4.2 Test Mode
To investigate the maximum EMI emission characteristics generates from EUT, the test system was pre-
scanning tested base on the consideration of following EUT operation mode or test configuration mode
which possible have effect on EMI emission level. Each of these EUT operation mode or test configuration
mode mentioned above was evaluated respectively.

7.4 Test Procedure
1. The testing follows the guidelines in Spurious Radiated Emissions of ANSI C63.10-2013.

2. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground plane. And above
    1000MHz, The EUT was placed on a styrofoam table which is 1.5m above ground plane.

3. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a
    variable height antenna tower.

4. For each suspected emission, the EUT was arranged to its worst case and then tune the Antenna tower
    (From 1m to 4m) and turntable (from 0 degree to 360 degree) to find the maximum reading. A pre-amp
    and a high pass filter are used for the test in order to get better signal level to comply with the guidelines.

5. Set to the maximum power setting and enable the EUT transmit continuously.

6. Final measurement (Above 1GHz): The frequency range will be divided into different sub ranges
    depending of the frequency range of the used horn antenna. The EMI Receiver set to peak and average
    mode and a resolution bandwidth of 1MHz. The measurement will be performed in horizontal and vertical
    polarization of the measuring antenna and while rotating the EUT in its vertical axis in the range of 0
    degree to 360 degree in order to have the antenna inside the cone of radiation.

7. Test Procedure of measurement (For Above 1GHz):

1) Monitor the frequency range at horizontal polarization and move the antenna over all sides of the EUT(if
    necessary move the EUT to another orthogonal axis).

2) Change the antenna polarization and repeat 1) with vertical polarization.

3) Make a hardcopy of the spectrum.

4) Measure the frequency of the detected emissions with a lower span and resolution bandwidth to increase
    the accuracy and note the frequency value.

5) Change the analyser mode to Clear/ Write and found the cone of emission.

6) Rotate and move the EUT, so that the measuring distance can be enlarged to 3m and the antenna will be
    still inside the cone of emission.

7) Measure the level of the detected frequency with the correct resolution bandwidth, with the antenna
    polarization and azimuth and the peak and average detector, which causes the maximum emission.

8) Repeat steps 1) to 7) for the next antenna spot if the EUT is larger than the antenna beamwidth.

7. The radiation measurements are tested under 3-axes(X,Y,Z) position(X denotes lying on the table, Y
denotes side stand and Z denotes vertical stand), After pre-test, It was found that the worse radiation
emission was get at the X position. So the data shown was the X position only.

    8.1 Block Diagram of Test Setup




    8.2 Rules and specifications
        DFR 47 Part 15.215(c)
        ANSI C63.10-2013

    8.3 Test Procedure
        Intentional radiator operating under the altemative provisions to the general emission
        limits,as contained in 15.217 and in subpart E of this part,must be designed to ensure
        that 20dB bandwidth of the emission, or whatever bandwidth may otherwise be
        specified in the specific rule section under which the equip compliance with the 20dB
        attenuation specification may base on measurement at the intentional radiator’s
        antenna output terminal unless the intentional radiator uses a permanently attached
        antenna, in which case compliance shall be deomonstrated by measuring the radiated
        emissions.

    8.4 Result
        Pass.

9     Antenna Requirement


    9.1 Regulation

          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.


    9.2 Result

          -Complied

          The transmitter has permanently attached Loop Coil antenna (internal antenna) on board.
