1.       General Information

        This report is prepared as a means of presenting test data to be used by a Telecom
Certification Body in determination of whether this product is permitted for unlicensed
dissemination to the general public according to the Innovation, Science, and Economic
Development Canada and FCC Rules and Regulations for RF Devices Intentional
Radiators.

1.1      Product Description

        The Equipment under Test (EUT) is the Radio Systems Corporation Free Spirit
Trainer, Model FS-TRN. The system consists of a receiver collar and a low powered
handheld transmitter. The receiver collar is not evaluated in this test report. The EUT
communicates with the receiver. The EUT is a 433 MHz wireless dog trainer. A transmitter
is paired with a receiver which uses a proprietary RF protocol to wirelessly send tones,
vibrations or static correction command signals

2.     Tests and Measurements

2.1    Configuration of Tested System

       The Test sample was tested per ANSI C63.4, Methods of Measurement from Low-
Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (2014).
Radiated emissions data were taken according to paragraph 8.0 with the test receiver or
spectrum analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz, respectively. All
measurements are peak unless stated otherwise. The video filter associated with the
spectrum analyzer was off throughout the evaluation process. There were no interconnect-
ing cables to manipulate in an attempt to maximize emissions; however, the physical
position of the EUT was varied through the three mutually exclusive orthogonal planes in
an attempt to maximize the emissions. The worse case position is the position used for
final measurements and is gathered in this test report. A block diagram of the tested
system is shown in Figure 1.

2.2    Test Facility

        Testing was performed at US Tech's measurement facility at 3505 Francis Circle,
Alpharetta, GA. This site has been fully described and registered with the FCC, under site
registration number 186022. Additionally this site has also been fully described and
submitted to Industry Canada (IC), and has been approved under file number 9900A-1 and
is also a NVLAP accredited test lab; lab code 200162-0.

2.5      Modifications to Equipment

       No modifications were needed to bring the EUT into compliance with the FCC Part
or IC RSS requirements.

2.6      Test Procedure

       The EUT was configured as shown in the following block diagram(s) and
photograph(s). The sample was tested per ANSI C63.4, Methods of Measurement for Low-
Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (2014)
following US Tech’s procedures paragraph 7 for conducted and paragraph 8 for radiated.
Conducted and radiated emissions data were taken with the test receiver or spectrum
analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz, respectively. All
measurements are peak unless stated otherwise. The video filter on the spectrum
analyzer was OFF throughout the evaluation process. Interconnecting cables were
manipulated as necessary to maximize emissions. The EUT was rotated 360 degrees with
the turntable to maximize emissions. The physical position of the EUT was varied through
the three mutually exclusive orthogonal planes in an attempt to maximize the emissions.
The final setup description is found in the test section of this report.

2.7 Pulse Averaging/Duty Cycle (47 CFR 15.35 (c))

      The duty cycle de-rating factor used in the calculation of average radiated limits (per
CFR 15.209 and 15.35(c)) is described below. This factor was calculated by first
determining the worst case scenario for system operation. With the worst case operating
scenario the transmission duty cycle is calculated as:

                        Total Time On from Figure 3. = 3.05 mS

   (3.05 mS Total Time On)/(100mS FCC Standard) = 0.0305 Numeric Duty Cycle
                     Duty Cycle = 20 Log (0.0305) = -30.31 dB

2.8   Compliance to CFR 15.231(e)

     According to CFR 15.231(e), transmitters which are not able to meet the requirements
for CFR 15.231(a) can evoke the requirements laid out in CFR 15.231(e). In this case the
EUT is not able to meet all the requirements of CFR 15.231(a) therefore CFR 15.231(e)
was applied.

2.8.1 Field Strength of Fundamental (47 CFR 15.231(b), 15.231(e))

       The results of the measurements for peak fundamental emissions are given in Table
4. The EUT emissions measurement was started by setting up the Antenna in the vertical
orientation at a distance of 3 meters from the EUT and at a height of 1.0 meters above the
ground. The EUT’s major axis was set normal to the direction of the measuring antenna.

      The Spectrum Analyzer (SA) displays were set to: Channel A free-running, Channel
B to Max-Hold. Choose a frequency or frequency range and scan it at a coupled rate.
When a signal is detected, raise and lower the antenna to maximize the signal.

       When the signal has been maximized, the antenna height is fixed the turn-table is
rotated through 360 degrees to further maximize the signal.

       When all signals have been maximized for antenna height and direction, the EUT
case is carefully maneuvered in each of the three mutually exclusive orthogonal planes
while observing the same Max-hold/free-running SA display indication. When the EUT
position is found that further maximizes the signal, record the antenna height, rotation
orientation, EUT orthogonal position and signal strength on the data sheet for that
particular frequency.

       Next, the measurement antenna is re-oriented to a Horizontal polarization at 1 meter
height and the process described above is repeated. All signals within 6 dB of the limit are
recorded.

       Finally, the collected data is input into the calculation spread sheet. The spread
sheet is designed to calculate for the true value that is collected. The spread sheet takes
into account the SA reading, the antenna correction factor, cable losses and duty cycle
factors. See the data tables herein.

for limiting peak emissions were applied. All other spurious emissions meets the limits of
15.209.

2.8.3 Bandwidth of Fundamental (CFR15.231(c))

       The bandwidth of the emission shall be no wider than 0.25% of the center frequency
for devices operating above 70 MHz and below 900 MHz. Bandwidth is determined by
those frequencies that are at least 20 dB down on either side of the center frequency of the
pulse.
                         0.0025 x 433,920,000.00 = 1.0848 MHz

   The measured bandwidth is 55.500 kHz, which is well within the limit. See the figure
below.

   When applicable, the EUT is placed in a state representative of how the device will
function under normal operation. The radiated spurious emissions were measured over
                                                                      th
the frequency range of 150 kHz to 30 MHz and 30 MHz to the 5 harmonic of the
fundamental frequency of the intentional transmitter. The test results are shown below.

    The EUT is battery operated and does not connect to the AC mains; therefore testing
for compliance with 15.207 was not applicable.

2.10   Measurement Uncertainty

2.10.1 Conducted Emissions Measurement Uncertainty

       Measurement uncertainty (within a 95% confidence level) for this test is ± 2.85 dB.

       Not applicable. The EUT is battery powered.

2.10.2 Radiated Emissions Measurement Uncertainty

       For a measurement distance of 3 m the measurement uncertainty (with a 95%
confidence level) for this test using a Biconical Antenna (30 MHz to 200 MHz) is ± 5.40 dB.
This value includes all elements of measurement.

The measurement uncertainty (with a 95% confidence level) for this test using a Log
Periodic Antenna (200 MHz to 1000 MHz) is ± 5.19 dB

      The measurement uncertainty (with a 95% confidence level) for this test using a
Horn Antenna is ± 5.08 dB (3 m distance).

      The data listed in this test report does have sufficient margin to negate the effects of
uncertainty. The EUT unconditionally passes this requirement.

3.     Conclusions

        The EUT is deemed to have unconditionally met all the requirements of Title 47
USC Part 2, Subpart J, Equipment Authorization Procedures, Paragraph 2.907,
Certification and Part 15, Subpart C, Intentional Radiators, Paragraph 15.231, Periodic
Operation in the band 40.66 MHz to 40.70 MHz and above 70 MHz and Innovation,
Science, and Economic Development Canada Certification Per RSS-Gen General
Requirements for Radio Apparatus and RSS-210 License-Exempt Radio Apparatus:
Category I Equipment.
