The test and application are submitted for an Intentional Radiator under Part 15.209 of the FCC Rules and Regulations. The Equipment Under Test was the Lucas Automotive Electronics Low Power Transceiver. All measurements herein were performed according to the 1992 version of ANSI C63.4. The measurement equipment conforms to ANSI C63.2 Specifications for Electromagnetic Noise and field Strength Instrumentation. Calibration checks are made periodically to verify proper performance of the measuring instrumentation. All measurements are performed at Washington Laboratories, Ltd. test center in Gaithersburg, MD. Site description and site attenuation data have been placed on file with the FCC's Sampling and Measurements Branch at the FCC laboratory in Columbia, MD. Washington Laboratories, LTD. has been accepted by the FCC and approved by NIST NVLAP (NVLAP Lab Code: 200066-0) as an independent FCC test laboratory. All results reported herein relate only to the equipment tested. The measurement uncertainty of the data contained herein is ± 2.3 dB. Refer to Appendix A for Statement of Measurement Uncertainty. This report shall not be used to claim product endorsement by NVLAP or any agency of the US Government. 1.1Summary The Lucas Automotive Electronics Transceiver complies with the limits for an Intentional Radiator under Section 15.209. 2.0Description of Equipment Under Test (EUT) The Lucas Automotive Electronics 35AS Immobilizer System is a 125 kHz low power transceiver that is used as a theft deterrent ignition system switch used in automobiles. The 35AS consists of an energizer coil and an immobilizer unit. The energizer coil is fitted to the end of the ignition lock key barrel of the vehicle and the immobilizer unit is mounted in the vehicle fascia. The energizer coil is connected to the immobilizer unit via twisted pair wiring. The immobilizer communicates with the transponder which is mounted in the handle of the vehicle ignition key. With the ignition turned on, the oscillator in the immobilizer unit drives the energizer coil to produce a 125 kHz electromagnetic field which activates the transponder. The transponder and immobilizer exchange data and if the transponder identity is recognized by the immobilizer and the immobilizer identity is recognized be the engine management unit the engine is allowed to run, otherwise the engine is stopped. 2.1On-board Oscillators The Lucas Automotive Electronics 35AS Immobilizer System contains a 4 MHz oscillator and a single chip transceiver which uses an inductor and capacitor to provide a 125 kHz resonant circuit. Lucas Automotive Electronics FCC ID: KHH35AS WLL Project # 4709X 3.0Test Configuration To complete the test configuration required by the FCC, the 35AS Immobilizer transceiver was mounted on a vehicle ignition key barrel and a key was placed in the ignition tom modulate the carrier. The ignition barrel was placed in the horizontal plane in order to simulate “normal” installation in a vehicle. Unshielded wires were connected to the unit to simulate connection to the vehicle wiring. During emissions testing, 14.4 VDC was applied via a bench power supply to simulate a car vehicle battery with a key installed into the switch. 3.1Testing Algorithm The transceiver was turned on and modulated by the transponder in the key. Worst case emissions are recorded in the data tables. 3.2Conducted Emissions Testing Conducted emissions testing was not performed as the EUT is battery powered. 3.3Radiated Emissions Testing The EUT was placed on an 80 cm high 1 x 1.5 meters non-conductive motorized turntable for radiated testing on a 3 meter open field test site. The emissions from the EUT were measured continuously at every azimuth by rotating the turntable. Biconical, log periodic and rod antennas were mounted on an antenna mast to determine the height of maximum emissions. The height of the antenna was varied between 1 and 4 meters. The peripherals were placed on the table in accordance with ANSI C63.4-1992. Cables were varied in position to produce maximum emissions. Both the horizontal and vertical field components were measured. The output from the antenna was connected, via a preamplifier, to the input of the spectrum analyzer. The detector function was set to quasi-peak or peak, as appropriate. For emissions above 30 MHz, the measurement bandwidth on the spectrum analyzer system was set to at least 120 kHz, with all post-detector filtering no less than 10 times the measurement bandwidth. For emissions below 30 MHz, the measurement bandwidth on the spectrum analyzer system was set to at least 9 kHz, with all post-detector filtering no less than 10 times the measurement bandwidth.
