When do we need an EMC pre-compliance lab?

Instead of going directly to a certification house, you use an engineering-focused EMC testing lab that can run pre-compliance checks, debug issues and tell you when the design is ready for the formal test. This guide explains when it makes sense to use an EMC pre-compliance lab, what happens in those sessions, and how TPS approaches pre-compliance for power supplies, industrial equipment and integrated power systems.
