          3.2 DESCRIPTION OF TEST MODES
          Pre-Scan has been conducted to determine the worst-case mode from all possible
          combinations between available modulations, data rates, XYZ axis and packet type.
          The worst case was found when the EUT was positioned on Y axis for radiated
          emission. The EUT was tested under the following mode.

          4.1     RADIATED EMISSION MEASUREMENT

          4.1.1 LIMITS OF RADIATED EMISSION MEASUREMENT

             Emissions radiated outside of the specified bands, shall be according to the general
             radiated limits in 15.209 as following:
                      FREQUENCIES                 FIELD STRENGTH                  MEASUREMENT DISTANCE

                          88 ~ 216                          150                                       3
                          216 ~ 960                         200                                       3

             According to §15.249(a), the field strength of emissions from intentional radiators
             operated within these frequency bands shall comply with the following:
                       Fundamental                      Field strength of                      Field strength of

                                                       (milli-volts/meter)                    (micro-volts/meter)
                       902-928 MHz                                50                                       500

             The emission limit in this paragraph is based on measurement instrumentation
             employing an quasi-peak(Below 1GHz)/average(Above 1GHz) detector. The
             provisions in §15.35 for limiting peak emissions apply.
                NOTES:
                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.

                        Test Report No.: RF190711N008


          4.1.3 TEST PROCEDURES
           a. The EUT was placed on the top of a rotating table 1.5 meters (above 1GHz) and 0.8
              meters (below 1GHz) 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.
           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.
           g. If the emission level of the EUT in peak mode was lower than the limit specified,
              then testing could be stopped and the peak values of the EUT would be reported.
              Otherwise the emissions would be re-tested one by one using peak, quasi-peak or
              average method as specified and then reported in a data sheet.

           NOTES:
           1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for
              Quasi-peak detection at frequency below 1GHz.
           2. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video bandwidth is 3MHz
              for Peak detection at frequency above 1GHz.
           3. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video bandwidth is
              10Hz for Average detection (AV) at frequency above 1GHz.
           4. All modes of operation were investigated and the worst-case emissions are reported.
           5. The testing of the EUT was performed on all 3 orthogonal axes; the worst-case test configuration
              was reported on the file test setup photo.

                 3. The emission levels of other frequencies were less than 20dB margin against the limit.

                            The emission is fundamental frequency signal which can be ignored.

                        Test Report No.: RF190711N008


          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.


          4.2.4 DEVIATION FROM TEST STANDARD

           No deviation.
