1 General Information

1.1   Purpose of this Report

       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 FCC Rules
and Regulations for RF Devices Intentional Radiators.

1.2   Product Description

        The PetSafe Stance Analyzer is used by veterinarians to determine the
lameness of a dog by measuring individual paw weight. It consists of three parts.
One is handheld transmitter, Model 300-2511, which is being presented for
certification in this test report; the second is a base platform; and the third device
is a receiver station. All units are separate units. When operating the Stance
Analyzer, a dog is placed on the base platform with its paws placed on four
separate pressure pads. The operator presses a button on the handheld
transmitter which then sends an RF command to the receiver and the receiver
communicates this information to a PC via hardwire connections.

1.3   Related Submittal(s)/Grant(s)

1.3.1 The EUT is subject to the following FCC authorizations:

       a)      Certification under section 15.249 as a transmitter
       b)      Verification under 15.101 as a digital device
       c)      The receiver has been evaluated under Part 15 as a DoC device

1.3.2 Certification of the Transmitter

      The EUT is a low power device which falls within the requirements of
15.249. The bandwidth limitations have also been met. Please see the data
presented herein.

1.3.3 Verification of the Digital apparatus

       The Verification requirement shares many common report elements with
the Certification report. Therefore, though this report is mostly intended to
provide data for the Certification process, the Verification authorization report
(part 15.107 and 109) for the PetSafe Stance Analyzer is included herewith.

2 Tests and Measurements

2.1   Configuration of Tested System

       The sample was setup and tested per ANSI C63.4, Methods of
Measurement from Low-Voltage Electrical and Electronic Equipment in the
Frequency Range of 9 kHz to 40 GHz (2003). Conducted and radiated
emissions data were taken with the EMC 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. A Block
diagram of the tested system is shown in Figure 1. A listing of the EUT and its
test peripherals is found in Table 1 below. Test configuration photographs for
spurious and fundamental emissions measurements are in the attached
appendices.

2.6   Measurement Standards (CFR 15.31)

       Intentional and unintentional radiators are to use the methods of ANSI
C63.4 – 2003. Measurements were made on an Open Area Test Site (OATS)
wherever possible. For battery powered equipment, new (or fully charged)
batteries are used. Section 15.31(m) indicates that if the EUT System operates
for example at 906 MHz ISM band, measurements must be made near the
bottom of the band (around 902 MHz for example) and near the top of the band
(908 MHz). However this EUT only operates at 2402 MHz therefore only one
channel, 2402 MHz, was evaluated.

2.7   Frequency Range of Radiated Measurements (CFR 15.33)

       The frequency range is detailed below for intentional and unintentional
radiators.

2.7.1 Frequency Range for Intentional Radiators

      The spectrum was investigated from the lowest RF signal generated
without going below 9 kHz to the 10th harmonic of the highest fundamental
transmitter frequency.

2.7.2 Frequency Range for Unintentional Radiators

      The spectrum was investigated from the lowest RF signal generated
without going below the lowest frequency for which an emissions limit is specified
(30 MHz) to the 5th harmonic of the highest fundamental frequency of the digital
device (5 GHz maximum).

2.7.3 Measurement Detector Function and Bandwidth (CFR 15.35)

        On any frequency below 1000 MHz, the limits shown are based upon
measuring equipment employing a CISPR quasi-peak detector function and
related measurement bandwidths. On frequencies above 1000 MHz, the
radiation limits are based upon the use of measuring instrumentation employing
an average detector function.

      When average detector measurements are specified for use, including
emission measurements below 1000 MHz, there is also a corresponding limit for
Peak detector measurements having a limit of 20 dB above the corresponding
average limit unless a different peak emission limit is specified. Measurements
above 1000 MHz utilize a minimum resolution bandwidth of 1 MHz.

       When radiated emissions limits are expressed in terms of the average
value of the emission and pulsed operation is employed, the measurement field
strength is determined by averaging over one complete pulse train (Duty Cycle)
including blanking intervals for pulse trains up to 0.1 second in duration. The
exact method of calculating the average field strength is included in paragraph
2.11 of this report. Refer to Figures 1 for duty cycle measurement data.

