Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RXM171115050-00A 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.
