2) 30 MHz to 1 GHz emissions:
3) 1 GHz to 40 GHz emissions:
ITL Page 11 of 24 Report No.: D190314003 Test Procedure:
1) 9 kHz to 30 MHz emissions:
For testing performed with the loop antenna. The centre of the loop was positioned 1 m above the ground and positioned with its plane vertical at the special distance from the EUT. During testing the loop was rotated about its vertical axis for maximum response at each azimuth and also investigated with the loop positioned in the horizontal plane. 2) 30 MHz to 1 GHz emissions:
For testing performed with the bi-log type antenna. The measurement is performed with the EUT rotated 360, the antenna height scanned between 1m and 4m, and the antenna rotated to repeat the measurement for both the horizontal and vertical antenna polarizations. 3) 1 GHz to 40 GHz emissions:
Test site with RF absorbing material covering the ground plane that met the site validation criterion called out in CISPR 16-1-4:2007 was used to perform radiated emission test above 1 GHz. For testing performed with the horn antenna. The measurement is performed with the EUT rotated 360, the antenna height scanned between 1m and 4m, and the antenna rotated to repeat the measurement for both the horizontal and vertical antenna polarizations. The field strength of radiation emission was measured in the following position: EUT stand-up position (Y axis), lie-down position (X, Z axis). The worst case of X axis was reported. Detector: Resolution bandwidth for Peak and Quasi-Peak value:
200 Hz for 9 kHz to 150 kHz 9 kHz for 150 kHz to 30 MHz 120 kHz for 30 MHz to 1GHz 1 MHz for above 1 GHz, VBW RBW Sweep = auto Detector function = peak Trace = max hold For AV value:
Average = Peak value + 20log (Duty cycle) ITL Page 12 of 24 Report No.: D190314003 The average correction factor is computed by analyzing the on time in one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds, therefore the average value of fundamental frequency is: Average = Peak value + 20log (Duty cycle), where the duty factor is calculated from following formula:
The duration of one cycle=47.8ms Effective period of the cycle =(1.4x5+0.4x12) ms=11.8ms DC=11.8/47.8=0.24686 or 24.686%
Therefore, the averaging factor is found by 201g0. 24686=-12.15

For intentional radiators, measurements of the variation of the input power or the radiated signal level of the fundamental frequency component of the emission, as appropriate, shall be performed with the supply voltage varied between 85% and 115% of the nominal rated supply voltage. Pre-Scan has been conducted to determine the worst-case mode from all possible combinations between available modulations, channels and antenna ports (if EUT with antenna diversity architecture). ITL Page 22 of 24 Report No.: D190314003 Test Configuration:
Test procedure:
1. The mains terminal disturbance voltage test was conducted in a shielded room. 2. The EUT was connected to AC power source through a LISN (Line Impedance Stabilization Network) which provides a 50/50H + 5 linear impedance. A multiple socket outlet strip was used to connect multiple power cables to a single LISN provided the rating of the LISN was not exceeded. 3. The tabletop EUT was placed upon a non-metallic table 0.8m above the ground reference plane. And for floor-standing arrangement, the EUT was placed on the horizontal ground reference plane, but separated from metallic contact with the ground reference plane by 0.1m of insulation. 4. The test was performed with a vertical ground reference plane. The rear of the EUT shall be 0,4 m from the vertical ground reference plane. The vertical ground reference plane was bonded to the horizontal ground reference plane. The LISN was placed 0,8 m from the boundary of the unit under test and bonded to a ground reference plane for LISNs mounted on top of the ground reference plane. This distance was between the closest points of the LISN 1 and the EUT.. ITL Page 23 of 24 Report No.: D190314003 Measurement Data An initial pre-scan was performed on the live and neutral lines with peak detector.
