Keysight and SmartViser enable testing in accordance with the EU Energy Labeling Regulation

  • The joint solution tests the energy efficiency of smartphones and tablets to meet labeling requirements

  • The solution enables designers to use SmartViser viSer software with any Keysight UXM 5G wireless test platform configuration to determine a device’s energy efficiency index

SANTA ROSA, California, June 11, 2024–(BUSINESS WIRE)–Keysight Technologies, Inc. (NYSE: KEYS) and SmartViser have joined forces to provide device manufacturers with a solution to test the Energy Efficiency Index (EEI) of smartphones and tablets for compliance with European Union energy label mandates. With this common solution, SmartViser viSer test automation software for mobile devices can be used with any configuration of the Keysight UXM 5G wireless test platform.

Pursuant to Delegated Regulation (EU) 2023/1669, all smartphones and tablets sold in the EU after 20 June 2025 must bear an EEI label. To meet this EU requirement, manufacturers must test these devices using the procedures described in the regulation to determine the battery consumption rate. However, device manufacturers need a plug-and-play EEI testing solution that works with their existing test setups.

To meet this need, Keysight and SmartViser have validated the integration of both platforms to enable users of the UXM 5G wireless test platform to use viSer software to perform an automated test to accurately assess device battery usage.

The Keysight UXM 5G wireless test solution is a highly integrated signaling test platform with multi-format stack support, high processing power and large radio frequency (RF) resources. Supporting 3GPP version 15 and above, the UXM 5G wireless test solution enables engineers to establish a 5G connection to the device under test in a variety of new 5G radio deployment modes. It also supports LTE, eMTC, Wi-Fi®and C-V2X signaling formats.

Gilles Ricordel, CEO of SmartViser, said: “From 2021, SmartViser is working closely with EU authorities and policymakers to establish EEI verification criteria on smartphones and Slate tablets, and SmartViser proposes the viSer app to meet such testing requirements. Integrating viSer with the Keysight UXM 5G wireless test setup allows us to meet the needs of the cellular ecosystem using Keysight for device testing.”

Muthu Kumaran, General Manager, Device Acceptance Solutions, Keysight, said: “Working with SmartViser allows us to continue to add value to our customers’ hardware investments by providing valuable new features. With a quick update, device manufacturers can immediately start conducting EEI testing to meet EU labeling regulations for equipment they already have. on its test bench, this will not only help device manufacturers achieve superior performance that influences consumer preferences for their products, but also address key sustainability challenges. As a company, we are pleased to facilitate these tests.
