No. 1.1, 05.11.2008 2 S U M M A R Y GENERAL REMARKS: All tests have been performed on samples (TSSRE3Db_Gen3.4) which are in original state. Partly tests have been repeated on samples (TSSRE3Dc_Gen3.5) which are in original state to establish the equality. For activating the EuT a “Beru TSS Tester” was used. With this device it is possible to set the EuT in all operation modes. There are two different types of housing “TSSRE3Db_Gen3.4” and “TSSRE3Dc_Gen3.5”. The PCB, Battery and all other parts are technical identical. The EUT has an incorporated antenna and is powered by a primary battery. The manufacturer declares following transmitting intervals: - Normal Operation mode: In normal operation mode, the wheel electronic transmits every 30s (a random generator with a jitter of 25ms to 175ms ensures that no periodic signal is generated) data messages. Tire pressure and wheel electronics temperature are also measured every 3 seconds. - Fast send mode: When a pressure loss > 0.2 bar/min on the last transmitted pressure value is detected, the wheel electronic jumps into the alarm mode where the pressure is measured and transmitted every second. With a length of approx. 10msec the RF telegram is t ransmitted 255 times. Within a 4 minute time period, even under bad transmit conditions, a detection of apressure loss of 0.8 bar is guaranteed. Assuming a typical tire pressure of 2.2 bar and a pressure loss of 0.8 bar within a 4 minute time period, the critical wheel pressure P Warning Minimum Pressure (= 1.4 bar) is reached. FINAL ASSESSMENT: The equipment under test fulfills the EMI requirements cited in clause 1 test standards. Date of receipt of test sample : acc. to storage records Testing commenced on : 24.

Field strength of the fundamental wave For test instruments and accessories used see section 6 Part CPR 2. 1.1.1 Description of the test location Test location: OATS1 Test distance: 3 metres 1.1.2 Photo documentation of the test set-up 1.1.1 Applicable standard According to FCC Part 15C, Section 15.231(e): The field strength of emissions from intentional radiators shall not exceed the effective field strength limits. 1.1.2 Description of Measurement The radiated power of the fundamental wave from the EUT is measured in the frequency range of 30 to 1000 MHz using a tuned receiver and appropriate broadband linearly polarized antennas. Measurements between 30 MHz and 1000 MHz are made with 120 kHz/6 dB bandwidth and quasi-peak detection. Table top equipment is placed on a 1.0 X 1.5 metres non-conducting table 80 centimetres above the ground plane. Floor standing equipment is placed directly on the turntable/ground plane. The set up of the EUT will be in accordance to ANSI C63.4. The Interface cables that are closer than 40 centimetres to the ground plane are bundled in the centre in a serpentine fashion so they are at least 40 centimetres from the ground plane. Cables to simulators/testers (if used in this test) are routed through the centre of the table and to a screen room located outside the test area. The antenna was positioned 3, 10 or 30 metres horizontally from the EUT. To locate maximum emissions from the test sample the antenna is varied in height from 1 to 4 metres, measurement scans are made in horizontal and vertical antenna polarization’s and the EUT is rotated 360 degrees. Spurious emissions (magnetic field) 9 kHz – 30 MHz For test instruments and accessories used see section 6 Part SER 1. 1.1.3 Description of the test location Test location: OATS1 Test distance: 3 metres 1.1.4 Photo documentation of the test set-up 1.1.5 Applicable standard According to FCC Part 15C, Section 15.209: The emissions from intentional radiators shall not exceed the effective field strength limits. 1.1.6 Description of Measurement The magnetic field strength from the EUT will be measured on an open area test site in the frequency range of 9 kHz to 30 MHz using a tuned receiver and a shielded loop antenna. The set up of the Equipment under test will be in accordance to ANSI C63.4. The antenna was positioned 3, 10 or 30 meters horizontally from the EUT. Measurements have been made in all three orthogonal axes and the shielded loop antenna was rotated to locate the maximum of the emissions. In the case where larger measuring distances are required the results will extrapolated based on the values measured on the closer distances according to Section 15.31(f)(2)(2). The final measurement will be performed with an EMI Receiver set to Quasi Peak detector except for the frequency bands 9 kHz to 90 kHz and 110 to 490 kHz where an average detector will be used according to Section 15.209(d)(2). Spurious emissions radiated (electric field) For test instruments and accessories used see section 6 Part SER 2, SER 3. 1.1.7 Description of the test location Test location: OATS1 Anechoic Chamber A2 Test distance: 3 metres 1.1.8 Photo documentation of the test set-up Correction for pulse operation (duty cycle) For test instruments and accessories used see section 6 Part DC. 1.1.9 Description of the test location Test location: AREA4 1.1.10 Photo documentation of the test set-up 1.1.11 Applicable standard According to FCC Part 15C, Section 15.35(c): The emissions from intentional radiators shall not exceed the effective field strength limits. 1.1.12 Test result The Duty cycle factor (dB) is calculated applying the following formula: KE= 20 log ((tiB)/100) KE: pulse operation correction factor (dB) tiB pulse duration for one pulse (ms) Maximum transmitting duration in every 100ms period: KE= 20 log ((5.568)/100) = -20.0 dB Remarks: Emission bandwidth For test instruments and accessories used see section 6 Part MB. 1.1.13 Description of the test location Test location: AREA4 1.1.14 Photo documentation of the test set-up 1.1.15 Applicable standard According to FCC Part 15C, Section 15.231(c): The bandwidth of the emission shall not exceed the effective limits. 1.1.16 Description of Measurement The measurement was performed conducted with intentional modulation using a spectrum analyser. The analyser span was set wide enough to capture the most of the power envelope of the signal. The function “20-dB-down” is used to determine the BW. For an overview on the adjacent restricted bands the span was set as wide as needed to show that the restricted bands are not affected. On / Off Period For test instruments and accessories used see section 6 Part MB. 1.1.17 Description of the test location Test location: AREA4 1.1.18 Photo documentation of the test set-up 1.1.19 Applicable standard According to FCC Part 15C, Section 15.231(e): 1.1.20 Description of Measurement The duration of transmission is measured with the spectrum analyzer. The sweep points were set to maximum for higher the time resolution. The signal is modulated; the marker of the analyzer is set to maximum amplitude at normal temperature and zero span. The analyser was set to single sweep and triggered on the button, the marker was set to the edges in order to measure the duration time and than recorded. Signal deactivation For test instruments and accessories used see section 6 Part MB. 1.1.21 Description of the test location Test location: AREA4 1.1.22 Photo documentation of the test set-up 1.1.23 Applicable standard According to FCC Part 15C, Section 15.231(a): 1.1.24 Description of Measurement The duration of transmission is measured with the spectrum analyzer.
