1.0   General Description

1.1   Product Description

      The Equipment Under Test (EUT) is a Bluetooth version 4.0 for a Car
      operating from 2402-2480MHz with 2MHz channel spacing. The EUT is
      powered by 4X1.5VDC AA batteries. After switch on the EUT and paired with
      smart device, the EUT can be controlled to move forward, backward, turn
      left/right.

      The Model: 0444 and 0449 are the same as the Model: 0442 in hardware
      aspect. The models are different in model number only.

      Antenna Type: Internal, Integral

      For electronic filing, the brief circuit description is saved with filename: descri.pdf.


1.2   Related Submittal(s) Grants

      This is a single application for certification of a transceiver.


1.3   Test Methodology

      Radiated emission measurements was 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 facility 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.

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 new 4X1.5VDC 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.


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.

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

8.0   Miscellaneous Information

      The miscellaneous information includes details of the test procedure and
      measured bandwidth / calculation of factor such as pulse desensitization and
      averaging factor (calculation and timing diagram).


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).

     Peak Measurement (Bluetooth 4.0 BLE)

     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

     = 90.2 dBµV/m - 39.4 dB
     = 50.8 dBµV/m

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

     = 51.8 dBµV/m - 39.4 dB
     = 12.4 dBµV/m

     Upper bandedge

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

     = 88.4 dBµV/m - 45.3 dB
     = 43.1 dBµV/m

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

     = 50.0 dBµV/m - 45.3 dB
     = 4.7 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).

8.2   Discussion of Pulse Desensitization

      Pulse desensitivity is not applicable for this device. The effective period (Teff)
      is approximately 0.4 ms for a digital “1” bit which illustrated on technical
      specification, with a resolution bandwidth (3dB) of 1MHz, so the pulse
      desensitivity factor is 0dB.


8.3   Calculation of Average Factor

      (Bluetooth 4.0 BLE)
      The duty cycle is simply the on-time divided by the period:

      The duration of one cycle = 100ms

      Effective period of the cycle = 0.4*3 = 1.2ms

      DC = 1.2/100 = 0.012

      Therefore, the averaging factor is found by 20log 0.012 = -38.4dB.

8.4   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.

8.4   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.
