4. Technical Characteristic Test
4.1 6dB Bandwidth

  Test Procedures(ANSI C63.10-2013 6.9.2)

  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 dB relative to the maximum level measured in the fundamental emission.

  Test Procedures(ANSI C63.10-2013 6.9.3)

  The occupied bandwidth is the frequency bandwidth such that, below its lower and above its
  upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of
  the given emission.
  Use the 99% power bandwidth function of the instrument and report the measured
  bandwidth.

  Test Settings :
  Center frequency = the highest, middle and the lowest channels
  a) RBW = 100 kHz                                     b) VBW ≥ 3 x RBW
  c) Detector = peak                                   d) Trace mode = Max hold
  e) Sweep = auto couple
  f) Allow trace to fully stabilize
  g) 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 dB relative to the maximum level measured in the fundamental
     emission.

4.4 Band Edge & Conducted Spurious emission

  Test Procedures(ANSI C63.10-2013 11.11.3)

 The Unwanted emission from the EUT were measured according to the dictates PKPSD
 measurement procedure in section 11.11 of ANSI C63.10-2013.

 In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or
 digitally modulated device is operating, the RF power that is produced shall be at least 20 dB
 below that in the 100 kHz bandwidth within the band that contains the highest level of the
 desired power, based on either an RF conducted or a radiated measurement, provided that
 the transmitter demonstrates compliance with the peak conducted power limits. If the
 transmitter complies with the conducted power limits based on the use of root-mean-square
 averaging over a time interval, as permitted under Section 5.4(4), the attenuation required
 shall be 30 dB instead of 20 dB. Attenuation below the general field strength limits specified
 in RSS-Gen is not required.


  Test Settings:
  Center frequency = the highest, middle and the lowest channels
  a) RBW = 100 kHz                                    b) VBW ≥ 3 x RBW
  c) Detector = peak                                  d) Sweep time = auto couple
  e) Trace mode= max hold
  f) Allow trace to fully stabilize
  g) Use the peak marker function to determine the maximum amplitude level.


 Limit :

  Emission level    <   20 dBc


 Test results: Complies
    - All conducted emission in any 100kHz bandwidth outside of the spread spectrum band
     was at least 20dB lower than the highest in-band spectral density. Therefore the applying
     equipment meets the requirement.

4.5 Radiated Emission

  Test Location
       10 m SAC (test distance :     10 m,      3 m)
       3 m SAC (test distance : 3 m)


  Test Procedures

  1)     In the frequency range of 9 kHz to 30 MHz, magnetic field is measured with Loop
         Antenna. 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.
  2)     In the frequency rage above 30 MHz, Bi-Log Test Antenna(30 MHz to 1 GHz) and Horn
         Test Antenna(above 1 GHz) are used. Test Antenna is 3m away from the EUT. Test
         Antenna height is carried from 1m to 4m above the ground to determine the maximum
         value of the field strength. The emissions levels at both horizontal and vertical
         polarizations should be tested.

  Instrument Settings

  Frequency Range = 9 kHz ~ 25 GHz (2.4 GHz 10th harmonic)
  a) RBW = 1 MHz for f ≥ 1 GHz, 100 kHz for f < 1 GHz, 9 kHz for f < 30 MHz
  b) VBW ≥ RBW
  c) Sweep time = auto couple

  A radio apparatus that is designed to be connected to the public utility (AC) power line shall
  ensure that the radio frequency voltage, which is conducted back onto the AC power line on
  any frequency or frequencies within the band 150 kHz-30 MHz, shall not exceed the limits.

  Instrument Settings

  IF Band Width: 9 kHz

  Test Procedures

  The EUT was placed on a non-metallic table 0.8m above the metallic, grounded floor
  and 0.4m from the reference ground plane wall. The distance to other metallic surfaces
  was at least 0.8m.
  Amplitude measurements were performed with a quasi-peak detector and an average
  detector.
