The distance between EUT and receive antenna should be 3 meters. During the test, the EUT was operating in its typical mode. The test method is according to ANSI C63.4-2014. Sweep the whole frequency band through the range from 30MHz to the 5th harmonic of the carrier. During the test, the height of receive antenna shall be moved from 1 to 4 meters, and the antenna shall be performed under horizontal and vertical polarization. The turn table shall be rotated from 0 to 360 degrees for detecting the maximum of radiated signal level. The data of cable loss and antenna factor has been calibrated in full testing frequency range before the testing. During the test, the EUT is worked at maximum output power. Set the spectrum analyzer in the following: Below 1GHz: RBW=100 kHz / VBW=300 kHz / Sweep=AUTO Above 1GHz: (a) PEAK: RBW=1MHz / VBW=3MHz/ Sweep=AUTO (b) AVERAGE: RBW=1MHz / VBW=3MHz / Sweep=AUTO The radiated emission was measured in the following position: EUT stand-up position (Z axis), lie-down position (X, Y axis). The worst emission was found in lie-down position (X axis) and the worst case was recorded. TA Technology (Shanghai) Co., Ltd.
