This document describes equipment inspection and radio frequency (rf) electromagnetic field measurement procedures for evaluation of rf industrial, scientific, and medical (ISM) equipment installed in the user's facility. The term, ISM equipment, as used here, includes equipment that generates rf energy for purposes other than radio communications, to cause physical, chemical, or biological changes; for example, industrial heaters (dielectric and induction), medical diathermy, ultrasonic equipment, rf plasma devices, and rf stabilized welders. These procedures are designed to help ensure that the equipment does not interfere with radio communications, navigation, and other essential radio services. The engineer responsible for the measurements should take all reasonable precautions to ensure that the maximum emission from the ISM equipment under test (EUT) has been measured. Radio frequency field-strength measurements of installed ISM equipment may be required if any of the following conditions exist:1 The emission from the EUT was not measured by the manufacturer. 2 Because of its size or special operating conditions, the EUT could not be tested before installation. 3 Installed ISM equipment is suspected of causing interference. 4 ISM equipment has been modified in a way that could affect its rf emissions. 5 As the equipment ages, there is a question about its continued compliance. Etc.

This accessible, new reference work shows how and why RF energy is created within a printed circuit board and the manner in which propagation occurs. With lucid explanations, this book enables engineers to grasp both the fundamentals of EMC theory and signal integrity and the mitigation process needed to prevent an EMC event. Author Montrose also shows the relationship between time and frequency domains to help you meet mandatory compliance requirements placed on printed circuit boards. Using real-world examples the book features:. Clear discussions, without complex mathematical analysis, of flux minimization concepts. Extensive analysis of capacitor usage for various applications. Detailed examination of components characteristics with various grounding methodologies, including implementation techniques. An in-depth study of transmission line theory. A careful look at signal integrity, crosstalk, and termination.
