No. 1.1, 05.11.2008 2 SUMMARY GENERAL REMARKS: All radiated tests have been performed on samples which are in original state. For activating the EuT a 125 kHz control signal was sent via “Beru TSS Tester”. With this function of the “Beru TSS Tester” it is possible to set the EuT in both operation modes. 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 electronic wheel unit measures the tire pressure and the approximate temperature of the air in the tire every three seconds but if the measured values are stable, sending processes are carried out only every 54 seconds. - Fast send mode: When a pressure loss > 0.2 bar on the last sent pressure value is detected, the wheel electronics switch immediately to fast-send mode. In this situation, the wheel electronics measure and send every 0.8 seconds for 255s. After this period of time it falls to the normal operation mode back. 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 : 11.

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.

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).
