Report No.: NTC1706408FV00 FCC ID: 2AAXFHD160108 (2) Radiated Emission Test Set-Up, Frequency above 1GHz 3m Turntable 4m EUT Spectrum 1.5m Amplifier Analyzer 2.2 Measurement Procedure a. Blow 1GHz, the EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter semi- anechoic chamber room. Above 1GHz, the EUT was placed on the top of a rotating table 1.5 meters above the ground at a 3 meter full anechoic chamber room. The table was rotated 360 degrees to determine the position of the highest radiation. b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. c. The height of antenna 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 are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. The test-receiver system was set to peak detect function and specified bandwidth with maximum hold mode. e. A Quasi-peak measurement was then made for that frequency point for below 1GHz test. PK and AV for above 1GHz emission test. For 30MHz to 1GHz: Sept the spectrum analyzer as: RBW=120kHz, VBW=300kHz, Detector=Quasi-Peak For Above 1GHz: Set the spectrum analyzer as: RBW=1MHz, VBW=3MHz, Detector=Peak. Set the spectrum analyzer as: RBW=1MHz, VBW=10Hz, Detector=Peak. Page 7 of 19
