The present disclosure relates to an over-the-air test apparatus for testing a device under test over-the-air. The test apparatus includes an antenna that is connected with a radio frequency circuit having at least three ports. A first port of the radio frequency circuit is connected with a first path that includes a connector configured to connect a signal analyzer and/or a signal generator with the over-the-air test circuit. A second port of the radio frequency circuit is connected with a second path that encompasses a detector. The second path includes an interface configured to be connected with a power meter, a signal analyzer or a feedback interface of a signal generator. Further, a test system is described.
