Shanghai DareGlobal Technologies Co.,Ltd. FCC ID: RS3DSL-500 §15.109 - RADIATED EMISSIONS TEST Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency interpolation, measurement distance variation, site imperfections, mismatch (average), and system repeatability. Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of a radiation emissions measurement at Bay Area Compliance Lab Corp. (ShenZhen) is +4.4 dB. The fundamental data was recorded in average detection mode: set the VBW AVE on, and then record the data. EUT Setup The radiated emission tests were performed in the 3 meters chamber A test site, using the setup accordance with the ANSI C63.4-2003. The specification used was the FCC Part 15 Class B limits. EMI Test Receiver Setup The system was investigated from 30 MHz to 1000 MHz.

(ShenZhen) attests that all calibrations have been performed per the NVLAP requirements, traceable to NIST. Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Loss and Cable Loss, and subtracting the Amplifier Gain from the Meter reading. The basic equation is as follows: Corr. Ampl. = Meter Reading + Antenna Loss+ 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 maximum limit. The equation for margin calculation is as follows: Margin = Corr. Ampl. - Limit Test Results Summary According to the data in the following table, the EUT complied with the FCC Part 15 Class B, with the worst margin reading of: -0.9 dB at 251.18 MHz in the Horizontal polarization.
