Notes:
 1. All modes of operation and data rates were investigated. The test results shown in the following
    sections represent the worst case emissions.
 2. According to exploratory test no any obvious emission were detected from 9 ㎑ to 30 ㎒.
    Although these tests were performed other than open field site, adequate comparison
    measurements were confirmed against 30 m open field site. Therefore sufficient tests were made
    to demonstrate that the alternative site produces results that correlate with the ones of tests made
    in an open field based on KDB 414788.
 3. The fundamental of the EUT was investigated in three orthogonal orientations X, Y and Z. It was
    determined that X orientation was worst-case orientation. Therefore, all final radiated testing was
    performed with the EUT in X orientation
 4. The test procedure(s) in this report were performed in accordance as following.
      ANSI C63.10-2013
 5. The software and hardware of two earbuds is same. Two earbuds have been tested. However,
    the test result of left earbud is only listed, which is worst-case.

Limit
According to §15.247(b)(3), For systems using digital modulation in the 902-928 ㎒, 2 400-2 483.5
㎒, and 5 725-5 850 ㎒ bands: 1 Watt. As an alternative to a peak power measurement,
compliance with the one Watt limit can be based on a measurement of the maximum conducted
output power. Maximum Conducted Output Power is defined as the total transmit power delivered to
all antennas and antenna elements averaged across all symbols in the signaling alphabet when the
transmitter is operating at its maximum power control level. Power must be summed across all
antennas and antenna elements. The average must not include any time intervals during which
the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are
possible (e.g., alternative modulation methods), the maximum conducted output power is the
highest total transmit power occurring in any mode.

According to §15.247(b)(4) The conducted output power limit specified in paragraph (b) of this
section is based on the use of antennas with directional gains that do not exceed 6 ㏈i. Except as
shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 ㏈i
are used, the conducted output power from the intentional radiator shall be reduced below the
stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in
㏈ that the directional gain of the antenna exceeds 6 ㏈i.

Test settings

General

Section 15.247 permits the maximum conducted (average) output power to be measured as an
alternative to the maximum peak conducted output power for demonstrating compliance to the limit.
When this option is exercised, the measured power is to be referenced to the OBW rather than the
DTS bandwidth (see ANSI C63.10 for measurement guidance).

When using a spectrum analyzer or EMI receiver to perform these measurements, it shall be
capable of utilizing a number of measurement points in each sweep that is greater than or equal to
twice the span/RBW to set a bin-to-bin spacing of ≤ RBW/2 so that narrowband signals are not lost
between frequency bins.

If possible, configure or modify the operation of the EUT so that it transmits continuously at its
maximum power control level. The intent is to test at 100 % duty cycle; however a small reduction in
duty cycle (to no lower than 98 %) is permitted, if required by the EUT for amplitude control
purposes. Manufacturers are expected to provide software to the test lab to permit such continuous
operation.

If continuous transmission (or at least 98 % duty cycle) cannot be achieved due to hardware
limitations (e.g., overheating), the EUT shall be operated at its maximum power control level, with
the transmit duration as long as possible, and the duty cycle as high as possible during which

sweep triggering/signal gating techniques may be used to perform the measurement over the
transmission duration.

Maximum peak conducted output power

One of the following procedures may be used to determine the maximum peak conducted output
power of a DTS EUT.

RBW ≥ DTS bandwidth

The following procedure shall be used when an instrument with a resolution bandwidth that is
greater than the DTS bandwidth is available to perform the measurement:

  a)      Set the RBW ≥ DTS bandwidth.
  b)      Set VBW ≥ [3 × RBW].
  c)      Set span ≥ [3 × RBW].
  d)      Sweep time = auto couple.
  e)      Detector = peak.
  f)      Trace mode = max hold.
  g)      Allow trace to fully stabilize.
  h)      Use peak marker function to determine the peak amplitude level.

Integrated band power method

The following procedure can be used when the maximum available RBW of the instrument is less
than the DTS bandwidth:

  a)      Set the RBW = 1 ㎒.
  b)      Set the VBW ≥ [3 × RBW].
  c)      Set the span ≥ [1.5 × DTS bandwidth].
  d)      Detector = peak.
  e)      Sweep time = auto couple.
  f)      Trace mode = max hold.
  g)      Allow trace to fully stabilize.
  h)      Use the instrument’s band/channel power measurement function with the band limits set
          equal to the DTS bandwidth edges (for some instruments, this may require a manual
          override to select the peak detector). If the instrument does not have a band power function,
          then sum the spectrum levels (in linear power units) at intervals equal to the RBW extending
          across the DTS channel bandwidth.

