Radiated Spurious Emission 11.1 Measurement Limits  15.209(a) Limit in the below table has to be followed Frequencies (MHz) Field Strength (microvolts/meter) Measurement Distance (meters) 0.009~0.490 2400/F(kHz) 300 0.490~1.705 24000/F(kHz) 30 1.705~30.0 30 30 30~88 100 3 88~216 150 3 216~960 200 3 Above 960 500 3 Note: All modes were tested for restricted band radiated emission, the test records reported below are the worst result compared to other modes. 11.2 Measurement Procedure 1. The EUT was placed on the top of the turntable 0.8 or 1.5 meter above ground. The phase center of the receiving antenna mounted on the top of a height-variable antenna tower was placed 3 meters far away from the turntable. 2. Power on the EUT and all the supporting units. The turntable was rotated by 360 degrees to determine the position of the highest radiation. 3. The height of the broadband receiving antenna was varied between one meter and four meters above ground to find the maximum emissions field strength of both horizontal and vertical polarization. 4. For each suspected emission, the antenna tower was scan (from 1 M to 4 M) and then the turntable was rotated (from 0 degree to 360 degrees) to find the maximum reading. 5. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function with specified bandwidth under Maximum Hold Mode. 6. For emissions above 1GHz, insert the 2.4G filter between the receiving antenna and the Pre-amplifier(only for Radiated Spurious Emission). Use 1MHz RBW and 3MHz VBW for peak reading. 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 1 m to 4 m above the ground or reference ground plane. 7. When the radiated emissions limits are expressed in terms of the average value of the emissions, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds. Report No.: AGC02931251206FR01 Page 65 of 95 As an alternative (provided the transmitter operates for longer than 0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field strength shall be determined from the average absolute voltage during a 0.1 second interval during which the field strength is at its maximum values. 8. If the emissions level of the EUT in peak mode was 3 dB lower than the average limit specified, then testing will be stopped and peak values of EUT will be reported, otherwise, the emissions which do not have 3 dB margin will be repeated one by one using the quasi-peak method for below 1GHz. 9. For testing above 1GHz, the emissions level of the EUT in peak mode was lower than average limit (that means the emissions level in peak mode also complies with the limit in average mode), then testing will be stopped and peak values of EUT will be reported, otherwise, the emissions will be measured in average mode again and reported. 10. In case the emission is lower than 30MHz, loop antenna has to be used for measurement and the recorded data should be QP measured by receiver. High - Low scan is not required in this case.  The following table is the setting of spectrum analyzer and receiver. Spectrum Parameter Setting Start ~Stop Frequency 9kHz~150KHz/RB 200Hz for QP Start ~Stop Frequency 150kHz~30MHz/RB 9kHz for QP Start ~Stop Frequency 30MHz~1000MHz/RB 120kHz for QP Start ~Stop Frequency 1GHz~26.5GHz 1MHz/3MHz for Peak, 1MHz/3MHz for Average Receiver Parameter Setting Start ~Stop Frequency 9kHz~150KHz/RB 200Hz for QP Start ~Stop Frequency 150kHz~30MHz/RB 9kHz for QP Start ~Stop Frequency 30MHz~1000MHz/RB 120kHz for QP Report No.: AGC02931251206FR01 Page 66 of 95  Quasi-Peak Measurements below 1GHz 1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest 2. Span was set greater than 1MHz 3. RBW = as shown in the table above 4. Detector = CISPR quasi-peak 5. Sweep time = auto couple 6. Trace was allowed to stabilize  Peak Measurements above 1GHz 1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest 2. RBW = 1MHz 3. VBW = 3MHz 4. Detector = peak 5. Sweep time = auto couple 6. Trace mode = max hold 7. Trace was allowed to stabilize  Average Measurements above 1GHz 1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest 2. RBW = 1MHz 3. VBW ≥ [3 × RBW] 4. Detector = Power averaging (rms) 5. Averaging type = power (i.e., rms) 6. Sweep time = auto 7. Perform a trace average of at least 100 traces. 8. The applicable correction factor is [10*log (1 / D)], where D is the duty cycle. The factor had been edited in the “Input Correction” of the Spectrum Analyzer.
