Emissions and immunity simulation chamber
What is an emissions and immunity simulation chamber
An emission and immunity simulation chamber, also known as an EMC/EMI chamber, is a specialised laboratory chamber designed to test the electromagnetic compatibility (EMC) and electromagnetic interference (EMI) of electronic devices. These chambers are used to test the emission and immunity of electronic devices, which refers to the device’s ability to emit or resist electromagnetic interference. Tests are conducted by generating electromagnetic fields inside the chamber and measuring the response of the electronic device under test. The chamber is usually a shielded room, designed to prevent external electromagnetic fields from interfering with the test. The walls, ceiling and floor are lined with conductive materials, such as copper or aluminium, which create a Faraday cage that isolates the test equipment from external electromagnetic interference. Inside the chamber are antennas, amplifiers and other test equipment that generate electromagnetic fields at different frequencies and power levels. The electronic device to be tested is placed inside the chamber and connected to the test equipment to measure its response to the electromagnetic fields. Emission tests measure the amount of electromagnetic energy emitted by the device under test, while immunity tests measure the device’s ability to function in the presence of electromagnetic interference.
Emissions and immunity simulation chamber: who to rely
An emissions and immunity simulation chamber is commonly used in the design and testing of a wide range of electronic devices, including medical equipment, aerospace systems and telecommunications equipment, to ensure compliance with regulatory requirements and reliable operation in the presence of other electronic equipment. In this case, you can rely on the expertise and professionalism of GTEM Italia, which over the years has become a real point of reference in the sector. Its chamber, in fact, is designed for radiated immunity measurements at a test distance of 3 metres.
