Hi Thanks for the latin lesson John.
Equipment which is inherently benign in terms of electromagnetic compatibility is excluded from the scope of the EMC Directive25. Equipment is considered inherently benign in terms of electromagnetic compatibility if: * its inherent physical characteristics are such that it is incapable of generating or contributing to electromagnetic emissions which exceed a level allowing radio and telecommunications equipment and other equipment to operate as intended; and, * it will operate without unacceptable degradation in the presence of the electromagnetic disturbance normally present in its intended environment. Both conditions need to be met in order to classify equipment as inherently benign. I don't yet see that this excludes cards from compliance. Does anyone know how much power these cards draw.