Test settings

DTS bandwidth

One of the following procedures may be used to determine the modulated DTS bandwidth.

Option 1

1)      Set RBW = 100 ㎑.
2)      Set the video bandwidth (VBW) ≥ 3 x 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 ㏈ relative to the maximum level measured in the fundamental emission.

Option 2

The automatic bandwidth measurement capability of an instrument may be employed using the X dB
bandwidth mode with X set to 6 dB, if the functionality described in 11.8.1 (i.e., RBW = 100 kHz,
VBW ≥ 3 × RBW, and peak detector with maximum hold) is implemented by the instrumentation
function. When using this capability, care shall be taken so that the bandwidth measurement is not
influenced by any intermediate power nulls in the fundamental emission that might be ≥6 dB.

Average field strength measurements

Trace averaging with continuous EUT transmission at full power

If the EUT can be configured or modified to transmit continuously (D ≥ 98%), then the average
emission levels shall be measured using the following method (with EUT transmitting continuously):
  1. RBW = 1 ㎒ (unless otherwise specified).
  2. VBW ≥ (3×RBW).
  3. Detector = RMS (power averaging), if [span / (# of points in sweep)] ≤ (RBW / 2). Satisfying this
     condition may require increasing the number of points in the sweep or reducing the span. If this
     condition cannot be satisfied, then the detector mode shall be set to peak.
  4. Averaging type = power (i.e., rms):
     1) As an alternative, the detector and averaging type may be set for linear voltage averaging.
     2) Some instruments require linear display mode to use linear voltage averaging. Log or ㏈
        averaging shall not be used.
  5. Sweep time = auto.
  6. Perform a trace average of at least 100 traces.

Trace averaging across ON and OFF times of the EUT transmissions followed by duty cycle
correction

If continuous transmission of the EUT (D ≥ 98%) cannot be achieved and the duty cycle is constant
(duty cycle variations are less than ±2%), then the following procedure shall be used:
  1. The EUT shall be configured to operate at the maximum achievable duty cycle.
  2. Measure the duty cycle D of the transmitter output signal as described in 11.6.
  3. RBW = 1 ㎒ (unless otherwise specified).
  4. VBW ≥ [3 × RBW].
  5. Detector = RMS (power averaging), if [span / (# of points in sweep)] ≤ (RBW / 2). Satisfying this
     condition may require increasing the number of points in the sweep or reducing the span. If this
  condition cannot be satisfied, then the detector mode shall be set to peak.

   1) As an alternative, the detector and averaging type may be set for linear voltage averaging.
   2) Some instruments require linear display mode to use linear voltage averaging. Log or ㏈
        averaging shall not be used.
7. Sweep time = auto.
8. Perform a trace average of at least 100 traces.
9. A correction factor shall be added to the measurement results prior to comparing with the emission
   limit to compute the emission level that would have been measured had the test been performed
   at 100% duty cycle. The correction factor is computed as follows:
    1) If power averaging (rms) mode was used in step f), 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 f), 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 (D ≥ 98%) rather than turning ON
        and OFF with with the transmit cycle, then no duty cycle correction is required for that
        emission.
Notes:
 1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 1 ㎒ for
    Peak detection and frequency above 1 ㎓. The resolution bandwidth of test receiver/spectrum
    analyzer is 1 ㎒ and the video bandwidth is 1 ㎑(1/T) for Average detection (AV) at frequency
    above 1 ㎓. (where T = pulse width)
 2. f <30 ㎒, extrapolation factor of 40 ㏈/decade of distance. Fd = 40log(Dm/Ds)
    f ≥30 ㎒, extrapolation factor of 20 ㏈/decade of distance. Fd = 20log(Dm/Ds)
         Where:
                  Fd= Distance factor in ㏈
                  Dm= Measurement distance in meters
                  Ds= Specification distance in meters
 3. Factors(㏈) = Antenna factor(㏈/m) + Cable loss(㏈) + or Amp. gain(㏈) + or Fd(㏈)
 4. The worst-case emissions are reported however emissions whose levels were not within 20 ㏈ of
     respective limits were not reported.
 5. Average test would be performed if the peak result were greater than the average limit.
6. 1) means restricted band.
7. According to part 15.31(f)(2), an extrapolation factor of 40 dB/decade is applied because
    measured distance of radiated emission is 3 m.
