Passing EMC tests mainly test two aspects of a product’s performance. First, does this product cause problems to nearby products(or equipment or human being)? Second, does this product operate as it should be when working with nearby products?
It does also test a product’s own performance. This is what we call power integrity or signal integrity. A product might pass all EMC tests, but fails to operate when released in the market. This is often due to poor power or signal integrity of the product design.
This section discusses the power and signal integrity aspect of a product (or system). To achieve good PI and SI, one need to do it right from the design stage and test the platform during the development stage. You will find lots of interesting tests designed and developed to test your system robustness and performance.
