Running EMC/EMI tests requires specific equipment. By achieving immunity, devices can function as normal when encountering unwanted emissions. In the case of susceptibility, testing shows how devices react in the presence of radio frequency waves, where there is a tendency for breakdown to occur. On the emissions front, tests point out unwanted emissions and potential countermeasures that could reduce the electromagnetic energy that is generated. When thinking about EMC/EMI testing, we can divide its focus into two classes: emissions and susceptibility. Licensed under CC BY-SA 3.0 IGO, via Flickr Creative Commons. This question is at the heart of EMC/EMI testing, and finding the answer helps us modify operations as needed.Ī spacecraft undergoes EMC/EMI testing. To showcase this, we’ll look at a well-known equipment choice in EMC/EMI testing…ĭoes an electronic or electrical device operate as it should in a common electromagnetic environment? Before such a product is of the quality and safety to bring to market, this is an important question to address. RF modeling is a useful approach to analyzing and optimizing such devices, generating greater confidence in the measurements they obtain. This testing equipment must be designed so that it delivers precise measurements that are reflective of real-world performance. Just as important as these tests is the equipment used to perform them. Compliance testing is used to ensure that various products, processes, and systems meet standard requirements.
