information indicating a direction of the electromagnetic wave pattern; and providing the CORR and the 3-dimensional orientation information to a measurement system.
OVER THE AIR MEASUREMENT MODULE
An over the air measurement module comprises an antenna, adapted to receive a first measuring signal from a device under test or to transmit a second measuring signal to the device under test. It also comprises an analog signal processor, directly connected to said antenna, adapted to reduce a frequency of the received first measuring signal, resulting in a frequency reduced first measuring signal, or adapted to increase a frequency of a frequency reduced second measuring signal, resulting in the second measuring signal. It also has a connector connected to said analog signal processor and is adapted to output the first frequency reduced measuring signal or is adapted to receive the second frequency reduced measuring signal.

MASSIVE-MIMO ANTENNA MEASUREMENT DEVICE AND METHOD OF MEASURING DIRECTIVITY THEREOF
To minimize a measurement range when a near field measurement is performed on the directivity of a massive-MIMO antenna, and prevent the accuracy of measurement from deteriorating. Beam direction detection means 33 causes a probe antenna 12 to perform a rough scanning in a state where an electromagnetic wave radiation plane 1a of a test antenna 1 is directed toward a reference direction directly facing a measurement plane P, and detects the direction of a beam radiated by the test antenna 1 on the basis of a received signal thereof. Antenna direction change means 34 changes the direction of the test antenna so that the detected direction of a beam is directed toward the center of the measurement plane P.
OVER THE AIR MEASUREMENT MODULE
An over the air measurement module comprises an antenna, adapted to receive a first measuring signal from a device under test or adapted to transmit a second measuring signal to the device under test. Furthermore, the over the air measurement module comprises a mixer, directly connected to said antenna, adapted to reduce or increase a frequency of the received first measuring signal, resulting in a frequency reduced or increased first measuring signal, or adapted to increase or reduce a frequency of a frequency reduced or increased second measuring signal, resulting in the second measuring signal. In addition to this, the over the air measurement module comprises a first connector, connected to said mixer, adapted to input a local oscillator signal into the mixer for frequency conversion.
