  3. TEST METHODOLOGY
  The measurement procedure described in the American National Standard of Procedures for
  Compliance Testing of Unlicensed Wireless Devices (ANSI C63.10-2013) is used in the
  measurement of the test device.


  3.1 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.


  3.2 EUT EXERCISE
  The EUT was operated in the engineering 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 15.225 under the FCC Rules Part 15 Subpart C.


  3.3 GENERAL TEST PROCEDURES
  Conducted Emissions
  The EUT is placed on the turntable, which is 0.8 m above ground plane. According to the
  requirements in Section 6.2 of ANSI C63.10. (Version :2013) Conducted emissions from the EUT
  measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-peak and
  average detector modes.
  Radiated Emissions
  The EUT is placed on a turn table, which is 0.8 m above ground plane. 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 max. emission, the relative positions of this hand-held
  transmitter (EUT) was rotated through three orthogonal axes according to the requirements in
  Section 6.3 of ANSI C63.10. (Version: 2013).


  3.4 DESCRIPTION OF TEST MODES
  The EUT has been tested under operating condition. Test program used to control the EUT for
  staying in continuous transmitting and receiving mode is programmed.

  9.1. RADIATED EMISSION 9 kHz – 30 MHz
  Test Set-up




  Test Procedure
  The EUT was placed on a non-conductive table located on semi-anechoic chamber.
  The loop antenna was placed at a location 3m from the EUT. Radiated emissions were measured with the
  loop antenna both parallel and perpendicular to the plane of the EUT loop antenna and with x, y, z planes in
  EUT.

  The limit is converted from microvolts/meter to decibel microvolts/meter. Sample Calculation:


  Corrected Amplitude = Raw Amplitude(dBµV/m) + ACF(dB) + Cable Loss(dB) – Distance Correction Factor



  The spectrum analyzer is set to:
  Frequency Range = 9 kHz ~ 1 GHz
  RBW = 9 kHz (9 kHz ~ 30 MHz)
       = 120 kHz (30 MHz ~ 1 GHz)

  Trace Mode = max hold
  Detector Mode = peak / Quasi-peak
  Sweep time = auto

       Note : The test results for below 30 MHz is correlated to an open site.
             The result on OATS is about 2 dB higher than semi-anechoic chamber(10 m chamber)

       1. Distance Correction Below 30 MHz = 40log(3 m/30 m) = - 40 dB
           Measurement Distance : 3 m (Below 30 MHz)
       2. Factor = Antenna Factor + Cable Loss
       3. Result Level = Read Level + Factor + Distance Correction
       4. Margin = Limit – Result Level
       5. We have done x, y, z planes in EUT
       6. Antenna rotated about its vertical/horizontal axis for maximum response at each
           azimuth position around the EUT.
       7. Worst case of operating mode is type A, analog mode and 106 kbps.

  11. FREQUENCY TOLERANCE

  Procedure: Part 15.225, ANSI 63.10 (Version : 2013)


  If required, the operating or transmitting frequency of an intentional radiator should be measured in
  accordance with the following procedure to ensure that the device operates outside certain precluded
  frequency bands and within the frequency range. No modulation needs to be supplied to the intentional
  radiator during these tests, unless modulation is required to produce an output, e.g., single-sideband
  suppressed carrier transmitters.


  The frequency stability of the transmitter is measured by:


  a) Temperature: The temperature is varied from -20°C to + 50°C using an environmental chamber.
  b) For battery operated equipment, the equipment tests shall be performed using a new battery.
  c) Test Procedure
    - Turn the EUT OFF and place it inside the environmental temperature chamber. For devices that
     have oscillator heaters, energize only the heater circuit.
    - Set the temperature control on the chamber to the highest specified in the regulatoryrequirements
     for the type of device and allow the oscillator heater and the chamber temperatureto stabilize.
    - While maintaining a constant temperature inside the environmental chamber, turn the EUT ON
     and record the operating frequency at startup, and at 2 minutes, 5 minutes, and 10 minutes after
     the EUT is energized. Four measurements in total are made.
   d) The frequency tolerance of the carrier signal shall be maintained within +/- 0.01% of the operating
      frequency.
     Note : Below the measurement result is worst value of the operating frequency at startup, and
            at 2 minutes, 5 minutes, and 10 minutes after the EUT is energized

  12. POWERLINE CONDUCTE EMISSIONS
  LIMIT
  For an intentional radiator which 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 250 microvolt (The limit
  decreases linearly with the logarithm of the frequency in the range 0.15 MHz to 0.50 MHz). The
  limits at specific frequency range is listed as follows:


                                                                Limits (dBμV)
       Frequency Range (MHz)
                                                  Quasi-peak                        Average

               0.15 to 0.50                         66 to 56                         56 to 46

                0.50 to 5                              56                               46

                 5 to 30                               60                               50


  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.


  Test Configuration
  See test photographs attached in Appendix 1 for the actual connections between EUT and support
  equipment.


  TEST PROCEDURE
  1. The EUT is placed on a wooden table 80 cm above the reference ground plane.
  2. The EUT is connected via LISN to a test power supply.
  3. The measurement results are obtained as described below:
  4. Detectors – Quasi Peak and Average Detector.
  5. The EUT is the device operating below 30 MHz.
    - For unterminated the Antenna, the AC line conducted tests are performed with the antenna
    connected
    - For terminated the Antenna, the AC line conducted tests are performed with a dummy load
    connected to the EUT antenna output terminal.


  Sample Calculation
  Quasi-peak(Final Result) = Reading Value + Correction Factor
