Report No.: DREFCC1904-0136 FCC ID : ZNFOJ1928 7. Test Results : Emission 7.1 Conducted Disturbance ANSI C63.4 Mains terminal disturbance voltage Result Method: The AMN placed 0,8 m from the boundary of the unit under test and bonded to a ground reference plane. This distance was between the closest points of the AMN and the EUT. All other units of the EUT and associated equipment were at least 0,8 m from the AMN. All power was connected to the system through Artificial Mains Network (AMN). Conducted voltage measurements on mains lines were made at the output of the AMN. The measuring port of the LISN for EUT was connected to spectrum analyzer. Using conducted emission test software, the emissions were scanned with peak detector mode. After scanning over the Comply frequency range, suspected emissions were selected to perform final measurement. When performing final measurement, the receiver was used which has Quasi-Peak detector and CISPR Average detector. For (0.15 ~ 30) MHz frequency range, Quasi-Peak detector with 10 kHz RBW and 30 kHz VBW was used. By varying the configuration of the test sample and the cable routing it was attempted to maximize the emission. Fully configured sample scanned ov Frequency range on each side of line Measurement Point er the following frequency range 150 kHz to 30 MHz Mains EUT mode Test configuration mode 1 (Refer to clauses 4) EUT Operation mode 1 Limits – Class A Limit dBµV Frequency (MHz) Quasi-Peak Average 0.15 to 0.50 79 66 0.50 to 30 73 60 Limits – Class B Limit dBµV Frequency (MHz) Quasi-Peak Average 0.15 to 0.50 66 to 56 56 to 46 0.50 to 5 56 46 5 to 30 60 50 Measurement Instrument Description Model Manufacturer Identifier Cal.

Report No.: DREFCC1904-0136 FCC ID : ZNFOJ1928 7.2 Radiated Disturbance ANSI C63.4 Radiated disturbance 30 MHz – 40 GHz Result Method: Preliminary (peak) measurements were performed at an antenna to EUT separation distance of 10 or 3 meter below 1GHz and 3 meter above 1GHz. The EUT was rotated 360° about its azimuth with the receive antenna located at various heights in horizontal and vertical polarities. Final measurements were then performed by rotating the EUT 360° and adjusting the receive antenna height from 1 to 4 m. All frequencies were investigated in both horizontal and vertical antenna polarity, Comply where applicable. For final measurement below 1 GHz frequency range, Quasi-Peak detector with (RBW = 120 kHz Bandwidth) was used. For final measurement above 1 GHz frequency range, Peak detector with (RBW = 1 MHz Bandwidth) and CISPR Average detector with (RBW = 1 MHz Bandwidth) were used.
