Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM181029052-00 Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. According to §15.231, Intentional radiators operating under the provisions of this Section shall demonstrate compliance with the limits on the field strength of emissions, based on the average value of the measured emissions. As an alternative, compliance with the limits in the above table may be based on the use of measurement instrumentation with a CISPR quasi-peak detector 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 7dB means the emission is 7dB 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 CFR47 §15.205, §15.209, §15.231 (e). Test Data Environmental Conditions Temperature: 26.3~26.5 C Relative Humidity: 35 % ATM Pressure: 99.7kPa The testing was performed by Vern Shen ,Tyler Pan on 2018-11-15.
