  Test Setup:




  Test Mode:                Charging + Transmitting Mode
                            1. The E.U.T is connected to an adapter through a line
                               impedance stabilization network (L.I.S.N.). This
                               provides a 50ohm/50uH coupling impedance for the
                               measuring equipment.
                            2. The peripheral devices are also connected to the main
                               power through a LISN that provides a 50ohm/50uH
                               coupling impedance with 50ohm termination. (Please

                               photographs).
                            3. Both sides of A.C. line are checked for maximum
                               conducted interference. In order to find the maximum
                               emission, the relative positions of equipment and all of
                               the interface cables must be changed according to

                  Above 1GHz




                  1. For the radiated emission test below 1GHz:
                      The EUT was placed on a turntable with 0.8 meter
                      above ground. The EUT was set 3 meters from the
                      interference receiving antenna, which was mounted
                      on the top of a variable height antenna tower. The
                      EUT was arranged to its worst case and then tune
                      the antenna tower (from 1 m to 4 m) and turntable
                      (from 0 degree to 360 degrees) 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.
                      For the radiated emission test above 1GHz:
                      Place the measurement antenna on a turntable with
Test Procedure:
                      1.5 meter above ground, which is away from each
                      area of the EUT determined to be a source of
                      emissions at the specified measurement distance,
                      while keeping the measurement antenna aimed at
                      the source of emissions at each frequency of
                      significant emissions, with polarization oriented for
                      maximum response. The measurement antenna
                      may have to be higher or lower than the EUT,
                      depending on the radiation pattern of the emission
                      and staying aimed at the emission source for
                      receiving the maximum signal. The final
                      measurement antenna elevation shall be that which


                      Page 15 of 29             Report No.: A1908188-C01-R01


                    maximizes the emissions. The measurement
                    antenna elevation for maximum emissions shall be
                    restricted to a range of heights of from 1 m to 4 m
                    above the ground or reference ground plane.
                2. Corrected Reading: Antenna Factor + Cable Loss +
                    Read Level - Preamp Factor = Level
                3. For measurement below 1GHz, If the emission level
                    of the EUT measured by the peak detector is 3 dB
                    lower than the applicable limit, the peak emission
                    level will be reported. Otherwise, the emission
                    measurement will be repeated using the quasi-peak
                    detector and reported.
                4. Use the following spectrum analyzer settings:
                   (1) Span shall wide enough to fully capture the
                        emission being measured;
                   (2) Set RBW=100 kHz for f < 1 GHz; VBW ≥        RBW;
                        Sweep = auto; Detector function = peak; Trace =
                        max hold;
                   (3) Set RBW = 1 MHz, VBW= 3MHz for f  1 GHz
                        for peak measurement.
                    For average measurement: VBW = 10 Hz, when
                    duty cycle is no less than 98 percent. VBW ≥1/T,
                    when duty cycle is less than 98 percent where T is
                    the minimum transmission duration over which the
                    transmitter is on and is transmitting at its maximum
                    power control level for the tested mode of operation.
Test results:   PASS

4. Antenna Requirements
4.1. Limit
   15.203 requirement:
   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, 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.
4.2. Result
   The antenna is coil antenna which permanently attached. It complies with the standard
   requirement.
