          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                             2.66dB
                                                           9KHz ~ 30MHz                            2.74dB
                                                           30MHz ~ 1GHz                            3.55dB
                     Radiated emissions
                                                           1GHz ~ 18GHz                            4.84dB
                                                          18GHz ~ 40GHz                            4.84dB

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

                     Test Report No.:RF150513N020


          4.1.3 TEST PROCEDURES

          The basic test procedure was in accordance with ANSI C63.4 (section 12).

           a. The EUT was placed on the top of a rotating table 1.5 meters above the
              ground at a 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. During the test, each emission was maximized by: having the EUT
              continuously working, investigated all operating modes, rotated about all 3 axis
              (X, Y & Z) and considered typical configuration to obtain worst position,
              manipulating interconnecting cables, For battery operated equipment, the
              equipment tests shall be perform using new battery. The turntable was rotated
              to maximize the emission level.
           g. 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.
           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.
            5. Fundamental AV value =PK Emission +duty cycle.

          NOTE:
             1. The test was performed in RF Oven room.
             2. The calibration interval of the above test instruments is 12 months and the calibrations are
                traceable to CEPREI/CHINA, GRGT/CHINA and NIM/CHINA.


          4.2.3 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.
