Abstract

An over-the-air measurement chamber is provided for performing measurements with respect to a device under test. The over-the-air measurement chamber includes a thermally isolated space inside the over-the-air measurement chamber, a positioner for positioning the device under test, and a first gas guiding means for intake of a gas and a second gas guiding means for outtake of the gas. The positioner comprises an inner portion and an outer rotational unit. The first and second gas guiding means are fed into the inner portion of the positioner through a hollow rotational axis of the outer rotational unit.
