AN616 Si4010/Si4313 DEMO LINK RF E M I S S I O N /I MMUN IT Y TEST REPORT A CCORDING TO EN 55025 AND GS 95002 1. Introduction This document contains a complete test report that describes the RF Emission and RF Immunity tests that were performed on a Silicon Labs Si4010-Si4313 demo RF link. An RF emission and RF immunity test was performed in a third party independent accredited test laboratory to demonstrate, that Silicon Laboratories' Si4010 crystal-less SoC RF transmitter and Si4313 low-cost ISM receiver is capable to constitute an RF link for automotive applications, that meets the requirements of EN 55025 and GS 95002 standards. The tested equipments were as follows: Si4010 Universal Key Fob 434 MHz (S/N 4010-DAPB_434) and Si4343 LED receiver board low band pcb ant (S/N 4313-DAPB_LB) The boards are available from Silicon Laboratories as part of the Si4010 Simplified Key Fob Demo Kit 434 MHz (S/N 4010-DASKF_434). The tested equipments passed all the tests described in detail in the appended test report. For technical details on the tested ICs, boards, and demo kits visit http://www.silabs.com.
