With its associated tire sensors and receiver; the initiator is part of the system used to detect the tire pressure of the tires in a vehicle. Four initiators are used in each vehicle, one for each tire. They are located in or near the wheel well and are connected by wire harness to the central receiver (FCC ID:GQ4- 3QR). This central receiver sends a 125KHz waveform over the wire harness to the initiator where it is converted to a magnetic field that is broadcast to a sensor in the tire. The tire sensor then responds by transmitting a 315MHz signal back to the receiver, closing the loop. With warning lights on the dashboard, the receiver informs the driver when the air pressure in a certain tire is low. The initiator consists of one printed circuit board housed in a plastic case. Embedded in the plastic case is a low frequency ferrite antenna. A three-pin connector molded into the plastic case is used to connect the wire harness from the receiver.

Input comparator circuitry clean this waveform up where it is level shifted and timing shifted to avoid shoot through currents in the output push/pull transistor stage. The push/pull transistor stage drives a tank circuit tuned to approximately 125KHz and the inductor in the tank circuit is the magnetic transducer used to broadcast a signal to the tire sensor.

Courtney Report approved by: _____________________ Valdis V. LiepaValdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations, Part 15, Subpart C, and for compliance with Industry Canada RSS-210, were performed on TRW, Inc. transmitter, model 39360-S9V-A0. This device is subject to Rules and Regulations as a transmitter. In testing completed 20-May-04, the device tested in the worst case met the allowed specifications for transmitter radiated emissions by 51.9 dB (see p. 7); digital emissions, Class B, were met by at least 20 dB. The conducted emissions tests do not apply, since the device is powered from a 12 VDC system. 2 1. Introduction TRW model 39360-S9V-A0 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210, Issue 5, November, 2001. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-1992 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057). 2. Test Procedures and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.
