Hello Group, I am in search of opinions regarding the acceptable EUT configuration for radiated emissions testing. If a system is comprised of one or more independent shelf-level products (e.g. one shelf in a rack or several racks full), at what level is it acceptable to test? Assume that the system can be sold as one independent fully functional "shelf" or as numerous interconnected shelves (interconnection just increasing "system" capacity). For example, one shelf could be sold and deployed, then 6 months later another shelf added (cabled up to the first), and so on, etc.
1. Would it be acceptable to test at the "shelf" level? 2. If not, where is the line drawn? Two? Ten? In a typical CO you may see racks and racks of the same equipment shelves/chassis - chances are, they were not all tested together - where is it reasonable to stop? FCC (ref. ANSI C63.4)/EN300386/GR1089 have some guidance, differing slightly, but not clear. Any and all opinions/experiences from the group are welcome. Thanks and Regards, Scott Lemon Caspian Networks ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
