The transmitter has the following sections: - RF circuit - Pressure sensor - roll switch - Transponder Coil (125kHz LF Learn Switch) - ASIC The system has been developed to monitor a vehicle's tyre pressures whilst driving or stationary. An electronic unit inside each tyre, (referred to as the RTPMS transmitter) mounted to the valve stem, periodically measures actual tyre pressure. By means of RF communication, this pressure information is transmitted to a receiver/decoder which is fitted in the car. The tire pressure value is detected by the ASIC (Application Specific Integrated Circuit) via a pressure sensor. The data is transmitted using a Manchester coding protocol at a maximum data rate of 4.096 Kbits/sec. The clock generator for the ASIC is crystal controlled. The block transmission format is shown in figure 2. The valve stem is part of the transmitting antenna. while the vehicle is parked (Stationary Mode), there is no transmission. when the vehicle is moving (roll switch closed) the RTPMS transmit each minute 8 words as shown in figure 2. The transmitter will remain in drive mode for a period of time known as the Service Period after the vehicle comes to rest (roll switch open). After the Service Period time has elapsed the transmitter returns to Stationary Mode. The RTPMS uses a Transponder Coil, which when activated with 125kHz LF, will ‘LEARN’ the ID code to the receiver/decoder in the production line of the vehicles.

The tests were performed at MIRA Ltd Open Area Test Site following the procedures described in ANSI C63.4-1992 “Methods of Measurements of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz’. The Schrader Electronics Ltd G3 Tyre 315 MHz Sensor Transmitter Models MRXNIS315G3 were received at MIRA on 24/03/05 and 15/09/05. Tests were performed on 16/03/05 (correction for pulse operation), 25/03/05 (emissions), 22/04/05 (emissions) and 30/09/05 (bandwidth and supply voltage variation). All equipment was returned to Schrader Electronics Ltd on 12/10/05. No representative was present to witness the testing, on behalf of Schrader Electronics Ltd. The site description and attenuation characteristics of MIRA Ltd Open Area Test Site are on file with FCC Laboratory, Columbia, Maryland, USA (registration number 877566). 2 Configuration and Equipment Under Test (EUT) Details The EUT is a 3.5 x 7.0 x 1.5 cm size (including value stem) potted tyre pressure sensor/transmitter that mounts on a rim inside the tyre. When the vehicle is in motion, the EUT transmits tyre pressure information to the receiver in the vehicle. The transmission consists of eight ASK and FSK encoded words of total duration of 0.928 seconds which repeat typically every 33 seconds. The 315 MHz carrier is generated by a SAW stabilised oscillator. The coding is performed by an ASCI timed by a 32.768 kHz crystal oscillator • Manufacturer Schrader Electronics Ltd • EUT ID: Schrader Remote Tyre Pressure Monitoring Transmitter • Model: MRXNIS315G3 • Serial Number: FCCGen3 • FCC ID: MRXNIS315G3 • MIRA IDs: E205-0225 (emissions), E205-0684 (bandwidth), E205-0225 (relative emissions) Three samples were provided. These were a continuous sample used to maximise the emissions; a standard sample for the emission and bandwidth measurements and a sample without a battery for the relative emissions verse battery voltage at 315 MHz. Schrader Electronics Ltd FCC Part 15 - Schrader Ltd G3 Tyre 315 MHz Sensor MIRA-1008842#01 Page 5 of 7 3 Radiated Emissions The radiated emissions tests were carried out on the Open Area Test Site (OATS) at MIRA in accordance with FCC Regulation 47, Subpart C, Section 15.231 and ANSI Standard C63.4- 1992 standard. 3.1 Test Method The EUT was tested as a standalone unit (i.e. not mounted on a tyre rim) The tests were performed on the EUT over the frequency range 30 MHz to the tenth harmonic of the EUT 315 MHz fundamental. This involved measuring the emissions from the EUT using an antenna, turntable and a receiver system. The EUT was placed on a 1 m by 1.5 m, 0.8 m table. Photographs showing the test configuration are shown in Appendix B. Tests were conducted using both the vertical and …
