Abstract

A measurement system for measurements of a device under test (DUT) is provided. The measurement system includes a first test antenna configured to send radio frequency (RF) radiation to the DUT and to receive RF radiation sent by the DUT. The system further includes a positioning device, including at least one motor, configured to move the DUT about at least one axis of rotation. The system further includes a geometrical fixture configured to absorb RF radiation and to de-couple or shield the DUT from unintended or spurious RF radiation of one or more of the at least one motor and the first test antenna.
