1.2   Related Submittal(s) Grants

      This is a single application for certification of a transceiver.


1.3   Test Methodology

      Radiated emission measurements were performed according to the procedures in ANSI C63.10
      (2013). All radiated measurements were performed in an 3m Chamber. Preliminary scans
      were performed in the 3m Chamber only to determine worst case modes. All radiated tests
      were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the
      “Justification Section” of this Application.


1.4   Test Facility

      The 3m Chamber used to collect the radiated data is located at Workshop No. 3, G/F., World‐
      Wide Industrial Centre, 43‐47 Shan Mei Street, Fo Tan, Sha Tin, N.T., Hong Kong. This test facility
      and site measurement data have been placed on file with the FCC.

TEST REPORT
2.0   SYSTEM TEST CONFIGURATION
2.1   Justification

      The system was configured for testing in a typical fashion (as a customer would normally use it),
      and in the confines as outlined in ANSI C63.10 (2013).

      The device was powered by DC 6.4V (1 x 6.4V Rechargeable battery) or 6.0V (4 x 1.5V “AA”
      batteries).

      For maximizing emissions, the EUT was rotated through 360°, the antenna height was varied from
      1 meter to 4 meters above the ground plane, and the antenna polarization was changed. This
      step by step procedure for maximizing emissions led to the data reported in Exhibit 3.0.

      The unit was operated standalone and placed in the center of the turntable.

      The equipment under test (EUT) was configured for testing in a typical fashion (as a customer
      would normally use it). The EUT was mounted to a plastic stand if necessary and placed on the
      wooden turntable, which enabled the engineer to maximize emissions through its placement in
      the three orthogonal axes.

      Both rechargeable battery and Alkaline batteries have been considered and tested respectively,
      the worst case data were presented on report.


2.2   EUT Exercising Software

      There was no special software to exercise the device. Once the unit is powered up, it transmits the
      RF signal continuously.


2.3   Special Accessories

      There are no special accessories necessary for compliance of this product.


2.4   Measurement Uncertainty

      When determining of the test conclusion, the Measurement Uncertainty of test has been
      considered.


2.5   Support Equipment List and Description

TEST REPORT

3.0   EMISSION RESULTS

      Data is included of the worst case configuration (the configuration which resulted in the highest
      emission levels). A sample calculation, configuration photographs and data tables of the
      emissions are included.


3.1   Field Strength Calculation

      The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting
      the Amplifier Gain (if any), Average Factor (optional) from the measured reading. The basic
      equation with a sample calculation is as follows:
      FS = RA + AF + CF ‐ AG ‐ AV
      where FS = Field Strength in dBµV/m
                      RA = Receiver Amplitude (including preamplifier) in dBµV
                      CF = Cable Attenuation Factor in dB
                      AF = Antenna Factor in dB
                      AG = Amplifier Gain in dB
                      AV = Average Factor in dB

      In the following table(s), the reading shown on the data table reflects the preamplifier gain. An
      example for the calculations in the following table is as follows:
      FS = RR + LF
      where          FS = Field Strength in dBµV/m
                     RR = RA ‐ AG ‐ AV in dBµV
                     LF = CF + AF in dB

      Assume a receiver reading of 52.0 dBµV is obtained. The antenna factor of 7.4 dB and cable
      factor of 1.6 dB are added. The amplifier gain of 29 dB and average factor of 5 dB are
      subtracted, giving a field strength of 27 dBµV/m. This value in dBµV/m was converted to its
      corresponding level in µV/m.

      RA = 52.0 dBµV/m
      AF = 7.4 dB                          RR = 18.0 dBµV
      CF = 1.6 dB                          LF = 9.0 dB
      AG = 29.0 dB
      AV = 5.0 dB
      FS = RR + LF
      FS = 18 + 9 = 27 dBµV/m

      Level in µV/m = Common Antilogarithm [(27 dBµV/m)/20] = 22.4 µV/m

TEST REPORT

8.0   MISCELLANEOUS INFORMATION

      The miscellaneous information includes details of the test procedure and measured bandwidth.


