Scientific Toys Ltd. Model Number(s)/Catalog Number(s): 21882 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 -6dBV means the emission is 6dBV below the maximum limit for Part 15 of the FCC Rules. The equation for margin calculation is as follows: Margin = Corr. Ampl. – Limit of Part 15 of the FCC Rules 4.6 Environmental Conditions Temperature: 26 C Relative Humidity: 52 ATM Pressure: 1012 mbar 4.7 Summary of Test Results/Plots According to the data below, the standards of Part 15.249, 15.205 and 15.209 of the FCC Rules, and had the worst margin of: Note: This EUT was tested in 3 orthogonal positions and the worst case position data was reported.

Scientific Toys Ltd. Model Number(s)/Catalog Number(s): 21882 6. Emission Bandwidth 6.1 Standard Applicable According to Part 15.215 (c) of the FCC Rules, 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 Serial Description Manufacturer Model Cal.

Set span = 1 MHz, centered on a transmitting channel RBW 1% 20 dB 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 REPORT NUMBER: GKK201406240A PAGE 22 OF 24 PART 15.249 OF THE FCC RULES
