3.0   Test Methodology

3.1   Radiated Emission

      The sample was placed 0.8m above the ground plane on a standard emission test
      site *. 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 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.



3.2   Field Strength Calculation

      The field strength at 3 m was established by adding the meter reading of the
      spectrum analyzer to the factors associated with antenna correction factor, cable
      loss, preamplifiers and filter attenuation.

      The equation is expressed as follow:

      FS = R + System Factor
      System Factor = AF + CF + FA – PA

      Where FS = Net Field Strength in dBuV/m at 3 meters.
            R = Reading of Spectrum Analyzer / Test Receiver in dBuV.
            AF = Antenna Factor in dB.
            CF = Cable Attenuation Factor in dB.
            FA = Filter Attenuation Factor in dB.
            PA = Preamplifier Factor in dB.

      FA and PA are only be used for the measuring frequency above 1 GHz.


3.3   Conducted Emissions

      The test was performed in accordance with ANSI C63.4: 2003, with the following:
      initial measurements were performed in peak and average detection modes on the
      live line of personal computer, any emissions recorded within 30dB of the relevant
      limit lines were re-measured using quasi-peak and average detection on the live and
      neutral lines with the worst case recorded in the table of results.

4.2     20dB Bandwidth Measurement

        Test Requirement:                     FCC part 15 section 15.247 (a1)
        Test Date:                            2012-05-31
        Mode of Operation:                    Transmitting mode.
        Detector Function:                     Max Hold



Test Setup:

The bandwidth is measured at an amplitude level reduced from the reference level by a specified ratio. The
reference level is the level of the highest amplitude signal observed from the transmitter at the fundamental
frequency. Once the reference level is established, the equipment is conditioned with typical modulating
signal to produce the worst-case (i.e. the widest) bandwidth.

              Lowest                                  2.402                                0.910

4.3     Hopping Channel Carrier Frequency Separation

        Test Requirement:                    FCC part 15 section 15.247 (a1)
        Test Date:                           2012-05-31
        Mode of Operation:                   Transmitting mode.
        Detector Function:                    Max Hold


Result: PASS

Measured Result :
Refer to the delta marker, the frequency separation between two adjacent channels is 1.005 MHz, therefore,
the requirement of channel separated by a two-third of the 20dB bandwidth of the hopping channel is applied.

According to the test result shown in section 4.2, the maximum 20dB bandwidth is 0.923 MHz, so the hopping
channel separation of this EUT is found to comply with the requirement.

Limits for Hopping Channel Separation [ Section 15.247 (a1) ]:

Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of
25kHz or the 20dB bandwidth of the hopping channel, whichever is greater. Alternatively, frequency hopping
systems operating in the 2400-2483.5MHz band may have hopping channel carrier frequencies that are
separated by 25kHz or two-thirds of the 20dB bandwidth of the hopping channel, whichever is greater.

Result data graph shows the channel separation

Out of Frequency Band Emissions:

For out of band emissions that are close to or exceed 20dB attenuation requirement, and
emission falls into restricted band, radiated emission was performed in order to show
compliance with the general radiated emission requirement.



Result Summary:

Refer to the data graph for the emission data graph, result shows that the significant
emissions detected are with more than 20dB below that in the 100kHz bandwidth within the
band that contains the highest level of the desired power.



Limits for Out of Frequency Band Emission [ Section 15.247 (d) ]:

In any 100kHz bandwidth outside the frequency band in which the spread spectrum or
digitally modulated intentional radiator is operating, the radio frequency power that is
produced by the intentional radiator shall be at least 20 dB below that in the 100kHz
bandwidth within the band that contains the highest level of the desired power. Attenuation
below the general limits specified in Section 15.209(a) is not required.

Radiated emissions, which fall in the restricted bands, as defined in Section 15.205(a), must
also comply with the radiated emission limits specified in Section 15.209.

The emission limits shown in the above table are based on measurement employing a CISPR
quasi-peak detector and above 1000MHz are based on measurements employing an average
detector.

Systems operation under the provision of this section shall be operated in a manner that
ensures the public is not exposed to radio frequency energy levels in excess of the
Commission’s guideline,

Frequency Band:               2.402GHz ~2.480GHz

                                 Portable (< 20cm separation )

                                 Occupational/ Controlled exposure
Exposure Classification:
                                 General Population / Uncontrolled exposure
Max. Output Power             0.0019W
Antenna Gain                  0.5 dBi ( Numeric gain: 1.12 )
                                 MPE Evaluation
Evaluation Applied:

SAR Evaluation :

                   Output Power      60 / f(GHz) mW

For 2.480 GHz device requirement:
               Output Power 24.2mW

Therefore, no SAR evaluation required since the transmitter power is below < 24mW