8.1   Radiated Emission on the Bandedge

      From the following plots, they show that the fundamental emissions are confined in the specified
      band (2400MHz to 2483.5MHz). In case of the fundamental emissions are within two standard
      bandwidths from the bandedge, the delta measurement technique is used for determining
      bandedge compliance. Standard bandwidth is the bandwidth specified by ANSI C63.10 (2013)
      for frequency being measured.

      Emissions radiated outside of the specified frequency bands, except harmonics, are attenuated by
      50dB below the level of the fundamental or to the general radiated emissions limits in
      Section 15.209 , whichever is the lesser attenuation, which meet the requirement of
      part 15.249(d).

TEST REPORT

     PEAK MEASUREMENT

     Bandedge compliance is determined by applying marker‐delta method, i.e. (Bandedge Plot).

     Lower bandedge

     Peak Resultant field strength = Fundamental emissions (peak value) – delta from the plot

     =100.34 dBµV/m – 36.24 dB
     =64.10 dBµV/m

     Average Resultant field strength = Fundamental emissions (average value) – delta from the plot

     =85.27 dBµV/m – 36.24 dB
     =49.03 dBµV/m

     Upper bandedge

     Peak Resultant field strength = Fundamental emissions (peak value) – delta from the plot

     =97.97 dBµV/m – 41.44 dB
     =56.53 dBµV/m

     Average Resultant field strength = Fundamental emissions (average value) – delta from the plot

     =83.42 dBµV/m – 41.44 dB
     =41.98 dBµV/m

     The resultant field strength meets the general radiated emission limit in Section 15.209, which
     does not exceed 74 dBµV/m (Peak Limit) and 54 dBµV/m (Average Limit).

TEST REPORT
8.2   Emissions Test Procedures

      The following is a description of the test procedure used by Intertek Testing Services Hong Kong
      Ltd. in the measurements of transmitter operating under the Part 15, Subpart C rules.

      The transmitting equipment under test (EUT) is placed on a wooden turntable which is four feet in
      diameter and approximately 0.8m in height above the ground plane for emission measurement at
      or below 1GHz and 1.5m in height above the ground plane for emission measurement above
      1GHz. During the radiated emissions test, the turntable is rotated and any cables leaving the EUT
      are manipulated to find the configuration resulting in maximum emissions. The EUT is adjusted
      through all three orthogonal axis to obtain maximum emission levels. The antenna height and
      polarization are also varied during the testing to search for maximum signal levels. The height of
      the antenna is varied from one to four meters.

      Detector function for radiated emissions is in peak mode. Average readings, when required, are
      taken by measuring the duty cycle of the equipment under test and subtracting the corresponding
      amount in dB from the measured peak readings. A detailed description for the calculation of the
      average factor can be found in Exhibit 8.3.

      The frequency range scanned is from the lowest radio frequency signal generated in the device
      which is greater than 9 kHz to the tenth harmonic of the highest fundamental frequency or 40
      GHz, whichever is lower.

                                                                               Intertek Report No:
                                                                               19050224HKG‐001




TEST REPORT
8.2   Emissions Test Procedures (cont’d)

      The EUT is warmed up for 15 minutes prior to the test.

      AC power to the unit is varied from 85% to 115% nominal and variation in the fundamental
      emission field strength is recorded. If battery powered, a new, fully charged battery is used.

      Conducted measurements were made as described in ANSI C63.10 (2013).

      The IF bandwidth used for measurement of radiated signal strength was 100 kHz or greater when
      frequency is below 1000 MHz. Where pulsed transmissions of short enough pulse duration
      warrant, a greater bandwidth is selected according to the recommendations of Hewlett Packard
      Application Note 150‐2. A discussion of whether pulse desensitivity is applicable to this unit is
      included in this report (See Exhibit 8.1). Above 1000 MHz, a resolution bandwidth of 3 MHz is
      used.

      Transmitter measurements are normally conducted at a measurement distance of three
      meters. However, to assure low enough noise floor in the forbidden bands and above 1 GHz,
      signals are acquired at a distance of one meter or less. All measurements are extrapolated to three
      meters using inverse scaling, unless otherwise reported. Measurements taken at a closer
      distance are so marked.
