( Page 13 of 24 Report No.: GTI20180533F—2 7.2.Radiated Emission Limit For intentional device, according to§ 15.209(a), § 15.249(a), the general requirement of field strength of radiated emission from intentional radiators at a distance of 3 meters shall not exceed the following table. The frequency spectrum above 1 GHz for Transmitter was investigated. All emission not reported are much lower than the prescribed limits. Set the RBW=1MHz, VBW=3MHz for Peak Detector while the RBW=1MHz, VBW=10Hz for Average Detector, Readings are both peak and average values.

The EUT was placed on a turn table which is 0.8m(below 1GHz)or1.5m(above 1GHz) above ground plane. 6. Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating the turn table from 0°C to 360°C to acquire the highest emissions from EUT 7. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. 8. Repeat above procedures until all frequency measurements have been completed. Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CL — AG Where __FS = Field Strength CL = Cable Attenuation Factor (Cable Loss) RA = Reading Amplitude AG = Amplifier Gain AF = Antenna Factor For example Frequency FS RA AF CL AG Transd (MHz) (dBuV/m) (dBpuV/m) (dB) (dB) (dB) (dB) 150.00 40 58.1 12.2 1.6 31.90 —18.1 Transd=AF +CL—AG Test Configuration For the actual test configuration, please refer to the related Item —EUT Test Photos.

Page 19 of 24 Report No.: GTI20180533F-2 7.4. Band edge Test Test Limit For intentional device, according to§ 15.249(d), Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in 15.209, whichever is the lesser attenuation. Test Procedure The frequency spectrum above 1 GHz for Transmitter was investigated. All emission not reported are much lower than the prescribed limits. Set the RBW=1MHz, VBW=3MHz for Peak Detector while the RBW=1MHz, VBW=10Hz for Average Detector, Readings are both peak and average values. The pre-test have done for the EUT in three axes and found the worst emission at position shown in test setup photos. 1. The EUT was placed on a turn table which is 0.8m(below 1GHz)or1.5m(above 1GHz) above ground plane 2. . The table was rotated 360 degrees to determine the position of the highest radiation. 3. The EUT was set 3 meters away from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 4. The antenna 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 set to make the measurement. 5. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. 6. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. 7. Place a marker at the end of the restricted band closest to the transmit frequency to show compliance. Also measure any emissions in the restricted bands. Save the spectrum analyzer plot. Repeat for each power and modulation for lowest and highest channel 8. Test the EUT in the lowest channel, the highest channel 9. The radiation measurements are performed in X, Y, Z axis positioning. And found the X axis positioning which it is worse case, only the test worst case mode is recorded in the report. 10. Repeat above procedures until all frequencies measured was complete. Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CL – AG Where FS = Field Strength CL = Cable Attenuation Factor (Cable Loss) RA = Reading Amplitude AG = Amplifier Gain AF = Antenna Factor For example Frequency FS RA AF CL AG Transd (MHz) (dBμV/m) (dBμV/m) (dB) (dB) (dB) (dB) 150.00 40 58.1 12.2 1.6 31.90 -18.1 Transd=AF +CL-AG Test Configuration For the actual test configuration, please refer to the related Item –EUT Test Photos.

Page 21 of 24 Report No.: GTI20180533F-2 7.5. Antenna Requirement Standard Applicable For intentional device, according to FCC 47 CFR Section 15.203: An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited Result The EUT’s antenna used a Antenna, soldered on the PCB., The antenna’s gain is 4.17dBi. Complying with the standard requirement.
