Section(s) 11.8.1 DTS Bandwidth, Option 1 Limits of bandwidth measurements:
The 99% occupied bandwidth is displayed. The 6dB bandwidth of the signal must be greater than 500 kHz. Test procedures:
The EUT was connected to the spectrum analyzer directly with a low-loss shielded coaxial cable. The bandwidth of the fundamental frequency was measured by spectrum analyzer with 100 kHz RBW and 300 kHz VBW. The 99% occupied is defined as the bandwidth at which 99% of the signal power is found. This corresponds to 20dB down from the maximum power level. The maximum power was measured with the largest resolution bandwidth possible (10MHz) and this value was recorded. The signal was then captured with a 1 MHz resolution bandwidth and the frequencies where the measurements were 20dB below the maximum power were marked. The bandwidth between these frequencies was recorded as the 99% occupied bandwidth. The 6 dB bandwidth is defined as the bandwidth of which is higher than peak power minus 6dB. For peak output power measurements, the EUT was connected to the spectrum analyzer directly with a low-loss shielded coaxial cable with 3 MHz RBW and 10 MHz VBW. Deviations from test standard:
No deviation Test setup:

In addition to the limits shown above, all emissions were also required to be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power. All measurements were performed with a 1 MHz bandwidth, but the bandwidth conversion from 1 MHz to 100 kHz would be equally applied to the highest emission and the spurious emissions, so it would not affect the delta measurement. Since the fundamental emissions was at least 20 dB over the spurious emissions limits from 15.209 and all spurious emissions were below the 15.209 limit, this requirement was met. NOTE:
1. The lower limit shall apply at the transition frequencies. 2. Emission level (dBuV/m) = 20 * log * Emission level (V/m). 3. As shown in 15.35(b), for frequencies above 1000MHz, the field strength limits are based on average detector, however, the peak field strength of any emission shall not exceed the maximum permitted average limits by more than 20dB under any condition of modulation.

Rev B a. The EUT was placed on the top of a rotating table above the ground plane in a 10 meter semi-
anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation. The table was 0.8m high for measurements form 30MHz-1Ghz and 1.5m for measurements from 1GHz and higher. b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. c. The antenna was a broadband antenna, and its height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are used to make the measurement. d. For each suspected emission, the EUT was arranged to maximize its emissions and then the antenna height was varied from 1 meter to 4 meters and the rotating table was turned from 0 degrees to 360 degrees to find the maximum emission reading. e. The test-receiver system was set to use a peak detector with a specified resolution bandwidth. For spectrum analyzer measurements, the composite maximum of several analyzer sweeps was used for final measurements. f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10 dB margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet. All 802.11 modes were examined (b, g, n, HT20) and it was found the 802.11n mode produced the highest emissions. All final measurements were performed with the EUT transmitting continuously in this mode.

Rev B 1. Section 6.10.5 (used for restricted bands) 2. Section 11.13.2 Marker-delta method (for unrestricted bands) 3. Section 11.11, Measurement in unrestricted frequency bands Limits of band edge measurements:
For emissions outside of the allowed band of operation (2400.0MHz 2480.0MHz), the emission level needs to be 20dB under the maximum fundamental field strength. 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 tested in the same method as described in section 4.4 - Bandwidth. The resolution bandwidth was set to 100 kHz and video bandwidth to 300 kHz the EMI receiver was used to scan from the band edge to the fundamental frequency with a quasi-peak detector. The highest emissions level beyond the band edge was measured and recorded. All band edge measurements were evaluated to the general limits in Part 15.209. Deviations from test standard:

(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 Assume a receiver reading of 55 dBV 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 dBV/m. FS = 55 + 12 (-1.1 + 20) + 0 = 48.1 dBV/m The 48.1 dBV/m value can be mathematically converted to its corresponding level in V/m. Level in V/m = Common Antilogarithm [(48.1 dBV/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. AV = Averaging Factor (if applicable) The Nebraska Center for Excellence in Electronics 4740 Discovery Drive Lincoln, NE 68521 Page 62 of 65 Report Number: R20190221-21 Prepared for: Garmin EIRP Calculations Rev B In cases where direct antenna port measurement is not possible or would be inaccurate, output power is measured in EIRP. The maximum field strength is measured at a specified distance and the EIRP is calculated using the following equation;
EIRP (Watts) = [Field Strength (V/m) x antenna distance (m)]2 / 30 Power (watts) = 10^[Power (dBm)/10] / 1000 Voltage (dBV) = Power (dBm) + 107 (for 50 measurement systems) Field Strength (V/m) = 10^[Field Strength (dBV/m) / 20] / 10^6 Gain = 1 (numeric gain for isotropic radiator) Conversion from 3m field strength to EIRP (d=3):
EIRP = [FS(V/m) x d^2]/30 = FS [0.3] for d = 3 EIRP(dBm) = FS(dBV/m) 10(log 10^9)+ 10log[0.3] = FS(dBV/m) - 95.23 10log( 10^9) is the conversion from micro to milli The Nebraska Center for Excellence in Electronics 4740 Discovery Drive Lincoln, NE 68521 Page 63 of 65 Report Number: R20190221-21 Prepared for: Garmin Rev B APPENDIX B MEASUREMENT UNCERT AINTY Where relevant, the following measurement uncertainty levels have been for tests performed in this test report:
