  Notes

  1.       All the measurements in section 15.247 were done based on conducted measurements except
           Radiated Emissions (Spurious Emissions inclusive Restricted Bands Requirement) and Band Edge
           Compliance (Radiated) test.

  2.       The EUT is a Class B device when in non-transmitting state and meets the 47 CFR FCC Part15B
           Class B requirements.

  3.       The maximum measured RF power of the Equipment Under Test is 16.25dBm.

  4.       The Equipment Under Test (EUT) is a DC operated device and contains no provision for public utility
           connections.

  5.       The EUT was operated in continuous transmission, ie 100% duty cycle.

  6.       The EUT was tested using fully charged batteries with DC voltage of 12.0V.

  7.       The RF module of the Equipment Under Test (EUT) is a FCC & IC certified module (FCC ID: N6C-
           SDMAC, IC: 4908A-SDMAC). PCI Limited declares that the module was integrated into the main
           board without modifications in hardware nor firmware and the RF module used was tested and
           reported in UL Japan, Inc. issued test reports, 11182691H-A-R1 and 11182691H-C-R1 dated 7th
           Nov 2016.

  2.1.2     Test Setup
  2.1.2.1   The EUT and supporting equipment were set up in accordance with the requirements of the
            standard as shown in the setup photos.
  2.1.2.2   The filtered power supply for the EUT and supporting equipment were tapped from the appropriate
            power sockets located on the turntable.

  2.1.2.3   The relevant broadband antenna was set at the required test distance away from the EUT and
            supporting equipment boundary.



  2.1.3     Test Method
  2.1.3.1   The EUT was switched on and allowed to warm up to its normal operating condition.
  2.1.3.2   A prescan was carried out to pick the worst emission frequencies from the EUT. For EUT which is a
            portable device, the prescan was carried out by rotating the EUT through three orthogonal axes to
            determine which altitude and equipment arrangement produces such emissions.
  2.1.3.3   The test was carried out at the selected frequency points obtained from the pre-scan. Maximization
            of the emissions, was carried out by rotating the EUT, changing the antenna polarization, and
            adjusting the antenna height in the following manner:
            a.     Vertical or horizontal polarisation (whichever gave the higher emission level over a full rotation
                   of the EUT) was chosen.
            b.     The EUT was then rotated to the direction that gave the maximum emission.
            c.     Finally, the antenna height was adjusted to the height that gave the maximum emission

  2.1.3.4   A Quasi-peak measurement was made for that frequency point if it was less than or equal to
            1GHz.For frequency point in range of 9kHz – 90kHz, 110kHz – 49k0kHz and above 1GHz, both Peak
            and Average measurements were carried out.
  2.1.3.5   The measurements were repeated for the next frequency point, until all selected frequency points
            were measured.

  2.1.3.6   The frequency range covered was from the lowest radio frequency signal generated from the EUT,
            without going below 9kHz to 10th harmonics of the EUT fundamental frequency, using the loop
            antenna for frequency below 30MHz, Bi-log antenna for frequencies from 30MHz up to 1GHz, and
            the Horn antenna above 1GHz.



  Sample Calculation Example

   At 300 MHz                                                           Q-P limit = 46.0 dB V/m

   Log-periodic antenna factor & cable loss at 300 MHz = 18.5 dB
   Q-P reading obtained directly from EMI Receiver = 40.0 dB V/m
   (Calibrated level including antenna factors & cable losses)

   Therefore, Q-P margin = 46.0 - 40.0 = 6.0                          i.e. 6.0 dB below Q-P limit

