Determining Semi-Anechoic Chamber Resonance as a Source of Radiated Emission Measurement Variation Between Chambers and Comparing to OATS Measurements
INTRODUCTION This article describes the lack of an acceptable correlation between anechoic chamber and open field test site radiated emission measurements, which were described in reference 1 in 2000, as well as a lack of correlation between chambers. It was found that emission measurements, which were over the limits in one facility, would pass in another. The lack of a … [Read more...]
Troubleshooting Radiated Immunity for Medical Products – Case Study
Introduction Companies making medical products have much more stringent requirements now that the new IEC 60601-1-2 (Edition 4) became effective June 17, 2017. One of the many changes included increased radiated immunity requirements in several specific wireless and communications bands (Table 1). Highlights of all the changes are included in Interference Technology’s free … [Read more...]

Troubleshooting ESD in Floating Medical Grade Circuits
Introduction Medical devices must be designed with proper isolation of patients from earth. For that reason all medical products have floating circuits. This means that the circuit ground is isolated from the earth ground. ESD protection in floating circuits with isolated grounds can be very challenging. Sometimes conventional ESD protection methods may not work. It is … [Read more...]
