Open TEM Cell


The Open TEM Cell series is an essential tool for engineers performing electromagnetic compatibility (EMC) testing on small devices under test (DUT). These cells are specifically engineered to facilitate both radiated emissions and radiated immunity measurements within a highly controlled and repeatable electromagnetic environment. By establishing a defined characteristic impedance, the cells ensure that field conditions remain stable, which is critical for accurate pre-compliance data collection.

The construction of these cells features a unique open-sided architecture, which significantly simplifies the process of accessing the DUT and managing complex cabling requirements. Unlike enclosed structures, this design allows for real-time adjustments and monitoring during the testing phase, making it highly efficient for troubleshooting and iterative design cycles. The technology utilized ensures that laboratory-grade measurements can be achieved on a standard workbench.

The series offers a diverse range of models to accommodate different device sizes and frequency requirements, including the TBTC0, TBTC1, TBTC2, and TBTC3. Septum heights vary from 27mm to 150mm, while the frequency range extends from 0.09 MHz up to 6000 MHz across the series. These options allow users to select the optimal cell for their specific testing needs, ensuring comprehensive coverage for modern wireless and electronic standards.
