4.7. 26dBc Bandwidth

TEST CONFIGURATION

                                                        SPECTRUM
                    EUT
                                                        ANALYZER


TEST PROCEDURE

According to KDB789033 D02 General UNII Test Procedures New Rules v01 for one of the following
procedures may be used for Emission Bandwidth (EBW) measurement:
a. Set RBW = 300 kHz (approximately 1% of the emission bandwidth).
b. Set the video bandwidth (VBW) = 1000 KHz (VBW > RBW)
c. Detector = Peak.
d. Trace mode = max hold.
e. Sweep = auto couple.
f. Allow the trace to stabilize
g. Measure the maximum width of the emission that is 26 dB down from the maximum of the emission.
    Compare this with the RBW setting of the analyzer. Readjust RBW and repeat measurement as needed
    until the RBW/EBW ratio is approximately 1%.
Note: The automatic bandwidth measurement capability of a spectrum analyzer or EMI receiver may be
employed if it implements the functionality described above.

TEST PROCEDURE

                1. The EUT was placed on a turn table which is 1.5m above 1GHz.
                2. Maximum procedure was performed by raising the receiving antenna from 1m to 4m and
                   rotating the turn table from 0° to 360° to acquire the highest emissions from EUT.
                3. And also, each emission was to be maximized by changing the polarization of receiving
                   antenna both horizontal and vertical.
                4. Repeat above procedures until all frequency measurements have been completed..
                5. The distance between test antenna and EUT as following table states:

                                                           Sweep time=Auto

Field Strength Calculation

      The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the
      Amplifier Gain and Duty Cycle Correction Factor(if any) from the measured reading. The basic equation with a
      sample calculation is as follows:

      FS = RA + AF + CL - AG

      Where FS = Field Strength                                 CL = Cable Attenuation Factor (Cable Loss)
         RA = Reading Amplitude                                 AG = Amplifier Gain
         AF = Antenna Factor

REMARKS:
1. Result Level = Read Level + Antenna Factor + Cable loss - PRM Factor.
2. The other emission levels were very low against the limit.
3. The average measurement was not performed when the peak measured data under the limit of average
detection.
4. Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=10Hz/Sweep time=Auto/Detector=Peak;

For Conducted Band edge Measurement
Note:each antenna port have 3dB margin from the limit,so the MIMO mode below the limit.

4.9. Antenna Requirement

Standard Applicable

For intentional device, according to FCC 47 CFR Section 15.203, 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.

And according to FCC 47 CFR Section 15.407 (a), if transmitting antennas of directional gain greater than
6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna
exceeds 6dBi.

Antenna Information

The antenna is PCB antenna, through the buckle stretched out, The directional gains of antenna used for
transmitting is 2.00dBi.
