2. Test Methodology
 The measurement procedures described in the ANSI C63.10-2013 and the guidance provided in KDB558074 D01v05r02 were used
 in measurement of the EUT.
 The EUT was tested per the guidance of KDB558074 D01v05r02. And ANSI C63.10-2013 was used to reference appropriate EUT
 setup and maximizing procedures of radiated spurious emission and AC line conducted emission testing.

 2.1 EUT Configuration
 The EUT configuration for testing is installed on RF field strength measurement to meet the Commissions requirement and operating
 in a manner that intends to maximize its emission characteristics in a continuous normal application.

 2.2 EUT Exercise
 The EUT was operated in the test mode to fix the TX frequency that was for the purpose of the measurements. According to its
 specifications, the EUT must comply with the requirements of the Section 15.207, 15.209 and 15.247 under the FCC Rules Part 15
 Subpart C.

 2.3 General Test Procedures
 Conducted Emissions
 The power-line conducted emission test procedure is not described on the KDB558074 D01v05r02.
 So this test was fulfilled with the requirements in Section 6.2 of ANSI C63.10-2013.
 The EUT is placed on the wooden table, which is 0.8 m above ground plane and the conducted emissions from the EUT measured
 in the frequency range between 0.15 MHz and 30 MHz using CISPR Quasi-peak and Average detector.

 Radiated Emissions
 Basically the radiated tests were performed with KDB558074 D01v05r02. But some requirements and procedures like test site
 requirements, EUT setup and maximizing procedure were fulfilled with the requirements in Section 5 and 6 of the ANSI C63.10-2013.
 The EUT is placed on a non-conductive table. For emission measurements at or below 1 GHz, the table height is 80 cm. For
 emission measurements above 1 GHz, the table height is 1.5 m. The turntable shall rotate 360 degrees to determine the position of
 maximum emission level. EUT is set 3 m away from the receiving antenna, which varied from 1 m to 4 m to find out the highest
 emission. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and
 vertical. In order to find out the highest emission, the relative positions of the EUT were rotated through three orthogonal axes.

 2.4 Description of Test Modes
 The EUT has been tested with the operating condition for maximizing the emission characteristics. A test program is used to control
 the EUT for staying in continuous transmitting. The Bluetooth low energy mode with below low, middle and high channels were
 tested and reported.

3.5.1 Test Setup
     Not tested

3.5.2 Test Procedures
 1. The EUT is placed on a non-conductive table.                   For emission measurements at or below 1 GHz, the table height is
     80 cm. For emission measurements above 1 GHz, the table height is 1.5 m.
2. The turntable shall be rotated for 360 degrees to determine the position of maximum emission level.
3. EUT is set 3 m away from the receiving antenna, which is varied from 1 m to 4 m to find out the highest emissions.
4. Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
 5. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal
     and vertical.
6. Repeat above procedures until the measurements for all frequencies are complete.

Note: Measurement Instrument Setting for Radiated Emission Measurements.

    2. Frequency Range > 1 GHz

      Average Measurement> 1GHz
      1. RBW = 1 MHz (unless otherwise specified).
      2. VBW ≥ 3 x RBW.
      3. Detector = RMS (Number of points           ≥ 2 x Span / RBW)
      4. Averaging type = power (i.e., RMS).
      5. Sweep time = auto.
      6. Perform a trace average of at least 100 traces.
       7. A correction factor shall be added to the measurement results prior to comparing to the emission limit in order to compute
        the emission level that would have been measured had the test been performed at 100 percent duty cycle. The correction
        factor is computed as follows:

      1) If power averaging (RMS) mode was used in step 4, then the applicable correction factor is 10 log(1/D), where D is the duty cycle.
      2) If linear voltage averaging mode was used in step 4, then the applicable correction factor is 20 log(1/D), where D is the duty cycle.
      3) If a specific emission is demonstrated to be continuous (≥ 98 percent duty cycle) rather than turning on and off with the transmit cycle, then
         no duty cycle correction is required for that emission.

