Acrox Technologies Co., Ltd. Model: KBG 4.4 Test Procedure The setup of EUT is according with per ANSI C63.4-2003 measurement procedure. The specification used was with the FCC Part 15.205 15.249(a) and FCC Part 15.209 Limit. 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. Frequency :9kHz-30MHz Frequency :30MHz-1GHz Frequency :Above 1GHz RBW=10KHz, RBW=120KHz, RBW=1MHz, VBW =30KHz VBW=300KHz VBW=3MHz(Peak), 10Hz(AV) Sweep time= Auto Sweep time= Auto Sweep time= Auto Trace = max hold Trace = max hold Trace = max hold Detector function = peak Detector function = peak, QP Detector function = peak, AV 4.5 Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows: Corr. Ampl. = Indicated Reading + Ant. Factor + Cable Loss – Ampl. Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of -6dBμV means the emission is 6dBμV below the maximum limit. The equation for margin calculation is as follows: Margin = Corr. Ampl. – FCC Part 15C Limit REPORT NO.: STR14108198I PAGE 9 OF 24 FCC PART 15.249

Acrox Technologies Co., Ltd. Model: KBG 6. Emission Bandwidth 6.1 Standard Applicable According to 15.215 (c), intentional radiators operating under the alternative provisions to the general emission limits, as contained in §§15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. The requirement to contain the designated bandwidth of the emission within the specified frequency band includes the effects from frequency sweeping, frequency hopping and other modulation techniques that may be employed as well as the frequency stability of the transmitter over expected variations in temperature and supply voltage. If a frequency stability is not specified in the regulations, it is recommended that the fundamental emission be kept within at least the central 80% of the permitted band in order to minimize the possibility of out-of-band operation. 6.2 Test Equipment List and Details Description Manufacturer Model Serial Number Cal. Date Due. Date Spectrum Analyzer Agilent E4402B US41192821 2014-05-28 2015-05-27 Attenuator ATTEN ATS100-4-20 / 2014-05-28 2015-05-27 6.3 Test Procedure According to the ANSI 63.4-2003, the emission bandwidth test method as follows. Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to the spectrum analyzer. Set span = 1MHz, centered on a transmitting channel RBW ≥1% 20dB Bandwidth, VBW ≥RBW Sweep = auto Detector function = peak Trace = max hold All the trace to stabilize, use the marker-to-peak function to set the marker to the peak of the emission, use the marker-delta function to measure and record the 20dB down and 99% bandwidth of the emission. 6.4 Environmental Conditions Temperature: 25 °C Relative Humidity: 53% ATM Pressure: 1018 mbar 6.5 Summary of Test Results/Plots REPORT NO.: STR14108198I PAGE 22 OF 24 FCC PART 15.249
