CISPR 25 Conducted Emissions Current (CEI) Grounding Scheme

An incorrect DUT grounding scheme can easily make the difference between compliance and non-complian

An incorrect DUT grounding scheme can easily make the difference between compliance and non-compliance to CISPR 25 CEI limits. Sometimes we have to evaluate CEI from two modules, one used as DUT and the other one used as DUT's load (e.g. Module #1 is a PWM maker while Module #2 is an LEDs Lamp).
