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.

During the measurements with RX and TX together the receiver stops working in the frequency
range between 428,5 and 437,5 MHz.
During the measurement with TX alone (the transmitter signal was coupled via antennas to the
receiver outside of the chamber) the receiver stops working between 431,5 and 433,5 MHz.
