2.2 DESCRIPTION OF TEST MODES
To investigate the maximum EMI emission characteristics generates from EUT, the test system
was pre-scanning tested base on the consideration of following EUT operation mode or test
configuration mode which possible have effect on EMI emission level. Each of these EUT
operation mode(s) or test configuration mode(s) mentioned above was evaluated respectively.

3.2 TEST PROCEDURE
a.The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected to
   the power mains through a line impedance stabilization network (LISN). All other support
   equipments powered from additional LISN(s). The LISN provide 50 Ohm/ 50uH of coupling
   impedance for the measuring instrument.
b.Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back
   and forth in the center forming a bundle 30 to 40 cm long.
c.I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
  cable may be terminated, if required, using the correct terminating impedance. The overall
  length shall not exceed 1 m.
d.LISN at least 80 cm from nearest part of EUT chassis.

e.For the actual test configuration, please refer to the related Item –EUT Test Photos.

         Note: 1.Support units were connected to second LISN.
                 2.Both of LISNs (AMN) are 80 cm from EUT and at least 80

3.4 EUT OPERATING CONDITIONS
The EUT was configured for testing in a typical fashion (as a customer would normally use it). The
EUT has been programmed to continuously transmit during test. This operating condition was
tested and used to collect the included data.

      4. RADIATED EMISSION MEASUREMENT
      4.1 RADIATED EMISSION LIMITS
      (a) The field strength of any emissions within the band 13.553—13.567 MHz shall not exceed
      15,848 microvolts/meter at 30 meters.
      (b) Within the bands 13.410—13.553 MHz and 13.567—13.710 MHz, the field strength of any
      emissions shall not exceed 334 microvolts/meter at 30 meters.
      (c) Within the bands 13.110—13.410 MHz and 13.710—14.010 MHz the field strength of any
      emissions shall not exceed 106 microvolts/meter at 30 meters.
      (d) The field strength of any emissions appearing outside of the 13.110—14.010 MHz band shall not
      exceed the general radiated emission limits in §15.209.

      (Radiated Emission <30MHz (9KHz—30MHz, H—field)
      According to FCC section 15.225, for <30MHz, Radiated emissions were measured according to
      ANSIC63.4. The EUT was set to transmit at the highest output power. The EUT was set 30 meter
      away from the measuring antenna. The loop antenna was positioned 1 meter above the ground
      from the center of the loop. The measuring bandwidth was set to 10KHz. (Note: During testing the
      receive antenna was rotated about its axis to maximize the emission from the EUT)
      There was no detected Restricted bands and Radiated suprious emission below 3OMHz. The 3O0m
      limit was converted to 3m Limit using square factor(x) as it was found by measurements as follows;
      3 m Limit(dBuV/m) = 20log(X)+4010g(30/3)= 20log(15,848)+40l0g(30/3) =124dBuV

      3 m Limit(dBuV/m) = 20log(X)+40l0g(30/3)= 20log(106)+40l0g(30/3) =80.506dBuV

      Except as provided elsewhere in this Subpart, the emissions from an intentional radiator shall not

4.2 TEST PROCEDURE
 a. 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
 b. 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.
 c. In the frequency range above 30MHz, Bi-Log Test Antenna (30MHz to 1GHz) 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.
  f. The initial step in collecting conducted emission data is a spectrum analyzer peak detector
     mode pre-scanning the measurement frequency range. Significant peaks are then marked and
     then Quasi Peak detector mode re-measured.
 g. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the
     EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement
     performed.
 h. For the actual test configuration, please refer to the related Item –EUT Test Photos.

NOTE:
Both horizontal and vertical antenna polarities were tested
and performed pretest to three orthogonal axis. The worst case emissions were reported

4.5 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
For example

Frequency              FS          RA           AF          CL           AG          Factor

6. 20DB BANDWIDTH
6.1 APPLIED PROCEDURES / LIMIT
According to FCC section 15.215(c), the 20dB bandwidth should be contained within the frequency
band designated in the rule section under which the EUT is operated, it was measured with a
spectrum analyzer connected the EUT while the EUT is operating in transmission mode.
6.2 TEST PROCEDURE
Intentional radiators operating under the alternative provisions to the general emission limits, as
contained in §13.553-13.567 MHz and in subpart E of this part, must be designed to ensure that
the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the
specific rule section under which the equipment operates, is contained within the frequency band
designated in the rule section under which the equipment is operated. In the case of intentional
radiators operating under the provisions of subpart E, the emission bandwidth may span across
multiple contiguous frequency bands identified in that subpart. The requirement to contain the
designated bandwidth of the emission within the specified frequency band includes the effects
from frequency sweeping, frequency hopping and other modulation techniques that may be
employed as well as the frequency stability of the transmitter over expected variations in
temperature and supply voltage. If a frequency stability is not specified in the regulations, it is
recommended that the fundamental emission be kept within at least the central 80% of the
permitted band in order to minimize the possibility of out-of-band operation.
1. Set RBW = 1 kHz.
2. Set the video Mobile Phonewidth (VBW) ≥ 3 RBW.
3. Detector = Peak.
4. Trace mode = max hold.
5. Sweep = auto couple.
6. Allow the trace to stabilize.
7.Measure the maximum width of the emission that is constrained by the frequencies associated
with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 d
B relative to the maximum level measured in the fundamental emission.
