  The sample was placed 0.8m above the ground plane of 3m chamber. Measurements
  in both horizontal and vertical polarities were performed. 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, rotating
  the turntable, varying antenna height from 1m to 4m in both horizontal and vertical
  polarizations. The emissions worst-case are shown in Test Results of the following
  pages.


4.2.Description of Support Units
 The EUT has been tested as an independent unit together with other necessary
 accessories or support units. The following support units or accessories were used to

 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.
 15.247(c) (1)(i) requirement:
 (i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed.
 Point-to-point operations may employ transmitting antennas with directional gain
 greater than 6dBi provided the maximum conducted output power of the intentional
 radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna
 exceeds 6dBi.
 E.U.T Antenna:
 The Bluetooth antenna is an internal PCB antenna which permanently attached, and
 the best case gain of the antenna is -2dBi.

                                    power through a line impedance stabilization network
                                    (L.I.S.N.). This provides a 50ohm/50uH coupling
                                    impedance for the measuring equipment.

                                    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.
                                5. The test-receiver system was set to Peak Detect

                                   10dB lower than the limit specified, then testing could
                                   be stopped and the peak values of the EUT would be
                                   reported. Otherwise the emissions that did not have
                                   10dB margin would be re-tested one by one using
                                   peak, quasi-peak or average method as specified and
                                   then reported in a data sheet.

6.4.1. Test Specification

  Test Requirement:                        FCC Part15 C Section 15.215(c)
  Test Method:                             ANSI C63.4: 2009
  Limit:                                   N/A
                                           1. According to the follow Test-setup, keep the relative
                                              position between the artificial antenna and the EUT.
                                           2. Set to the maximum power setting and enable the
                                              EUT transmit continuously.
                                           3. Use the following spectrum analyzer settings for
                                              20dB Bandwidth measurement.
                                              Span = approximately 2 to 3 times the 20 dB
                                              bandwidth,
                                              centered on a hopping channel; RBW≥1% of the 20
                                              dB bandwidth;
                                              VBW≥RBW; Sweep = auto; Detector function =
                                              peak; Trace = max hold.
                                           4. Measure and record the results in the test report.



  Test setup:



  Test Mode:                               Transmitting mode with modulation
  Test results:                            Pass
