This two-day class provides a unique blend of theory, applications, and numerous hardware demonstrations to describe effective and sometimes not-so-effective PCB design advice that we often hear from electrical engineers and EMC “experts.” The real-time demonstrations use a spectrum analyzer, oscilloscope and signal generators to illustrate inductance, common-impedance coupling, and ground loops in PCBs, cables, and systems. Specific examples of single-point, multi-point, “good”, and “bad” grounds will be discussed. Examples of integrated circuit application notes that give bad EMC design advice will also be studied during the class.
