(Kunshan) Report No.: RSHA190626002-00B FCC 15.207 (a) AC LINE CONDUCTED EMISSIONS Applicable Standard FCC15.207 EUT Setup The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The specification used was with the FCC Part 15.207 limits. EMI Test Receiver Setup The EMI test receiver was set to investigate the spectrum from 150 kHz to 30 MHz. During the conducted emission test, the EMI test receiver was set with the following configurations:
Frequency Range 150 kHz 30 MHz IF B/W 9 kHz Test Procedure Maximizing procedure was performed on the six (6) highest emissions of the EUT. All data was recorded in the Quasi-peak and average detection mode. FCC Part 15.249 Page 10 of 16 Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190626002-00B Corrected Factor & Over Limit Calculation The Corrected factor is calculated by adding LISN VDF (Voltage Division Factor), Cable Loss and Transient Limiter Attenuation. The basic equation is as follows:
Factor (dB) = LISN VDF (dB) + Cable Loss (dB) + Transient Limiter Attenuation (dB) The Over Limit column of the following data tables indicates the degree of compliance with the applicable limit. For example, an Over Limit of 7dB means the emission is 7 dB above the limit. The equation for Over Limit calculation is as follows:
Over Limit (dB) = Read level (dBV) + Factor (dB) - Limit (dBV) Test Results Summary According to the recorded data in following table, the EUT complied with the FCC Part 15.207. Test Data Environmental Conditions Temperature:

(Kunshan) Report No.: RSHA190626002-00B FCC15.205, 15.209&15.249- RADIATED EMISSIONS& OUT OF BAND EMISSION Applicable Standard As per FCC15.249 (a), except as provided in paragraph (b) of this section, the field strength of emissions from intentional radiators operated within these frequency bands shall comply with the following:
Fundamental frequency Field strength of fundamental
(millivolts/meter) Field strength of harmonics
(microvolts/meter) 902928 MHz 24002483.5 MHz 57255875 MHz 50 50 50 500 500 500 As per FCC15.249 (c), Field strength limits are specified at a distance of 3 meters.
(d) Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in 15.209, whichever is the lesser attenuation. EUT Setup Below 1 GHz:
The radiated emission and out of band emission tests were performed in the 3 meters chamber test site, using the setup accordance with the ANSI C63.10-2013. The specification used was the FCC 15.209/15.205 and FCC 15.249 limits. The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle. FCC Part 15.249 Page 14 of 16 Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190626002-00B Test Equipment Setup The system was investigated from 30 MHz to 1 GHz. During the radiated emission test, the EMI test receiver Setup was set with the following configurations:
Frequency Range RBW Video B/W 30 MHz 1000 MHz 120 kHz 300 kHz IF B/W 120 kHz Detector QP Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. Data was recorded in Quasi-peak detection mode for frequency range of 30 MHz-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 (dBV /m) = Meter Reading (dBV) + Antenna Factor (dB/m) + Cable Loss
(dB) - Amplifier Gain (dB) The Margin column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of 7dB means the emission is 7dB below the limit. The equation for margin calculation is as follows:
Margin (dB) = Limit (dBV/m) Corrected Amplitude (dBV /m) Test Results Summary According to the data in the following table, the EUT complied with the FCC Part 15.209 &15.205 &
