    2 MEASUREMENT UNCERTAINTY
    Where relevant, the following measurement uncertainty levels have been estimated for
    tests performed on the EUT as specified in CISPR 16-4-2:

                    MEASUREMENT                               FREQUENCY                           UNCERTAINTY
                  Conducted emissions                          9kHz~30MHz                                2.70dB
                                                             9KHz ~ 30MHz                                2.16dB
                   Radiated emissions
                                                            30MHz ~ 1GMHz                                3.76dB


    This uncertainty represents an expanded uncertainty expressed at approximately the 95%
    confidence level using a coverage factor of k=2.

                    Test Report No.: RF190103N022

    4.1.3 TEST PROCEDURE

    a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with
       EUT being connected to the power mains through a line impedance stabilization
       network (LISN). Other support units were connected to the power mains through
       another LISN. The two LISNs provide 50 Ohm/ 50uH of coupling impedance for the
       measuring instrument.

    b. Both lines of the power mains connected to the EUT were checked for maximum
       conducted interference.

    c. The frequency range from 150 kHz to 30 MHz was searched. Emission levels under
       (Limit – 20dB) were not recorded.

     NOTE:

     1. Q.P. and AV. are abbreviations of quasi-peak and average individually.
     2. "-": The Quasi-peak reading value also meets average limit and
        measurement with the average detector is unnecessary.
     3. Margin value = Emission level - Limit value
     4. Correction factor = Insertion loss + Cable loss
     5. Emission Level = Correction Factor + Reading Value



    4.1.4 DEVIATION FROM TEST STANDARD

    No deviation.

           NOTE:
         1. The lower limit shall apply at the transition frequencies.
         2. Emission level (dBuV/m) = 20 log Emission level (uV/m).
         3. As shown in 15.35(b), for frequencies above 1000MHz, the field strength limits are based on average
             detector, however, the peak field strength of any emission shall not exceed the maximum permitted
             average limits, specified above by more than 20dB under any condition of modulation.
         4. The measured field strength was extrapolated to distance 30 meters, using the formula that the limit of
            field strength varies as the inverse distance square (40dB per decade of distance)
             Example:
             13.56MHz = 15848uV/m                       30m
                          = 84dBuV/m                    30m
                          = 84+20log(30/3)2             3m
                         =   124dBuV/m

                    Test Report No.: RF190103N022

    4.2.3 TEST PROCEDURE

    < Below 30MHz >
      a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at
         a 10 meters Semi-anechoic chamber room. The table was rotated 360 degrees to
         determine the position of the highest radiation.
      b. The EUT was set 3 meters away from the interference-receiving antenna, which
         was mounted on the top of a variable-height antenna tower.
      c. The height of antenna 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.
      d. 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.
      e. The test-receiver system was set to quasi-peak detect function and specified
         bandwidth with maximum hold mode when the test frequency is below 1 GHz.
      f. For below 30MHz, a loop antenna with its vertical plane is place 3m from the EUT
         and rotated about its vertical axis for maximum response at each azimuth about the
         EUT. And the centre of the loop shall be 1m above the ground.
    <30MHz~1GHz >
      a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at
         a 3 meters semi-anechoic chamber. The table was rotated 360 degrees to
         determine the position of the highest radiation.
      b. The EUT was set 3 meters away from the interference-receiving antenna, which
         was mounted on the top of a variable-height antenna tower.
      c. The antenna is a broadband antenna, and its 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.
      d. 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.
      e. The test-receiver system was set to Peak Detect Function and Specified
         Bandwidth with Maximum Hold Mode.

      NOTE:
      1. The resolution bandwidth of test receiver/spectrum analyzer is 120kHz for Quasi-peak detection (QP) at
         frequency below 1GHz.
      2. Emission level(dBuV/m)=Raw Value(dBuV) + Correction Factor(dB/m)
      3. Correction Factor(dB/m) = Antenna Factor (dB/m) + Cable Factor (dB)
      4. Margin value = Emission level – Limit value.

    4.2.4 DEVIATION FROM TEST STANDARD

    No deviation.

                    Test Report No.: RF190103N022


    4.3.3 TEST PROCEDURE
      a. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
          from an external generator.

      b. Turn on the EUT and connect it to measurement instrument. 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.

      c. Measure the frequency difference of two frequencies that were attenuated 20dB from the reference level.
          Record the frequency difference as the emission bandwidth.

      d. Repeat above procedures until all frequencies measured were complete.
