Field Strength of Fundamental & Harmonics Emissions
Test Requirement: FCC 47CFR 15.249
Test Method: ANSI C63.10:2013
Test Date: 2018-08-03
Mode of Operation: 1. Tx Mode
#
Test Method:
For emission measurements at or below 1 GHz, the sample was placed 0.8m above the ground plane of semi-
anechoic Chamber*. For emission measurements above 1 GHz, the sample was placed 1.5m above the ground
plane of semi-anechoic 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 turntable, varying antenna height from 1m to 4m in both horizontal
and vertical polarizations. In the frequency range of 9kHz to 30MHz, The center of the loop antenna shall be 1
meter above the ground and rotated loop axis for maximum reading. The emissions worst-case are shown in Test
Results of the following pages.
Remark: 3 orthogonal axis apply to hand-held device only.
*:
Semi-anechoic chamber located on the G/F of The Hong Kong Standards and Testing Centre Ltd.
FCC Test Firm Registration Number 723883
Designation Number HK0001
# The Tx mode of the EUT was set to continuous transmit fixed at frequencies, 2408MHz, 2435MHz and
2467MHz during test.
