Inexpensive Radiated Immunity Pre-Compliance Testing
As an EMC consultant, it seems that lately I’ve run into many client projects where radiated immunity has cropped up as the major issue. One reason for this may be the trend in using digital and analog circuits that are powered by 3.3 volts, and lower, which decreases noise margins significantly. Sensitive analog circuitry is also greatly affected. The compliance testing for … [Read more...]
MIT Study Sparks White Sands-SunZia Interference Debate
A new Massachusetts Institute of Technology study on the potential impacts of the proposed SunZia transmission line on White Sands Missile Range validates concerns regarding the project, a U.S. state lawmaker said earlier this week. Speaking to reporters during a telephone conference call on Tuesday, U.S. Congressman Steve Pearce of New Mexico said the study, which has not … [Read more...]
