The sample was placed (0.8m below 1GHz, 1.5m above 1GHz) 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. The worst case is X&Z position

3.   CONDUCTED EMISSIONS TEST

 3.1 Conducted Power Line Emission Limit
 For intentional device, according to § 15.207(a) Line Conducted Emission Limits is as following




 * Decreasing linearly with the logarithm of the frequency


 3.2 Test Setup




 3.3 Test Procedure
 1, The equipment was set up as per the test configuration to simulate typical actual usage per the
    user’s manual. The EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is
    placed on the ground plane as per ANSI C63.10.

 2, Support equipment, if needed, was placed as per ANSI C63.10.

 3, All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10.

 4,If a EUT received DC power from the USB Port of Notebook PC, the PC’s adapter received
    AC120V/60Hzpower through a Line Impedance Stabilization Network (LISN) which supplied power
    source and was grounded to the ground plane.

 5, All support equipments received AC power from a second LISN, if any.

 6, The EUT test program was started. Emissions were measured on each current carrying line of the
    EUT using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has
    two monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line
    1connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line
    1connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver.

 7, Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.

4 RADIATED EMISSION TEST

 4.1 Radiation Limit
  For intentional device, according to § 15.209(a), the field strength of radiated emissions from unintentional
  radiators at a distance of 3 meters shall not exceed the following values:




  §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
       frequency                 fundamental              harmonics
                                 (millivolts/meter)       (microvolts/meter)
       2400-2483.5 MHz           50                       500

  §15.249(e) – As shown in §15.35(b), for frequencies above 1000 MHz, the field strength limits in paragraphs
  (a) and (b) of this section are based on average limits. However, the peak field strength of any emission
  shall not exceed the maximum permitted average limits specified above by more than 20 dB under any
  condition of modulation.

  (3)Radiated Emission Test-Up Frequency Above 1GHz




4.3 Test Procedure
 1. Below 1GHz measurement the EUT is placed on turntable which is 0.8m above ground plane.
    And above 1GHz measurement EUT was placed on low permittivity and low tangent turn table
    which is 1.5m above ground plane.
 2. The turntable shall be rotated for 360 degrees to determine the position of maximum emission level..
 3. EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m to find out the
    highest emissions.
 4. Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
 5. And also, each emission was to be maximized by changing the polarization of receiving antenna
    both horizontal and vertical.
 6. Repeat above procedures until the measurements for all frequencies are complete.
 7. The test frequency range from 9KHz to25GHz per FCC PART 15.33(a).

 Note:
 For battery operated equipment, the equipment tests shall be performed using a new battery.

(2) “F” denotes fundamental frequency; “H” denotes spurious frequency. “E” denotes band edge frequency.
(3) * denotes emission frequency which appearing within the Restricted Bands specified in provision of
15.205, then the general radiated emission limits in 15.209 apply.
(4) Data of measurement within this frequency range shown “--- ” in the table above means the reading of
emissions are attenuated more than 20dB below the permissible limits or the field strength is too small to be
measured.
(5) The IF bandwidth of EMI Test Receiver between 30MHz to 1GHz was 120KHz, 1 MHz for measuring
above 1 GHz, below 30MHz was 9KHz.The resolution bandwidth of test receiver/spectrum analyzer is
1MHzand video bandwidth is 3MHz for peak measurement with peak detectorat frequency above 1GHz.The
resolution bandwidth of test receiver/spectrum analyzer is 1MHzand video bandwidth is 10Hz for Average
measurement with peak detection at frequency above 1GHz.
(6) When the test results of Peak Detected below the limits of Average Detected, the Average Detected is
not need completed. For example: Top Channel at Fundamental 73.16dBuV/m(PK Value) <93.98(AV Limit),
at harmonic 53.20 dBuV/m(PK Value) <54 dBuV/m(AV Limit), the Average Detected not need to completed.
(7)All modes of operation were investigated and the worst-case(GFSK Low Channel) emissions is
reported. .

  5 out of Band Emissions

    5.1 Limits
    FCC PART 15.249(d) Emissions radiated outside of the specified frequency bands, except for
    harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general
    radiated emission limits in §15.209, whichever is the lesser attenuation.


    5.2 Test Procedure

    The out of band emission should be measured by following guidance in ANSI C63.10:2013 with respect to
    maximizing the emission by rotating the EUT, measuring the emission while the EUT is situated in three
    orthogonal planes (if appropriate), adjusting the measurement antenna height and polarization ect.

    1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for
    Quasi-peak detection (QP) at frequency below 1GHz.

    2. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is 3 MHz
    for Peak detection (PK) at frequency above 1GHz.

    3. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is 3 MHz
    for Average detection (AV) at frequency above 1GHz.

    5.3 Test Result

              PASS
      All the test modes completed for test. The worst case of Band Edge is GFSK mode;
