An electromagnetic compatibility (EMC) or Electromagnetic Interference (EMI) chamber is a highly specialized piece of test equipment used in the testing of electronic devices against regulatory standards concer... Read More...
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. Therefore, the most important question that must be answered by any company manufacturing finished products or component parts is “What should my company do and how should I do it?”
This article discusses the reflections on a transmission line at the capacitive and inductive loads.
Many of the EMI/EMC problems in electronic products can be avoided or solved with ground (GND) planes. But, be sure your GND plane is a true GND plane.
Will SEED (system efficient ESD design) truly get us away from the trial and error drudgery of system level ESD design?
The regular “Banana Skins” column was published in the EMC Journal, starting in January 1998.