                   13.6 mS/100mS = 0.136 = 13.6 percent


                         DC = 20 Log(0.136) = -17.32

2.8    Antenna Requirement (CFR 15.203)

       The intentional radiator is designed to assure that no antenna other than
that furnished by the manufacturer is used with the device. The use of a
permanently attached antenna is considered sufficient to comply with this
requirement. Below is a table of the permanently attached antenna used with this
system and its characteristics. If, in the future, additional antennas are
contemplated for use, they must be formally evaluated and approved for
suitability to these requirements.

2.10 Intentional Radiator, Radiated Emissions (CFR 15.249 (a), (e))

    The EUT frequency hopping was stopped and it was placed into a continuous
transmit mode of operation. A preliminary scan was performed on the EUT to find
signal frequencies that were caused by the transmitter part of the product and to
obtain the worse case result the EUT tested in all X, Y and Z axis. Radiated
measurements below 1 GHz were tested with a RBW = 120 kHz. Radiated
measurements above 1 GHz were measured using a RBW =1 MHz VBW = 3
MHz. Test data is found in Tables 4 and 5.


2.11 Restricted Bands of Operation (CFR 15.205)

    Only radiated harmonics and other spurious signals can be permitted to fall
into the restricted bands of 15.205. All signals found in paragraph 2.7 above shall
be examined for this requirement. Limits are based upon the limits of paragraph
15.209. Above 1 GHz, the limits are for Average value. See Tables 4 and 5
below for peak and Average measurements. According to CFR 15.35, the peak
limits can exceed the average limits by 20 dB.

2.12    20 dB Bandwidth Measurement & Channel Spacing per CFR 15.249,
       99% Occupied Bandwidth (IC RSS 210, A8.1)

2.12.1    20 dB Bandwidth Measurements

   The EUT antenna port was connected to a spectrum analyzer having a 50 Ω
input impedance. Measurements were performed similar to the method of FCC,
KDB Publication No. DA 00-705 for a bandwidth of 20 dB. The RBW was set to
approximately 1/100 of the manufacturers claimed RBW and with the VBW ≥
RBW. The results of this test are given in Table 13 and Figures 23 through 25.

   The above method was not possible. The EUT does not have an antenna
port; the test was preformed using the alternate radiated method per KDB
publication No. DA 00-705.

Bandwidth = 537 KHz

2.13 Band Edge Measurements (CFR15.249(d))

       The EUT has only one fundamental frequency. Therefore the Band Edge
measurements were made at one frequency. A measurement was made of the
fundamental and the emission was measured using a quasi peak setting. A
Resolution Bandwidth of > 1% of the emission bandwidth was used. This
procedure was repeated for the high side. The limits were derived in the
following sections.

2.13.1 High Band Edge

       Above 906 MHz the limit per section 15.249(d) is 50 db below the
fundamental or the value expressed by CFR 15.209 (46 dBuV/m) whichever is
the lesser attenuation.

The channel fundamental recorded in Table 5 is 77.68 dBuV/m:
77.68 dBuV – 32.80dB = 44.88 dBuV/m
Passing Margin= (50) – 44.88= 5.12 dB

2.15 Unintentional Radiator, Radiated Emissions (CFR 15.109)

    Radiated emissions within the band 30 MHz to 12.5 GHz were measured with
a spectrum analyzer via a pre-amplifier by connecting the spectrum analyzer to a
receiving antenna spaced three (3) meters from the EUT. The spectrum analyzer
was set for a 50 Ω input impedance with the VBW set to > the RBW bandwidth.
The antenna was raised and lowered over a span of 4 meters in order to
maximize the signal coming from the EUT. Similarly, the turntable was rotated
through 360 degrees in the same maximizing effort. Also the EUT was scanned
for a maxima when placed in each of the three mutually exclusive orthogonal
planes. The results of the measurements are given in Table 9.

2.16 Measurement Uncertainty

       The measurement uncertainties given were calculated using the method
detailed in CISPR 16-4. A coverage factor of k=2 was used to give a level of
confidence of approximately 95%.


2.16.1 Conducted Emissions Measurement Uncertainty:

      Measurement Uncertainty (within a 95% confidence level) for this test is
±2.8 dB.

       This measurement was not applicable to this EUT.

2.16.2 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 ±5.3 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 ±5.1 dB.

       The measurement uncertainty (with a 95% confidence level) for this test
using a Horn Antenna is ±5.1 dB.

       The data listed in this test report does have sufficient margin to negate the
effects of uncertainty, therefore, this test is unconditionally acceptable.