  Notes

   1.        All possible modes of operation were investigated. Only the worst case emissions measured, using
             the correct CISPR detectors, are reported. All other emissions were relatively insignificant.
   2.        “--” indicates no emissions were found and shows compliance to the limits
   3.        The measurement was done at 10m. The measured results were extrapolated to the specified test
             limits as specified in § 15.209 (a) based on 40dB/decade.
   4.        Quasi-peak measurement was used for frequency measurement up to 1GHz. Average and peak
             measurements were used for emissions above 1GHz. The average measurement was done by
             averaging over a complete cycle of the pulse train, including the blanking interval as the pulse train
             duration does not exceed 0.1 second.
   5.        A "positive" margin indicates a PASS as it refers to the margin present below the limit line at the
             particular frequency. Conversely, a “negative” margin indicates a FAIL.
   6.        EMI receiver Resolution Bandwidth (RBW) and Video Bandwidth (VBW) settings:
             30MHz - 1GHz
             RBW: 120kHz           VBW: 1MHz
             >1GHz
             RBW: 1MHz             VBW: 3MHz
   7.        The upper frequency of radiated emission investigations was according to requirements stated in
             Section 15.33 (a) for intentional radiators & Section 15.33 (b) for unintentional radiators.
   8.        The channel in the table refers to the transmit channel of the EUT.

  2.2       Maximum Peak Power

  2.2.1     Test Limits

  The EUT shows compliance to the requirements of this section, which states the maximum peak power of the
  EUT employing digital modulation shall not exceed 1W (30dBm).



  2.2.2     Test Setup

  2.2.2.1   The EUT and supporting equipment were set up as shown in the setup photo.

  2.2.2.2   The power supply for the EUT was connected to a filtered mains.

  2.2.2.3   The RF antenna connector was connected to a power meter.

  2.2.2.4   All other supporting equipment were powered separately from another filtered mains.



  2.2.3     Test Method

  2.2.3.1   The EUT was switched on and allowed to warm up to its normal operating condition. The EUT was
            then configured to operate in the test mode at lower channel.

  2.2.3.2   The maximum peak power of the transmitting frequency was detected and recorded.

  2.2.3.3   The measurements were repeated if the EUT supports more than one modulation and data rate.

  2.2.3.4   The measurement was repeated with the transmitting frequency was set to middle channel and
            upper channel respectively.

  The EUT shows compliance to the requirements of this section, which states in any 100kHz bandwidth outside
  the frequency band in which the spread spectrum intentional radiator (EUT) is operating, the radio frequency
  power that is produced by the EUT shall be at least 20dB below that in the 100kHz bandwidth within the band
  that contains the highest level of the desired power. In addition, radiated emissions which fall in the restricted
  bands shall comply to the radiated emission limits specified in 15.209.


  2.3.2     Test Setup

  2.3.2.1   The EUT and supporting equipment were set up as shown in the setup photo.

  2.3.2.2   The power supply for the EUT was connected to a filtered mains.

  2.3.2.3   The resolution bandwidth (RBW) and the video bandwidth (VBW) of the spectrum analyser were
            respectively set to 100kHz and 300kHz to show compliance of spurious at band edges are at least
            20dB below the carriers. For restricted band spurious at band edges, peak and average
            measurement plots were taken using the following setting:
            a.    Peak Plot:
                  RBW = 1MHz, VBW = 3RBW
            b.    Average Plot
                  RBW = 1MHz, VBW = 10Hz

  2.3.2.4   All other supporting equipment were powered separately from another filtered mains.


  2.3.3     Test Method

  2.3.3.1   The EUT was switched on and allowed to warm up to its normal operating condition. The EUT was
            then configured to operate in the test mode.

  2.3.3.2   The frequency span of the spectrum analyser was set to wide enough to capture the lower band edge
            of the transmission band, 2.400GHz and any spurious emissions at the band edge.

  2.3.3.3   The spectrum analyser was set to max hold to capture any spurious emissions within the span. The
            signal capturing was continuous until no further spurious emissions were detected.

  2.3.3.4   The measurements were repeated if the EUT supports more than one modulation and data rate.

  2.3.3.5   The measurements were repeated with the frequency span of the spectrum analyser was set to wide
            enough to capture the upper band edge frequency of the transmission band, 2.4835GHz and the any
            spurious emissions at the band-edge.
