In its current form, IEEE Std 149 “IEEE Standard Test Procedures for Antennas” is a marginally useful document. While the standard is a good source for interesting and pertinent information, the document has not undergone a significant update since 1979. The changes to the new version of the IEEE Std 149 will make the document an essential reference in any laboratory that conducts antenna measurements.
This article offers an alternative to the CB route of compliance to meet the new European safety standard EN 62368-1, Audio/video, information and communication technology equipment - Safety requirements, for equipment having an existing IEC 60950-1 CB certification.
The elements of a program to deal with pre-sale and post-sale safety issues are well-known. But the specifics of what elements should be used and how by a particular manufacturer are often unknown.
