11.4. EMI
EMI requirement is given here as a target, since it is also PCB dependent. Any EMI issue will have to be solved
on common basis with the customer.
Radiated disturbance electromagnetic quietness test, according to Renault 36-00-808/--E document:
• Permanent broadband limit (Renault 36-00-808/--E document diagram p98)
• Narrow band limit (Renault 36-00-808/--E document diagram p99)
11.5. Power supply micro-interruptions
