October 2010 saw the 74^th IEC General meeting in Seattle, Washington, USA. Within the IEC, its special committee CISPR (Comite International Special des Perturbations Radioelectriques –International Special Committee on Radio Interference) came together and this article reviews some of the key projects discussed at that meeting. The activities of IEC TC 77, a parallel committee to CISPR developing the IEC 61000 series and of equal importance, did not meet in Seattle and hence will not be discussed here except for the JTFs (Joint Task Forces) that exist in common with CISPR Subcommittee A, responsible for the basic standard CISPR 16, which will be the main focus of this first part of a two part article. In the second part of the article (to be published in a subsequent edition of this magazine), we will continue with the CISPR product standards and the Joint Task Forces (JTFs) existing between the different subcommittees as well as between CISPR subcommittees and IEC SC 77 B.

The start of a new year is a time when, traditionally, we reflect on the progress we made during the year passed and set our goals for the new year. More often than not, your professional development goals include training or some form of higher education to expand or refresh your technical knowledge. We’ve queried training resources in our niche industry to provide you with an overview of affordable solutions to meet your training goals in 2011. You’ll find here sources of compliance related seminars and workshops offered online and on location, public and private.

In the rush to complete RF immunity testing on schedule, it is not all that unusual to overlook inherent test equipment limitations. While some test equipment characteristics such as power amplifier harmonics are obviously a limiting factor, the broadband characteristics of antennas, directional couplers, power meters and isotropic field probes can hardly be considered a limitation for most applications. However, when used with power amplifiers exhibiting significant harmonic distortion in Immunity test systems, the broadband characteristics of these devices can result in measurement uncertainty and unacceptable errors.

Standards are increasingly important in our modern global economy – supply chains can be dizzyingly complex, and implementing the economic theory of comparative advantage has been more and more possible as the relative cost of transportation has declined over the years. Since the 1890s, the United States has been the world’s top manufacturing country. The world continues to change. Recently it was reported that China surpassed Japan as the second largest economy, and it is estimated that China will soon surpass the United States.
