   3.3     Applicable Standard
     Intentional radiators operating under the alternative provisions to the general emission limits, as
     contained in §15.239, 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.

   3.4     Test Procedure
     1. Check the calibration of the measuring instrument using either an internal calibrator or a known
           signal from an external generator.
     2. Position the EUT on the test table without connection to measurement instrument. Turn on the
           EUT. Then set it to any one convenient frequency within its operating range. Set a reference level
           on the measuring instrument equal to the highest peak value.
     3. Measure the frequency difference of two frequencies that were attenuated 20dB bandwidth and 99%
           bandwidth from the reference level. Record the frequency difference as the emission bandwidth.
     4. Repeat above procedures until all frequencies measured were complete.

  5.3.4 Limit for this EUT

   The radiated emission tests were performed in the 3 meters test site, using the setup accordance with
   the ANSI C63.4:2014. The specification used was the FCC 15.209.

   5.4    Test Procedure
  (1) EUT was placed on a non-metallic table, 80 cm above the ground plane inside a semi-anechoic chamber.
  (2) Setup EUT and assistant system according clause 2.4 and 8.2
  (3) Test antenna was located 3m from the EUT on an adjustable mast. Below pre-scan procedure was first
      performed in order to find prominent radiated emissions.
      (a) Change work frequency or channel of device if practicable.
      (b) Change modulation type of device if practicable.
      (c) Change power supply range from 85% to 115% of the rated supply voltage
      (d) Rotated EUT though three orthogonal axes to determine the attitude of EUT arrangement produces
          highest emissions
  (4) Spectrum frequency from 9KHz to 25GHz (tenth harmonic of fundamental frequency) was investigated,
      and no any obvious emission were detected from 9KHz to 30MHz and 18GHz to 25GHz, so below final
      test was performed with frequency range from 30MHz to 18GHz.
  (5) For final emissions measurements at each frequency of interest, the EUT were rotated and the antenna
      height was varied between 1m and 4m in order to maximize the emission. Measurements in both
      horizontal and vertical polarities were made and the data was recorded. In order to find the maximum
      emission, the relative positions of equipments and all of the interface cables were changed according to
      ANSI C63.10 2013 on Radiated Emission test.
  (6) For emissions from 30MHz to 1GHz, Quasi-Peak values were measured with EMI Receiver and the
      bandwidth of Receiver is 120 KHz.



   5.5    Test result
   PASS. (See below detailed test result)
  According to the recorded data in following table, the EUT complied with the FCC Title 47, Part 15, Subpart C,
  and section 15.205, 15.209 and 15.239, Vertical and Horizontal mode all have been tested, Horizontal mode
  is the worse case(new battery is used during all test) .with the worst margin reading of:
