3 Test Procedure
POWER LINE CONDUCTED INTERFERENCE: The test procedure used was ANSI Standard
C63.4-2003 using a 50uH LISN. Both Lines were observed. The bandwidth of the receiver
was 10kHz with an appropriate sweep speed. The ambient temperature of the EUT was 25℃
with a humidity of 58%.

RADIATION INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003
using a ANRITSU spectrum analyzer with a pre-selector. The analyzer was calibrated in dB
above a micro volt at the output of the antenna. The resolution bandwidth was 100kHz and the
video bandwidth was 300 kHz up to 1 GHz and 1 MHz with a video BW of 3MHz above 1 GHz.
The ambient temperature of the EUT was 25℃ with a humidity of 58%.

FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by
adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to
the antenna correction factor supplied by the antenna manufacturer and cable loss. The
antenna correction factors and cable loss are stated in terms of dB. The gain of the
Pre-selector was accounted for in the Spectrum Analyzer Meter Reading.
Example:
Freq (MHz) METER READING + ACF + CABLE = FS
33.20 dBuV + 10.36 dB + 0.9 dB= 44.46 dBuV/m @ 3m
ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The EUT was
placed on a table 80 cm high and with dimensions of 1m by 1.5m. The EUT was placed in the
center of the table (1.5m side). The table used for radiated measurements is capable of
continuous rotation. When an emission was found, the table was rotated to produce the
maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m.
The antenna was placed in both the horizontal and vertical planes. The situation was similar
for the conducted measurement except that the table did not rotate. The EUT was setup as
described in ANSI Standard C63.4-2003 10.1.7 with the EUT 40 cm from the vertical ground
wall.

      connected to the power mains through a line impedance stabilization network (L.I.S.N.).
      This provides a 50ohm coupling impedance for the EUT system. Please refer the block
      diagram of the test setup and photographs. Both sides of AC lines are checked to find
      out the maximum conducted emission. In order to find the maximum emission levels,
      the relative positions of equipment and all of the interface cables shall be changed
      according to ANSI C63.4-2003 on Conducted Emission Measurement.
      The bandwidth of test receiver (R & S ESCS30) is set at 9 kHz.

     a) The tighter limit applies at the band edges.
     b) Emission Level(dB uV/m)=20log Emission Level(uV/m)
     c) XX means the limit is unsure

6.3   Test Procedure
      a)    The measuring distance of 3m shall be used for measurements at frequency up to
            1GHZ and above 1 GHZ, The EUT was placed on a rotating 0.8 m high above
             ground. The table was rotated 360 degrees to determine the position of the
             highest radiation

      b)        The Test antenna shall vary between 1m and 4m. Both Horizontal and Vertical
                antenna are set to make measurement.


      c)        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 Qusia Peak Detector mode premeasured

      d)    If Peak value comply with QP limit Below 1GHZ.The EUT deemed to comply with
            QP limit. But the Peak value and average value both need to comply with
            applicable limit above 1GHZ.

      e) Repeated step a and d test with EUT in X, Y,Z position, and the maximum
         emissions data were recorded when EUT in X position as the test photo indicated.




           f)    For the actual test configuration, please see the test setup photo.

         g) Test Equipment Setting For emission test:

          30MHZ~1GHZ:
           RBW 120KHZ VBW 300KHZ

          Above 1GHZ :
           RBW 1MHZ VBW 3MHZ for Peak value
           RBW 1MHZ VBW 10HZ for Average Value

6.4   Test Condition
  A continuously playing MP3 audio source (Ipod, Brand: Apple, Model: A1238,
  S/N: 2Z8181UQYMV) was connected during the test. The volume of the audio
  source was set to maximum to represent the worst case. The transmitter was
  transmitting continuously.
  We have scanned up the 10th harmonics about the EUT.

7 Bandwidth Test

7.1    Limit for Bandwidth

        The occupied bandwidth shall not exceed 200 KHZ


7.2    Method of measurement

      a) The bandwidth is measured at an amplitude level reduced 20dB from the reference
        level. 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.

      b) The test receiver RBW set 10KHZ,VBW set 30KHZ

7.3    Test Setup
       same as section 6.2

8 Band Edge Test

8.1    Test Limit
         Please see the part 15.239a
8.2    Test Procedure

a) Put the EUT on a 0.8m high table,power on the EUT. Emissions were scanned and
  measured rotating the EUT to 360 degrees,Find the maximum Emission

b) Turning to Low and High frequency,then reduced 20dB from the reference level. The
    reference level is the level of the highest amplitude signal observed from the transmitter
    at the fundamental frequency.

c) Check the spurious emissions out of band.

d) RBW,VBW Setting, please see the following test plot.

8.3    Test Results

        Pass

9 Antenna Requirement

9.1   Standard requirement
      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. The use of a
      permanently attached antenna or of an antenna that uses a unique coupling to the
      intentional radiator shall be considered sufficient to comply with the provisions of this
      Section. The manufacturer may design the unit so that a broken antenna can be
      replaced by the user, but the use of a standard antenna jack or electrical connector is
      prohibited.

9.2   Result
       The device is integral antenna, it comply with the standard requirement.
