Hi All, Well, I have been writing again. This month my article is on voltage measurements.
Voltage measurements can give misleading results with some measurements yielding a result that appears nowhere in the circuit of interest! This month's Technical Tidbit at http://emcesd.com is titled "Kirchoff and Faraday Voltage Measurements - Don't Confuse Them." The article discusses two types of voltage measurements and why a measurement may give a result that is quite different than what is happening in the circuit. The link to the article is the measurement picture at the bottom of the main page. Also new on the website is a paper titled "A Method of Accurately Measuring Shielding Effectiveness of Materials in Electronic Products" at the bottom of the "Technical Information and Downloads" section. This is a white paper I wrote for one of my clients on measuring shielding effectiveness of materials that are close to the source (where plane wave measurements are not valid) such as in a cell phone or other small hand held device. For those of you who missed the IEEE EMC Symposium, I will be posting pictures from the Symposium in a few weeks.