▪ Note.
 1. The radiated emissions were investigated 9kHz to 25GHz. And no other spurious and harmonic emissions were found above listed frequencies.
 2. Information of Distance Factor
   For finding emissions, the test distance might be reduced from 3 m to 1 m. In this case, the distance factor (-9.54 dB) is applied to the result.
   - Calculation of distance factor = 20 log( applied distance / required distance ) = 20 log( 1 m / 3 m ) = -9.54 dB
   When distance factor is “N/A”, the distance is 3 m and distance factor is not applied.
 3. Sample Calculation.
   Margin = Limit – Result /    Result = Reading + T.F + D.C.F / T.F = AF + CL – AG
   Where, T.F = Total Factor,   AF = Antenna Factor,    CL = Cable Loss, AG = Amplifier Gain,
   DCF = Duty Cycle Correction Factor.

▪ Note.
 1. The radiated emissions were investigated 9kHz to 25GHz. And no other spurious and harmonic emissions were found above listed frequencies.
 2. Information of Distance Factor
   For finding emissions, the test distance might be reduced from 3 m to 1 m. In this case, the distance factor (-9.54 dB) is applied to the result.
   - Calculation of distance factor = 20 log( applied distance / required distance ) = 20 log( 1 m / 3 m ) = -9.54 dB
   When distance factor is “N/A”, the distance is 3 m and distance factor is not applied.
 3. Sample Calculation.
   Margin = Limit – Result /    Result = Reading + T.F + D.C.F / T.F = AF + CL – AG
   Where, T.F = Total Factor,   AF = Antenna Factor,    CL = Cable Loss, AG = Amplifier Gain,
   DCF = Duty Cycle Correction Factor.

3.6 Power line Conducted Emissions
 ▣ Test Requirements and limit, §15.207 & RSS-Gen [8.8]
  For an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency
  voltage that is conducted back onto the AC power line on any frequency or frequencies, within the band 150 kHz to
  30 MHz, shall not exceed the limits in the following table, as measured using a 50 μH/50 ohms line impedance
  stabilization network (LISN).


                                                                        Conducted Limit (dBuV)

   * Decreases with the logarithm of the frequency

  Compliance with this provision shall be based on the measurement of the radio frequency voltage between each
  power line (LINE and NEUTRAL) and ground at the power terminals.

 3.6.1 Test Setup
See test photographs for the actual connections between EUT and support equipment.

 3.6.2 Test Procedures
Conducted emissions from the EUT were measured according to the ANSI C63.10-2013.
1. The test procedure is performed in a 6.5 m × 3.5 m × 3.5 m (L × W × H) shielded room. The EUT along with its
   peripherals were placed on a 1.0 m (W) × 1.5 m (L) and 0.8 m in height wooden table and the EUT was adjusted to
   maintain a 0.4 meter space from a vertical reference plane.
2. The EUT was connected to power mains through a line impedance stabilization network (LISN) which provides 50
   ohm coupling impedance for measuring instrument and the chassis ground was bounded to the horizontal ground
   plane of shielded room.
3. All peripherals were connected to the second LISN and the chassis ground also bounded to the horizontal ground
   plane of shielded room.
4. The excess power cable between the EUT and the LISN was bundled. The power cables of peripherals were
   unbundled. All connecting cables of EUT and peripherals were moved to find the maximum emission.

4. ANTENNA REQUIREMENTS
▣ According to FCC 47 CFR §15.203
“An intentional radiator antenna shall be designed to ensure that no antenna other than that furnished by the responsible
party can 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 antenna is permanently attached on PCB. (Refer to Internal photo file.)
 Therefore this E.U.T Complies with the requirement of §15.203

APPENDIX II
Duty cycle plots
▪ Test Procedure
Duty Cycle was measured using Section 6.0 b) of KDB558074 D01v05r02 :
The zero-span mode on a spectrum analyzer or EMI receiver if the response time and spacing between bins on the
sweep are sufficient to permit accurate measurements of the on and off times of the transmitted signal. Set the center
frequency of the instrument to the center frequency of the transmission. Set RBW ≥ OBW if possible; otherwise, set
RBW to the largest available value. Set VBW ≥ RBW. Set detector = peak or average.
The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T and the number of sweep
points across duration T exceeds 100. (For example, if VBW and/or RBW are limited to 3 MHz, then the zero-span
method of measuring duty cycle shall not be used if T ≤ 16.7 microseconds.)
