2.1.1    EUT Configuration
The EUT is configured for testing as depicted in Figure 2.

2.1.2    Modes of Operation
This device is capable of three key modes of operation. Upon manually activated LF interrogation (through the
use of special LF tool at a vehicle dealership), the EUT responds with a single transmission containing a number
of frames used to configure the device with the vehicle. When the EUT is placed in the vehicle tire and the vehicle
drives, it can, in the worst case, periodically transmit where the duration of each transmission is always less than 1
second and the silent period between transmissions is at least 30 times the duration of the transmission, and never
less than 10 seconds. In the case of an emergency condition, the EUT will transmit tire pressure and temperature
information throughout the duration of the condition.

Six samples in total were provided. One sample programmed for periodic transmission, one normal operating sample
capable of LEARN mode transmissions via LF interrogation, two test samples capable of CW transmission (one for
each chassis variant), and two normal samples open for testing and photographs.

2.1.5   Functional Exerciser
Normal operating EUT functionality was verified by observation of transmitted signal.

2.1.6   Modifications Made
There were no modifications made to the EUT by this laboratory.

2.1.7   Production Intent
The EUT appears to be a production ready sample.

2.1.8   Declared Exemptions and Additional Product Notes
The EUT is permanently installed in a transportation vehicle. As such, digital emissions are exempt from US and
Canadian digital emissions regulations (per FCC 15.103(a) and IC correspondence on ICES-003).
   The EUT also employs some modes of operation that alert the vehicle user of sudden changes in tire pressure.
Such alert modes fall under FCC 15.231(a)(4), and may operate during the pendency of the alarm condition. A
detailed list of all operating modes is included in the Description of Operation exhibit included in this application.

3     Emissions
3.1     General Test Procedures
3.1.1    Radiated Test Setup and Procedures
Radiated electromagnetic emissions from the EUT are first evaluated in our shielded fully anechoic chamber. Spec-
trum and modulation characteristics of all emissions are recorded, and emissions above 1 GHz are fully characterized.
The anechoic chamber contains a set-up similar to that of our outdoor 3-meter site, with a turntable and antenna
mast. Instrumentation, including spectrum analyzers and other test equipment as detailed in Section 1.2 are em-
ployed. After indoor pre-scans, emission measurements are made on our outdoor 3-meter Open Area Test Site
(OATS). If the EUT connects to auxiliary equipment and is table or floor standing, the configurations prescribed in
ANSI C63.4 / CISPR-22 are followed. Alternatively, a layout closest to normal use (as declared by the provider)
is employed if the resulting emissions appear to be worst-case in such a configuration. See Figure 3.             All

intentionally radiating elements that are not fixed-mounted in use are placed on the test table lying flat, on their
side, and on their end (3-axes) and the resulting worst case emissions are recorded. If the EUT is fixed-mounted in
use, measurements are made with the device oriented in the manner consistent with installation and then emissions
are recorded.
    If the EUT exhibits spurious emissions due to internal receiver circuitry, such emissions are measured with an
appropriate carrier signal applied. For devices with intentional emissions below 30 MHz, a shielded loop antenna
is used as the test antenna. It is placed at a 1 meter receive height and appropriate low frequency magnetic field
extrapolation to the regulatory limit distance is employed. Emissions between 30 MHz and 1 GHz are measured
using tuned dipoles and/or calibrated broadband antennas. For both horizontal and vertical polarizations, the test
antenna is raised and lowered from 1 to 4 m in height until a maximum emission level is detected. The EUT is
then rotated through 360o in azimuth until the highest emission is detected. The test antenna is then raised and
lowered one last time from 1 to 4 m and the worst case value is recorded. Emissions above 1 GHz are characterized
using standard gain horn antennas or calibrated broadband ridge-horn antennas on our OATS with a 2.4m x 2.4m
square of AN-79 absorber placed over the ground screen between the EUT and the test antenna. Care is taken to
ensure that test receiver resolution and video bandwidths meet the regulatory requirements, and that the emission
bandwidth of the EUT is not reduced. Photographs of the test setup employed are depicted in Figure 4.
    Where regulations allow for direct measurement of field strength, power values (dBm) measured on the test
receiver / analyzer are converted to dBµV/m at the regulatory distance, using

                                         Edist = 107 + PR + KA − KG + KE − CF

where PR is the power recorded on spectrum analyzer, in dBm, KA is the test antenna factor in dB/m, KG is the
combined pre-amplifier gain and cable loss in dB, KE is duty correction factor (when applicable) in dB, and CF is

a distance conversion (employed only if limits are specified at alternate distance) in dB. This field strength value is
then compared with the regulatory limit. If effective isotropic radiated power (EIRP) is compute, it is computed as

                                           EIRP (dBm) = E3m (dBµV /m) − 95.2.

When presenting data at each frequency, the highest measured emission under all possible EUT orientations (3-axes)
is reported.

3.1.2   Conducted Emissions Test Setup and Procedures
Battery Power Conducted Spurious The EUT is not subject to measurement of power line conducted emissions
as it is powered solely by its internal battery.

3.1.3   Power Supply Variation
Tests at extreme supply voltages are made if required by the the procedures specified in the test standard, and results
of this testing are detailed in this report.
    In the case the EUT is designed for operation from a battery power source, the extreme test voltages are evaluated
over the range specified in the test standard; no less than ±10% of the nominal battery voltage declared by the
manufacturer. For all battery operated equipment, worst case intentional and spurious emissions are re-checked
employing a new (fully charged) battery.

3.1.4   Thermal Variation
Tests at extreme temperatures are made if required by the procedures specified in the test standard, and results
of this testing are detailed in this report. The provider has declared that the EUT is designed for operation over
the temperature range Not Declared. Before any temperature measurements are made, the equipment is allowed to
reach a thermal balance in the test chamber, temperature and humidity are recorded, and thermal balance is verified
via a thermocouple based probe.

3.2.2   Fundamental Emission Bandwidth
Emission bandwidth (EBW) of the EUT is measured with the device placed in the test mode(s) with the shortest
available frame length and minimum frame spacing. Radiated emissions are recorded following the test procedures
listed in Section 1.1. The 20 dB EBW is measured as the max-held peak-detected signal when the IF bandwidth
is greater than or equal to 1% of the receiver span. For complex modulations other than ASK and FSK, the 99%
emission bandwidth per IC test procedures has a different result, and is also separately reported.The results of EBW
testing are summarized in Table 4. Plots showing measurements employed to obtain the emission bandwidth reported
are provided in Figure 6.
