The EUT is placed on a 0.8m high insulating table, which stands on the grounded conducting floor,
and keeps 0.4m away from the grounded conducting wall. The EUT is connected to the power mains
through a LISN which provides 50Ω/50µH of coupling impedance for the measuring instrument. A
Pulse Limiter is used to protect the measuring instrument. The factors of the whole test system are
calibrated to correct the reading.

2.2.2   Radiated Emission

A. Test Setup:

    1) For radiated emissions from 9kHz to 30MHz




    2) For radiated emissions from 30MHz to1GHz




                                                                 Page 8 of 16

    3) For radiated emissions above 1GHz




The test is performed in a 3m Semi-Anechoic Chamber; the antenna factor, cable loss and so on of the
site (factors) is calculated to correct the reading. The EUT is placed on a 0.8m high insulating Turn
Table, and keeps 3m away from the Test Antenna, which is mounted on a variable-height antenna
master tower.

For the test Antenna:

1) In the frequency range of 9KHz to 30MHz, magnetic field is measured with Loop Test Antenna.

    The Test Antenna is positioned with its plane vertical at 1m distance from the EUT. The center of
    the Loop Test Antenna is 1m above the ground. During the measurement the Loop Test Antenna
    rotates about its vertical axis for maximum response at each azimuth about the EUT.

2) In the frequency range above 30MHz, Bi-Log Test Antenna (30MHz to 1GHz) and Horn Test
   Antenna (above 1GHz) are used. Test Antenna is 3m away from the EUT. Test Antenna height is
   varied from 1m to 4m above the ground to determine the maximum value of the field strength.
   The emission levels at both horizontal and vertical polarizations should be tested.

power line on any frequency within the band 150kHz to 30MHz shall not exceed the limits in the
following table, as measured using a 50µH/50Ω line impedance stabilization network (LISN).

3.1.2    Test Description

See section 2.2.1 of this report.

3.1.3    Test Result

The maximum conducted interference is searched using Peak (PK), Quasi-peak (QP) and Average
(AV) detectors; the emission levels more than the AV and QP limits, and that have narrow margins
from the AV and QP limits will be re-measured with AV and QP detectors. Tests for both L phase and
N phase lines of the power mains connected to the EUT are performed. All test modes are considered,
refer to recorded points and plots below.

3.2       Radiated Emission

3.2.1     Requirement

According to FCC section 15.109(a)(e), the field strength of radiated emissions from unintentional
radiators at a distance of 3 meters shall not exceed the following values:

        Frequency          Field Strength        Field Strength Limitation at 3m Measurement Dist
      range (MHz)         µV/m            Dist           (uV/m)                  (dBuV/m)

      1.705 - 30.00         30            30m            100*30                 20log 30 + 40
       30.0 - 88.0         100             3m              100                    20log 100
       88.0 - 216.0        150             3m              150                    20log 150
      216.0 - 960.0        200             3m              200                    20log 200
      Above 960.0          500             3m              500                    20log 500

Note: The limits of frequency below 30MHz is quoted from FCC section 15.209.

As shown in FCC section 15.35(b), for frequencies above 1000MHz, the field strength limits are
based on average detector. When average radiated emission measurements are specified in this part,
including emission measurements below 1000MHz, there also is a limit on the radio frequency
emissions, as measured using instrumentation with a peak detector function, corresponding to 20dB
above the maximum permitted average limit for the frequency being investigated unless a different
peak emission limit is otherwise specified in the rules.

Note:
1) The tighter limit shall apply at the boundary between two frequency range.
2) Limitation expressed in dBuV/m is calculated by 20log Emission Level(uV/m).
3) If measurement is made at 3m distance, then F.S Limitation at 3m distance is adjusted by using
    the formula of Ld1 = Ld2 * (d2/d1)2.
    Example:
    F.S Limit at 30m distance is 30uV/m, then F.S Limitation at 3m distance is adjusted as
    Ld1 = L1 = 30uV/m * (10)2 = 100 * 30uV/m

3.2.2     Test Description

See section 2.2.2 of this report.

3.2.3     Frequency range of measurement

Highest frequency generated or used in the device is the highest speed of the processor, lowest


                                                                                    Page 13 of 16

frequency generated or used in the device is the lowest frequency of the oscillator. According to
15.33(b)(1), the frequency range of radiated measurement for the EUT is listed in the following table:

                                                                                                             Frequency range of radiated

          Highest                                            100MHz                                                    1GHz

3.2.4        Test Result

The maximum radiated emission is searched using PK, QP and AV detectors; the emission levels
more than the limits, and that have narrow margins from the limits will be re-measured with AV and
QP detectors. Both the vertical and the horizontal polarizations of the Test Antenna are considered to
perform the tests. All test modes are considered, refer to recorded points and plots below.

The amplitude of spurious emissions which are attenuated more than 20 dB below the permissible
value need not be reported.

Note: All radiated emission tests were performed in X, Y, Z axis direction, and only the worst axis test
condition was recorded in this test report.

B. Test Plots and Suspicious Points:

    NOTE: The emissions are too small to be measured and are at least 6 dB below the limit, So all
    the data of marked are pass.
