CWTWCU11Part 15, Communications Receiver for use w/ Pt 15

User’s Manual MODEL No.: 28595EA The radio frequency keyless entry-TPMS system has the following functions. 1. Locking and unlocking the doors without mechanical key. 2. Sounding a panic alarm during vehicle is not running. 3. Tire-pressure data monitor by receiving RF signal from RF transmitter in tires during vehicle is running. This system consists of RF Tuner, transmitter, and BCM. The RF Tuner (EUT) is powered 5V from BCM. It is designed to operate on a single fixed frequency RF 315MHz by amplitude modulation. It receives unique identification code and function code transmitted from transmitter by pressing the button of the transmitter. After receiving RF signal, demodulation IC in Tuner demodulates RF signal from transmitter. And then driving circuit in Tuner outputs the demodulated signal to BCM.

But this frequency is used only in order for a mixer to generate the intermediate frequency of 10.7MHz. This digital part of EUT is operating in 65.13833MHz that is less than 108MHz. Therefore, the Spurious emission measurement for the upper frequency was up to 1GHz based on Section 15.33(b)(1). 3.3 Additions or deviations to standards No addition, deviation nor exclusion has been made from standards. 3.4 Confirmation UL Apex Co., Ltd. hereby confirms that E.U.T., in the configuration tested, complies with the specifications, FCC Part15 Subpart B : 2003. 3.5 Uncertainty Radiated Emission The measurement uncertainty (with a 95% confidence level) for this test using Biconical antenna is ±4.5dB(3m). The measurement uncertainty (with a 95% confidence level) for this test using Logperiodic antenna is ±5.2dB(3m). The data listed in this test report has enough margin. 3.6 Test Location UL Apex Co., Ltd. Head Office EMC Lab. No.2 semi anechoic chamber. 4383-326 Asama-cho, Ise-sh…
