A shield box is typically designed to accommodate only the Device Under Test (DUT). Its primary purpose is to provide an electromagnetically isolated environment that minimizes external interference and prevents the leakage of test signals. The DUT can be connected to measurement equipment through RF, power, or signal interfaces integrated within the enclosure, enabling testing under controlled conditions.
To ensure consistent test conditions and improve measurement accuracy, dedicated fixtures are commonly installed inside the shield box to secure the DUT in a fixed position and orientation. This helps reduce measurement variations caused by differences in DUT placement, angle, or contact conditions, thereby enhancing the stability, repeatability, and reliability of test results.
