APPLICATION FOR CERTIFICATION INTENTIONAL RADIATOR UNDER 47 CFR, PART 15.231(e) SmarTire Systems, Inc. FCC ID: NATTX433VM JUNE 28, 2000 Prepared By: Spectrum Technology, Inc. 209 Dayton Street Edmonds, WA 98020 CERTIFICATION TABLE OF CONTENTS Field Strength of Radiated Emissions Setup and Discussion 1 - 2 Tabular Field Strength Results under Part 15.2313 - 4 Antenna Factors and Sample Calculations 5 - 8 Test Equipment List9 TEST: FIELD STRENGTH OF RADIATED EMISSIONS Grantee:SmarTire Systems, Inc. FCC ID: NATTX433VM Setup: The equipment under test (EUT) was configured and operated in accordance with the applicable provisions of ANSI C63.4-1992, Section 6, 13. Measurements were made in accordance with applicable paragraphs of Section 8.2.3, 8.2.4, Section 13.1.1, 13.1.4 Appendix D, and I. The EUT was placed on a 1 by 1.5 meter table located 40 cm above a 2 meter diameter non-metallic turntable that sits 40 cm above the 15 X 30-meter ground plane at Spectrum's Open Area Test Site. The bi-conical or log-periodic antenna was mounted on a tower spaced at a three meters distance, and arranged for adjustment in height (1-4 meters) and vertical/horizontal polarization to maximize the emissions levels when combined with turntable rotation of the EUT. The dual ridged guide antenna was mounted on a tripod at one-meter height and adjusted for vertical or horizontal antenna orientation. An HP 8562A spectrum analyzer with an HP 8447F, Option H64 amplifier and an HP 83006A pre- amplifier were used for the measuring instrumentation. Discussion: No modifications required for compliance prior to the final radiated emissions measurements reported herein. The EUT is the transmitter for the Smartire Passenger Car Monitoring System which uses four 433 MHz transmitter sensors. A 433 MHz receiver used in the SmartTire Passenger Car Tire Monitoring system would be installed in a passenger vehicle and used to receive signals and display status of passenger tire pressure sensors installed on the wheels. The transmitter and sensor would be mounted at the base of the valve stem on each of the four wheels. Each transmitter reports back to the receiver approximately every four to six minutes continuously with pressure and temperature status. If a reduction in pressure is sensed the sensor will transmit more frequently. The information being considered a safety issue, as in the case of a punctured tire and an alarm is displayed on the receiver. The EUT would be installed as the valve stem for a standard automotive steel wheel rim with typical steel belted radial passenger tire mounted. For the radiated emissions test, the transmitter was set on the table and tested while positioned in three orthogonal planes. The position with the valve stem positioned up was observed to be the worst case by a small margin and is reported herein. The EUT was carefully centered on the table to maintain a 3-meter distance during rotation. The radiated tests were conducted this way based on correspondence previous correspondence for the lab requiring testing the EUT off the rim.Page 1 The transmitter was jumpered with two leads brought out externally to allow continuous repetitive transmission at its maximum date rate. This made it much more convenient to observe maximum emission levels when the turntable was rotated and antenna height and polarization adjusted. Measurements were made for the single frequency AM pulse modulated intentional radiator operating at its nominal operating frequency 433 MHz =/- 75 kHz. Preliminary measurements were made as described in Section 8.3.11 and 13.1.4.1 with the EUT operating as described. The final set of measurements as specified in Section 8.3.1.2 and 13.1.4.2 were made as specified in Section 13.1.1. The transmitter was observed stand alone while positioned on the turntable three meters from the receive antenna. We rotated the turntable and varied antenna height and polarization endeavoring to maximize the signal being measured. The EUT was powered with a new battery during the measurements. RBW and VBW of 100 kHz were used for measurements below 1 GHz. Above 1 GHz peak measurements were made with a RBW and VBW of 1 MHz. Most of the harmonics through 10 Fo were measurable at 3 meters during the final detailed radiated emissions measurements. An HP pre-amplifier was used along with a band pass filter to attenuated the 433 MHz signal and avoid overloading the front end of the spectrum analyzer. Conclusion: The SmarTire Systems, Inc., FCC ID: NATTX433VM, when operated and measured as discussed above, complies with the field strength of the fundamental limit and limits for spurious emissions requirements under Title 47, CFR Part 15.232(e). Duty cycle averaging is applied to the peak reading to comply with the average limit. This device has shown compliance with the current rules and is not subject to the transition provisions of Part 15.37. Page 2 SPECTRUM TECHNOLOGY, INC.
