Raditeq – Creating Turnkey EMC Test Solutions
Philips Consumer Lifestyle located in Drachten, the Netherlands, develops and produces Health and Lifestyle products with the aim to improve healthy diets and a health life. Examples of these products are the SensoTouch 3D Shaver, Senseo Coffee machines, the SoniCare dental hygiene products and the AirFryer with needs no deep fat to operate.
Philips previously owned a compact but fully anechoic chamber (CFAR) and a Radiated Immunity (RI) test system. This system operated up to 1 GHz and made use of the automated EMC software RadiMation. To able to adhere to all the Standards and Directives needed for consumer electronics, they needed to upgrade their system to be able to perform tests from 80 MHz up to 6 GHz.
Philips’s CFAR was originally equipped with ferrite tiles which do not work as absorbers above 1 GHz. To be able to reach up to the 6 GHz, they needed to upgrade their room with absorbers that would do the job! Therefore, their chamber was equipped and upgraded with the ETS-Lindgren™ hybrid absorbers – FerroSorb™.
Philips already owned a existing RI system which was capable to measure up to 1 GHz. This system was installed in a 19-inch rack with separate equipment from different brand. The 19-inch rack is equipped with a Signal generator, RF power meter, an amplifier and finally the RadiSense® 4 GHz E-Field Probe.
The only thing which was kept for the upgraded system was the amplifier covering 80 MHz to 1 GHz and everything else was replaced. This was achieved by a single RadiCentre® 9-slot multifunctional modular test system with multiple integrated devices. The integrated equipment consists of a RadiGen® 6 GHz Signal Generator, a RadiSwitch® Coaxial switch cards and the RadiSense® 6 LASER powered E-Field Probe.
Electric Field Generation – Radiated Immunity
The RI system above the 1GHz was replace by the efficient Electric Field generator – The RadiField® which was introduced in 2014 by Raditeq (DARE!! Instruments at the time) as the world’s first and only E-Field Generator. This device can create extremely efficient fields from 800 MHz up to 6 GHz. At a 3-meter distance from the EUT the RadiField® can create fields up to 18 V/m. This field level increases the closer you place the RadiField® to the EUT! The RadiField® can create fields up to 54 V/m at 1-m distance! The Electric Field generator simplifies the RI conventional system by combining and integrating, amplifiers, directional couplers, forward- and reflected power meters and antennas in one single unit.
The integration and simplification make the RadiField® not only cost effective in the initial purchase but also more effective and efficient in the power consumption of your RI system lowering the costs all around the board! The RadiField® is controlled and powered by one N-type cable which is connected to the RadiField® power supply in the RadiCentre® making the complete Radiated Immunity test system operated from the RadiCentre®.
The Radiated Emission part of the system is completed by the ETS-Lindgren™ 3142A Antenna to perform emission measurements up to 6 GHz. This same antenna is also used for immunity testing from 80 MHz to 1 GHz.
By applying the hybrid absorbers in the anechoic chamber, it has become less spacious and therefore the small and flexible ETS-Lindgren™ was chosen to be able to still be able to move around freely in the chamber.
By combining the Radiated Immunity and Emission in one chamber the RadiMation® automated software can control both tests and control masts and turntables making the complete EMC test system fully automated.
Still in use!
The RadiField® was delivered in 2015 and is still in operation at Philips consumer Lifestyle at this moment. This makes the RadiField® and ideal long time RI solution.
