Candace Suriano Suriano Solutions John Suriano Nidec Automotive Motors Americas PART 1: MY CELL PHONE CAN TALK TO ME IN STEREO Dear John, I am snowed in here at home with the kids. You may be in an EMC lab solving some tough issues, but I’ve been very busy here at home with some interesting problems of my own. We’ve been bothered by the behavior of our computer … [Read more...]
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...]
EU Radio Equipment Directive to Require Universal Phone Charger
European Union politicians voted last week in favor of an update to radio equipment that would establish guidelines for a universal mobile phone charger and enact new standards for radio equipment. According to EU officials, the new Radio Equipment Directive aims to keep up with the growing number of “radio equipment devices” and ensure they do not interfere with each other by … [Read more...]
Software Option for EMC Testing in Line with New CISPR Standard
Test and measurement equipment provider Rohde & Schwarz has introduced a new software option for EMC tests on multimedia devices in line with the new CISPR 35 standard. Expected to be adopted in late March, the CISPR 35 EMC standard prescribes future disturbance signal testing requirements for multimedia equipment and will combine the current test standards for devices and … [Read more...]
