41 8..2 Radiated Emission Test Set-Up, Frequency above GHz 3m Turntable 4m EUT.5m mplifier Spectrum nalyzer 8.2 Measurement Procedure a. Blow GHz, the EUT was placed on the top of a rotating table.8 meters above the ground at a 3 meter semi- anechoic chamber room. b. For the radiated emission test above GHz: The EUT was placed on the top of a rotating table.5 meters above the ground at a 3 meter full anechoic chamber room. The table was rotated 36 degrees to determine the position of the highest radiation. Place the measurement antenna away from each area of the EUT determined to be a source of emissions at the specified measurement distance, while keeping the measurement antenna aimed at the source of emissions at each frequency of significant emissions, with polarization oriented for maximum response. The measurement antenna may have to be higher or lower than the EUT, depending on the radiation pattern of the emission and staying aimed at the emission source for receiving the maximum signal. The final measurement antenna elevation shall be that which maximizes the emissions. The measurement antenna elevation for maximum emissions shall be restricted to a range of heights of from m to 4 m above the ground or reference ground plane. c. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. d. 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. e. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from meter to 4 meters and the rotatable table was turned from degrees to 36 degrees to find the maximum reading. The test-receiver system was set to peak detect function and specified bandwidth with maximum hold mode. f. Quasi-peak measurement was then made for that frequency point for below GHz test. PK and V for above GHz emission test. Page 4 of 47

(3) s shown in 5.35(b), for frequencies above MHz, the field strength limits are based on average detector, however, the peak field strength of any emission shall not exceed the maximum permitted average limits, specified above by more than 2dB under any condition of modulation. (4) The frequency range scanned is from the lowest radio frequency signal generated in the device which is greater than 9 khz to the tenth harmonic of the highest fundamental frequency or 4 GHz, whichever is lower. (5) 5.247(d) specifies that emissions which fall in the restricted bands, as defined in 5.25 comply with radiated emission limits specified in Measurement Results Please refer to following plots of the worst case (82.b Mid Channel) Page 42 of 47
