YMAX Communications Corp. FCC ID: Y79K1103 5 - FCC §15.109 Radiated Emission Test 5.1 Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in the field of EMI. The factors contributing to uncertainties are EMI Test Receiver, 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 EMI Measurements, the best estimate of the uncertainty of a radiation emissions measurement at BACL is +4.0 dB. 5.2 EUT Setup The radiated emission tests are performed at BACL, using the setup in accordance with the ANSI C63.4-2003. The specification used is the FCC Part 15 Class B limits. The excess cables shall be folded at the cable center into a bundle no longer than 40 cm. The separation between the neighbouring unit & EUT is 10 cm in the horizontal. DC 5V power source was provided to EUT through AC adaptor.

YMAX Communications Corp. FCC ID: Y79K1103 5.3 EMI Test Receiver Setup The system was investigated from 30 MHz to 1 GHz During the radiated emission test, the EMI test receiver is set with the following configurations: Frequency Range RBW Video B/W Detector 30 MHz – 1000 MHz 120 kHz 300 kHz QP 5.4 Test Procedure Maximizing procedure was performed on the six (6) highest emissions to ensure EUT is compliant with all installation combinations. All data were recorded in the quasi-peak detection mode. The EUT was in the normal operating mode during the final qualification test to represent the worst case results. 5.5 Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows: Corr. Ampl. = Indicated Reading + Antenna Factor + Cable Factor - 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 7 dBμV/m below the maximum limit for FCC Part 15 Class B. The equation for margin calculation is as follows: Margin = FCC Part 15 Class B Limit – Corr.
