Abstract

A system for over-the-air testing of a device under test includes a measurement antenna, a reference antenna, a device under test capable of wirelessly transmitting and/or receiving complex radio frequency signals, and an analyzer. The analyzer has at least two ports, wherein the reference antenna is connected with a first port of the analyzer. The measurement antenna is connected with a second port of the analyzer. The analyzer is capable of determining a phase difference and a power ratio of radio frequency signals received via the measurement antenna and the reference antenna. The analyzer is capable of performing an IQ analysis on complex radio frequency signals. Further, a method of over-the-air testing of a device under test is disclosed.
