Let the EUT work in TX mode measure it. 4.5.Test Procedure The EUT and its simulators are placed on a turntable, which is 0.8 meter high above ground(Below 1GHz). The EUT and its simulators are placed on a turntable, which is 1.5 meter high above ground(Above 1GHz). The turntable can rotate 360 degrees to determine the position of the maximum emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4 meters to find out the maximum emission level. Broadband antenna (calibrated bi-log antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the antenna are set on measurement. In order to find the maximum emission levels, all of the EUT location must be manipulated according to ANSI C63.10:2013 on radiated emission measurement. This EUT was tested in 3 orthogonal positions and the worst case position data was reported. The bandwidth of test receiver is set at 120 kHz in 30-1000 MHz, and 1 MHz in 1000 MHz. 4.6.The Field Strength of Radiation Emission Measurement Results PASS. The frequency range from 30 MHz to 10GHz is checked. FCC ID: WA5WS69CN Shenzhen Accurate Technology Co., Ltd.

Peak or Quasi-Peak measurement. The measurements with active loop antenna were greater than 20dB below the limit, so the test data were not recorded in the test report. 2. Emissions attenuated more than 20 dB below the permissible value are not reported. 3. The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows: Result = Reading + Corrected Factor Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain 4. FCC Limit for Average Measurement = 16.67*(433.92) - 2833.33 = 4400.1164 V/m =72.87 dBV/m 5. The spectral diagrams in appendix I display the measurement of peak values. 6.

The EUT is tested radiation emission in three axes(X,Y,Z). The worst emissions are reported in three axes. 9. Pulse Desensitization Correction Factor Pulse Width (PW) = 13.6ms 2/PW = 2/13.6ms = 0.15kHz RBW (100kHz) > 2/PW (5kHz) Therefore PDCF is not needed.

AVERAGE FACTOR MEASUREMENT 7.1.Block Diagram of Test Setup Spectrum EUT Low Loss Cable Analyzer (EUT: Weather Station (Transmitter)) 7.2.Average factor Measurement according to ANSI C63.10-2013 ANSI C63.10-2013 Section 7.5 Unless otherwise specified, when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 s (100 ms). In cases where the pulse train exceeds 0.1 s, the measured field strength shall be determined during a 0.1 s interval.64 The following procedure is an example of how the average value may be determined. The average field strength may be found by measuring the peak pulse amplitude (in log equivalent units) and determining the duty cycle correction factor (in dB) associated with the pulse modulation as shown in Equation (10): Average factor in dB = 20 log (duty cycle) 7.3.EUT Configuration on Measurement The equipment are installed on average factor Measurement to meet the commission requirements and operating regulations in a manner which tends to maximize its emission characteristics in normal application. 7.4.
