However, if the emissions fall within one of the restricted bands from 15.205 the field strength levels need to be under that of the limits in 15.209. Test procedures: The EUT was oriented as to produce the maximum emission levels. The resolution bandwidth was set to 100kHz and the EMI receiver was used to scan from the bandedge to the fundamental frequency with a quasi-peak detector. The highest emissions level beyond the bandedge was measured and recorded. All band edge measurements were evaluated to the general limits in Part 15.209. Measurements were performed as radiated measurements in the same manner as Section 3.1 of this report. Deviations from test standard: No deviation. Test setup: All the measurements were done at 3m test distance while an operator was trying to activate the hopping sequence manually. EUT operating conditions: The EUT was powered by 5 VDC unless specified and set to transmit continuously on the lowest frequency channel, and the highest frequency channel.

The lower limit shall apply at the transition frequencies. 2. The limit decreases in line with the logarithm of the frequency in the range of 0.15 to 0.50 MHz. 3. All emanations from a class A/B digital device or system, including any network of conductors and apparatus connected thereto, shall not exceed the level of field strengths specified above. Test Procedures: a. The EUT was placed 0.8m above a ground reference plane and 0.4 meters from the conducting wall of a shielded room with EUT being connected to the power mains through a line impedance stabilization network (LISN). The LISN provides 50 ohm/ 50uH of coupling impedance for the measuring instrument. b. Both lines of the power mains connected to the EUT were checked for maximum conducted interference as well as the ground. c. The frequency range from 150 kHz to 30 MHz was searched. Emission levels over 10dB under the prescribed limits are not reported. d. Results were compared to the 15.207 limits. Deviation from the test standard: No deviation EUT operating conditions: The EUT was powered by 5 VDC unless specified and set to transmit continuously on the middle channel.

0 Report Number: R20181015-20-02 Rev C Prepared for: Garmin Annex A - Sample Calculation Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF – (-CF + AG) + AV where FS = Field Strength RA = Receiver Amplitude AF = Antenna Factor CF = Cable Attenuation Factor AG = Amplifier Gain AV = Averaging Factor (if applicable) Assume a receiver reading of 55 dBV is obtained. The Antenna Factor of 12 and a Cable Factor of 1.1 is added. The Amplifier Gain of 20 dB is subtracted, giving a field strength of 48.1 dBV/m. FS = 55 + 12 – (-1.1 + 20) + 0 = 48.1 dBV/m The 48.1 dBV/m value can be mathematically converted to its corresponding level in V/m. Level in V/m = Common Antilogarithm [(48.1 dBV/m)/20]= 254.1 V/m AV is calculated by the taking the 20*log(Ton/100) where Ton is the maximum transmission time in any 100ms window.
