2. How to carry out system qualification tests

2.1 Selection and definition of system for qualification testing

For any system, whether simple or complex, the ideal is to be able to carry out EMC qualification tests on the complete system in its real environment, which is not feasible most of the time. Limitations may include size, non-reproducibility of the electromagnetic environment, system complexity or cost.

To overcome these limitations, there are several possible solutions:

• breaking down the system into sub-systems: in this case, it must be possible to guarantee that elements absent from the system at the time of testing will not jeopardize the results and relevance of qualification;

• select the functions/electrical...
