Abstract: A test system for testing a device under test is described. The test system includes an anechoic chamber for encompassing a device under test to be tested by means of radio frequency radiation. The anechoic chamber has a wall with an opening provided in the wall. The test system also has a feedthrough assembly for transporting a fluid into the anechoic chamber or from the anechoic chamber. The feedthrough assembly has a pipe that extends through the opening such that the pipe is fed through the opening. The pipe is routed such that radio frequency radiation is prevented from leaving the anechoic chamber via the pipe. Furthermore, a feedthrough assembly is described.

Abstract: An over the air, OTA, test chamber for testing at least one device under test, DUT, provided within the OTA test chamber which includes a thermal bubble component adapted to receive the device under test, DUT, comprising an air inlet adapted to supply air into the thermal bubble component, an air outlet adapted to remove air from the thermal bubble component and an airstream diffusor provided at the air inlet and adapted to diffuse an airstream supplied by the air inlet within the thermal bubble component.

Abstract: A fixture and a measurement system are provided. The fixture is adapted for electrically connecting a measurement device with a device under test, DUT, in particular a wireless DUT, and for mechanically holding the DUT. The fixture comprises a clamp for clamping the DUT; a male plug for engaging a mating socket of the DUT; and an electrical cable connected to the plug on one end and connectable with the measurement device at its other end. The fixture is arranged to mechanically hold the DUT such that the DUT can be rotated relative to the measurement device. The fixture reduces a shielding effect in respect of antenna modules of the DUT.

Abstract: A system for calibrating radio frequency test chambers is provided. The system comprises an antenna array with a plurality of antenna elements arranged in a three dimensional configuration, a plurality of power measuring units downstream to the plurality of antenna elements and a processing unit. In this context, the plurality of power measuring units output a power from each antenna elements corresponds to a radiation pattern generated by an incident test signal. The processing unit is configured to analyze the power distribution of the test signal in order to calculate a calibration.

Abstract: The invention relates to a system for calibrating a measurement antenna of an RF test arrangement, comprising: a calibration antenna, and a fixture, wherein the calibration antenna is mounted to the fixture, and wherein the fixture comprises an aperture for removably mounting the fixture on the measurement antenna, wherein the calibration antenna is arranged at a fixed distance from the measurement antenna if the fixture is mounted on the measurement antenna.
