  • Over-the-air test system as well as method for measuring the over-the-air performance of a device under test
    Patent number: 10830811
    Abstract: An over-the-air test system for measuring the radiation performance as a function of temperature of a device under test is described, wherein the device under test has at least one antenna unit and at least one radio frequency circuit. The over-the-air test system comprises a measurement antenna unit, a measurement unit for at least one of signal generation and signal analysis, an enclosure that provides an internal space for accommodating the device under test for testing purposes in a sealed manner, and an atmosphere conditioning system that is configured to adapt the atmosphere within the internal space. The enclosure comprises at least one sealable opening via which the internal space is connectable with the atmosphere conditioning system to adapt the atmosphere within the internal space for the testing. Further, a method for measuring the over-the-air performance of a device under test is described.
