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. The
Common Antenna is used for the call between the EUT and the System Simulator (SS). A Pulse
Limiter is used to protect the measuring instrument. The factors of the whole test system are
calibrated to correct the reading.

   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.

3.1      Conducted Emission

3.1.1    Requirement

According to FCC section 15.107, the radio frequency voltage that is conducted back onto the AC
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).

                                                    Conducted Limit (dBµV)
 Frequency range (MHz)
                                       Quasi-peak                              Average
        0.15 - 0.50                     66 to 56                               56 to 46
         0.50 - 5                          56                                     46
          5 - 30                           60                                     50
Note:
a) The limit subjects to the Class B digital device.
b) The lower limit shall apply at the band edges.
c) The limit decreases linearly with the logarithm of the frequency in the range 0.15 - 0.50MHz.

3.1.2    Test Description

See section 2.3.1 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.

Note:
  Devices subject to Part 15 must be tested for all available U.S. voltages and frequencies (such as a
Nominal 120V AC,50/60Hz) for which the device is capable of operation. A device rated for 50/60
Hz operation need not be tested at both frequencies provided the radiated and line conducted
emissions are the same at both frequencies.

      a)     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.

      b)    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.

      c) For below 1G :QP detector RBW 120kHz ,VBW 300kHz.

      d) For Above 1G: PK detector RBW 1MHz,VBW 3MHz for PK value ;AV detector RBW
         1MHz, VBW 10Hz for AV value.

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 2.3.2 of this report.

3.2.3    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.
