The use of ceramic feed-through capacitors, as well as specific filter designs and installation techniques, can make cardiac pacemakers immune to EMI ROBERT A. STEVENSON, Maxwell Technologies Carson City, Nevada, USA Under the coordination of Wireless Technology Research, L.L.C. (WTR), the interaction between cellular phones and cardiac pacemakers has been widely … [Read more...]
Introduction to Measurement Uncertainty for Antenna Calibration
Critical items need to be identified for a particular calibration method MIKE HOWARD The purpose of this article is to introduce the reader to basic elements and concepts in the computation of measurement uncertainty for antenna calibration. Measurement uncertainty is a tool used to account for errors associated with a measurement system. Uncertainty can be used for … [Read more...]
Understanding the Measurement Uncertainties of the Bicon/Log Hybrid Antenna
Surge damage as a result of long cables connected to low voltage data systems can be prevented RICHARD MEININGER & ROBERT BLOUCH Since their first introduction in 1994 at the Roma International Symposium on EMC, bicon/log hybrid antennas have become very popular in EMC labs worldwide. Because there are no band breaks in frequency sweep, test time and effort are reduced. … [Read more...]
