EMC Radiated Emission Measurements at 1/3/5/10/30 Meters
INTRODUCTION There are two principal types of emission measurements in the world of electromagnetic compatibility, conducted emission and radiated emission. The conducted emission measurements are either a voltage-capacitive tap type of measurement (typically on a power line) or they are a current-clamp type of measurement (typically on a signal line).Radiated emission … [Read more...]
