Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190125002-00A Corrected Factor & Margin Calculation The Corrected factor is calculated by adding LISN/ISN VDF (Voltage Division Factor), Cable Loss and Transient Limiter Attenuation. The basic equation is as follows: Correction Factor = LISN VDF + Cable Loss + Transient Limiter Attenuation The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of 7 dB means the emission is 7 dB below the limit. The equation for margin calculation is as follows: Margin = Limit – Corrected Amplitude Test Results Summary According to the recorded data in following table, the EUT complied with the FCC Part 15.107, Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level is in compliance with the limit if Lm + U(Lm) ≤ Llim + Ucispr In BACL., U(Lm) is less than Ucispr, if Lm is less than Llim, it implies that the EUT complies with the limit.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190125002-00A The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle. The spacing between the peripherals was 10 cm. EMI Test Receiver Setup The system was investigated from 30 MHz to 13.5 GHz. During the radiated emission test, the EMI test receiver was set with the following configurations: Frequency Range RBW Video B/W IF B/W Measurment 30 MHz – 1000 MHz 100 kHz 300 kHz 120 kHz QP 1MHz 3 MHz / PK Above 1 GHz 1MHz 10 Hz / Ave. Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. All data was recorded in the Quasi-peak detector mode from 30 MHz to 1 GHz and PK and average detector modes for frequencies above 1 GHz. Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain from the Meter Reading. The basic equation is as follows: Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of 7 dB means the emission is 7 dB below the limit. The equation for margin calculation is as follows: Margin = Limit – Corrected Amplitude Test Results Summary According to the data in the following table, the EUT complied with the FCC §15.109 Class B, Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level is in compliance with the limit if Lm + U(Lm) ≤ Llim + Ucispr In BACL, U(Lm) is less than Ucispr, if Lm is less than Llim, it implies that the EUT complies with the limit.
