Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190123004-00A

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.: RSZ190123004-00A

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.
