Report No.: DL-20231218049E 3.2.2 TEST PROCEDURE Below 1GHz test procedure as below: a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter semi-anechoic camber. 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 antenna height 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 (for the test frequency of below 30MHz, the antenna was tuned to heights 1 meter) and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10dB margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet. Above 1GHz test procedure as below: g. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter semi-anechoic camber. ( Above 18GHz the distance is 3 meter and table is 1.5 metre). h. Test the EUT in the lowest channel ,the middle channel ,the Highest channel Note: Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis.

(2) The tighter limit applies at the band edges. (3) Emission level (dBuV/m)=20log Emission level (uV/m). Spectrum Parameter Attenuation Start Frequency Stop Frequency RB / VB (emission in restricted band) Setting Auto 2300MHz 2520MHz 1 MHz / 1 MHz for Peak, 1 MHz / 10Hz for Average 3.3.2 TEST PROCEDURE Above 1GHz test procedure as below: a. 1. The EUT was placed on the top of a rotating table 1.5 meters above the ground at a 3 meter camber. 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 antenna height 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 rota table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10dB margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet. g. Test the EUT in the lowest channel,the Highest channel Note: Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis. The worst case emissions were reported 3.3.3 DEVIATION FROM TEST STANDARD No deviation Test Report Tel: 400-688-3552 Web:www.dl-cert.com Email: [email protected] Page 20 of 35 Shenzhen DL Testing Technology Co., Ltd. 3.3.4 TEST SETUP Radiated Emission Test-Up Frequency Above 1GHz Aechoic 3m Chamber Antenna Elevation Varies From 1 to 4 m Turn Table From 0°to 360° 3m EUT 1.5m Turn Table Absorbers Report No.: DL-20231218049E PC System Spectrum Analyzer AMP Combining Network 3.3.5 EUT OPERATING CONDITIONS The EUT tested system was configured as the statements of 2.3 Unless otherwise a special operating condition is specified in the follows during the testing.
