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.
