3.2. Configuration and Methods of Measurements for Conducted Emissions
EN 55022 specifies the general configuration of the EUT and associated equipment, as well as the test
platform for conducted emissions testing.
Tabletop
devices are placed on a non-conducting surface 80
centimeters above the ground plane and 40 centimeters from a vertical ground plane wall. The EUT was
powered via an Artificial Mains Network (AMN). Both quasi-peak and average detector measurement modes
are used. If however, the average limit is met while using a quasi-peak detector, the test unit is deemed to
meet both the limits, and measurement with the average detector receiver is unnecessary. The quasi-peak and
average emission levels are then recorded and compared to the applicable EN 55022 limits to determine
compliance.
