TEM cell for simple and cost-effective measurement of radiation and strength Why a TEM cell? A TEM cell (Transverse ElectroMagnetic Cell) is used to house test objects for measuring and testing the radiation or immunity of electronic devices. Typically, radiation is measured in anechoic environments, and the signals are picked up by antennas. Due to bandwidth limitations, different antennas are required to cover the entire frequency range. Furthermore, a significant amount of space is needed, and the cost of the equipment for a standards-compliant setup is enormous. What is needed is an affordable laboratory setup for measuring radiation in your own laboratory before submission to an EMC test facility. The compact TEM cells from Tekbox cover the entire frequency range up to 2 GHz and are also suitable for frequencies beyond that. When used with a spectrum analyzer, products can be tested before and after EMC-related modifications. The test setup with a TEM cell provides valuable information on whether
