The EUT was placed on the top of a rotating table (0.8m for below 1G and 1.5m for above 1G) above the ground at a 3 meter camber. The table was rotated 360 degrees to determine the position of the highest radiation. . The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. . The antenna height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna Shenzhen QC Testing Laboratory Co., Ltd.
