Open TEM Cells for EMC Pre-Compliance Testing
Open TEM cells are specialized stripline devices used for pre-compliance radiated emission and immunity testing of electronic devices in a lab environment. They allow engineers to detect and analyze electromagnetic emissions and immunity behavior of products before sending them to a formal compliance lab, helping reduce redesign risk and testing costs. The open design, without side walls, makes it convenient to place the device under test (DUT) and observe changes in radiated emission performance during design iterations. These TEM cells work with a spectrum analyzer or EMI receiver to produce a reliable indication of the DUT’s EMC performance.
