Shielding of an EMG Machine Utilizing a Conductive Tent
Testers seek to remedy the longstanding problem of “noisy’ responses from an EMG instrument. Terence P. O’Laughlin and Michael J. Oliver, MAJR Products, Saegertown, Pennsylvania, USA INTRODUCTION This paper presents a shielding methodology and test in which an electromyography (EMG) instrument is shielded from spurious electromagnetic and radio frequency interference … [Read more...]
Hybrid Power Amplifier Modules & Custom Solutions Offer Flexibility in Numerous RF Apps
A new line of wideband, hybrid power amplifier modules (HPMs) from AR RF Microwave Instrumentation covers the 6- to 18-GHZ frequency range. These hybrid modules require only a single DC volt source and are 50-ohm “cascadable” building blocks with output powers up 37 dBm. The six new hybrid power modules have excellent typical gain flatness, excellent noise performance, and low … [Read more...]
EMC Society Technical Committees
What is a technical committee? The technical committees play an important role in the overall success of the EMC Society by promoting activities in their fields and providing expert knowledge and assistance to generate and review technical papers, to organize and operate sessions at symposia, to generate and develop standardsn and to evaluate the “state of the art” in EMC … [Read more...]
Voltage Sag Testing for Industrial Equipment—and a New Power Quality Measurement Technology
An electrical product should be able to ride through any regular voltage sag. Andreas Eberhard, Power Standards Labs, Alameda, California, USA Immunity from voltage sags is vital for reliable operation of our ever-more-sophisticated electronic controls and equipment. Every electrical product should be able to ride through typical voltage sags, but in many cases the first sag … [Read more...]
