In this application note we address the generation of RF fields in the 1 to 6 GHz frequency range, looking to conventional methods of field generation and Raditeq cutting edge technology in field generation with the RadiField Triple A. According the RF immunity standard EN-61000-4-3, a uniform field must be generated at a distance of three meters from the tip of the antenna in this so called homogeneous area or quite zone. The Device Under Test (DUT) is tested with respect to its immunity to the applied uniform field. The area of uniform, illumination is 1.5 * 1.5 meters, to ensure that also 1 meter of cable to the DUT is in the field. The field is considered to be uniform when 75% of 12 points in this area comply with the 0 to +6dB rule. In RF immunity systems using traditional design techniques the designer has to analyze a large number of individual specifications of the system components that are taken into consideration for integration into the test system. This application note explains how Raditeq has simplified the configuration of RF immunity test systems compared to the conventional designs.
