Model: KS1GMD-US 4.3 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 -6dBV means the emission is 6dBV below the maximum limit. The equation for margin calculation is as follows: Margin = Corr. Ampl. – FCC Part 15C Limit 4.4 Environmental Conditions Temperature: 24 C Relative Humidity: 60  ATM Pressure: 1012 mbar 4.5 Summary of Test Results/Plots According to the data below, the FCC Part 15.205, 15.209 and 15.249 standards, and had the worst margin of: -16.81 dB at 945.4399 MHz in the Vertical polarization, Middle Channel, 9 kHz to 25 GHz, 3Meters Note: this EUT was tested in 3 orthogonal positions and the worst case position data was reported.

Model: KS1GMD-US 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 Procedure According to the ANSI 63.10-2013, 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. 6.3 Environmental Conditions Temperature: 25 C Relative Humidity: 53 ATM Pressure: 1018 mbar 6.4 Summary of Test Results/Plots Test Channel 20 dB Bandwidth 99% Bandwidth Channel MHz kHz kHz Low Channel 2408 2085 2192.4 Middle Channel 2440 2091 2136.4 High Channel 2474 2091 2153.4 Please refer to the following test plots Report No.: STR18018296I Page 23 of 25 FCC Part 15.249
