※ Note: This test is not performed because the EUT is operated by DC battery.

     3.2 Purpose of the test
    - To determine whether the equipment under test fulfills the requirements of the standards stated in FCC Part 15
       Subpart C Section 15.247 and IC RSS-247
    3.3        Test Methodology
     Both conducted and radiated testing was performed according to the procedures in ANSI C63.10: 2013.
     Radiated testing was performed at a distance of 3 m from EUT to the antenna.

    3.4        Configuration of Test System
       3.4.1      Radiated emission test
     Preliminary radiated emissions test were conducted using the procedure in ANSI C63.10: 2013 to determine
     the worse operating conditions. Final radiated emission tests were conducted at 3 m Semi Anechoic Chamber.
     The turntable was rotated through 360 degrees and the EUT was tested by positioned three orthogonal planes
     to obtain the highest reading on the field strength meter. Once maximum reading was determined, the search
     antenna was raised and lowered in both vertical and horizontal polarization.

    3.5       Antenna requirement
    According to §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 shall be considered sufficient to comply with the provisions of this Section.
    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.
    And according to §15.247(b)(4), the conducted output power limit specified in paragraph (b) of this section is
    based on the use of antennas with directional gains that do not exceed 6 dBi.
    Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi
    are used, the conducted output power from the intentional radiator shall be reduced below the stated values in
    paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional
    gain of the antenna exceeds 6 dBi.

      3.5.1     Result: Pass
    The transmitter has a PCB Pattern antenna. The directional gain of the antenna is -2.96 ㏈i.

    6.3     Test setup
  The maximum peak output power was measured with the spectrum analyzer connected to the antenna output of
  the EUT. The spectrum analyzer’s internal channel power integration function is used to integrate the power over
  a bandwidth greater than or equal to the 99 % bandwidth. The EUT was operating in transmit mode at the
  appropriate center frequency.
  And e.i.r.p. is added antenna maximum gain with the Maximum Conducted Output Power.

    9.3     Test setup
  The radiated emissions measurements were performed on the 3 m, Semi-Anechoic Camber. The EUT was placed
  on a non-conductive turntable above the ground plane.

  The frequency spectrum from 9 ㎑ to 26.5 ㎓ was scanned and maximum emission levels at each frequency
  recorded. The system was rotated 360°, and the antenna was varied in the height between 1.0 m and 4.0 m in
  order to determine the maximum emission levels. This procedure was performed for horizontal and vertical
  polarization of the receiving antenna.
