The sample was placed 0.8m & 1.5m for the measurement below & above 1GHz above the ground plane of 3m
chamber. Measurements in both horizontal and vertical polarities were performed. During the test, each emission
was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3
axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting
cables, rotating the turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations.
The emissions worst-case are shown in Test Results of the following pages.
