4. Common errors in EMC CE marking tests

Now that we've covered a few classic EMC tests, we'll look at the most common errors to be avoided when designing equipment.

These errors, identified by customers carrying out laboratory tests, more often than not result in non-compliant equipment.

EMC improvement is achieved through various types of action:

• reduction of external factors; for example, we can reduce disturbances due to electrostatic discharges by reducing humidity in the premises, using antistatic flooring, etc. ;

• equipment hardening; an electronic system can be "hardened" by choosing components that are the least sensitive to disturbances (different technological families: TTL, CMOS, etc.);

• coupling reduction: for a given external source, the level of disturbance...
