Abstract

The invention relates to an over-the-air (OTA) test system for measuring a performance of a device under test (DUT). The test system comprises an over-the-air (OTA) measurement chamber provided with at least one feedthrough for at least a first air hose and a second air hose. The test system further includes a thermally isolated hollow body inside the OTA measurement chamber, in which the DUT is positioned having at least two openings for connecting a first end of each of the first and the second air hose, and at least one sensor having a connection wire, located within the thermally isolated hollow body. Advantageously, the sensor connection wire is fed through one of the two openings into the thermally isolated hollow body.
