EU (e.g., EN 55011) by creating the concept of Group1 and Group2
appears to also cover (in Group 1) *any* generated radio frequency
energy that is used by the equipment. This would include, for example,
radio frequency energy generated by a microprocessor clock circuit in
an industrial machine?s controller.
Have I got this right?
Nearly. EN 55011 is in fact CISPR 11 in a European overcoat. Although
ANSI supports CISPR standards, the FCC uses different, not fully
corresponding, terminology, and puts the two groups of equipment into
different FCC documents (Parts 15 and 18). Group 1 is **more or less
equal** to 'non-intentional radiators' and Group 2 to 'intentional
radiators'.
