Test procedure below 30 1. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter anechoic chamber test site. The table was rotated 360 degrees to determine the position of the highest radiation. 2. Then antenna is a loop antenna is fixed at one meter above the ground to determine the maximum value of the field strength. Both parallel and perpendicular of the antenna are set to make the measurement. 3. For each suspected emission, the EUT was arranged to its worst case and then the table was turned from 0 degrees to 360 degrees to find the maximum reading. 4. The test-receiver system was set to average or quasi peak detect function and Specified Bandwidth with Maximum hold mode. Test procedure above 30 1. Spectrum analyzer settings for f < 1 ⑦ Span = wide enough to fully capture the emission being measured RBW = 100 VBW ≥ RBW Detector = Peak detection (PK) or Quasi-peak detection (QP) Sweep time = auto Trace = max hold 2. Spectrum analyzer settings for f ≥1 ⑦ Peak Analyzer center frequency was set to the frequency of the radiated spurious emission of interest RBW = 1 VBW ≥ 3 Detector = peak Sweep time = auto Trace = max hold Trace was allowed to stabilize This report shall not be reproduced except in full, without the written approval of KES Co., Ltd.
