Designed to test the full specification of the Cordless Kitchen developed by the WPC
___________
Cost-effective system for wireless power product design and interoperability testing
MEET THE EVA III
EVA III is the first comprehensive set of evaluation and compliance tools designed for performance testing and evaluation of wireless power devices within the emerging Cordless Kitchen specification from the Wireless Power Consortium (WPC).The EVA III system includes two primary units: the Base Station Tester (BST), with separate load boxes to test a transmitter, and the Mobile Device Tester (MDT) to test a receiver. In addition to this core configuration, the system connects to a host computer via a USB connection, and it features a dynamic user interface that provides adjustable settings and parameters to fit individual product development and evaluation needs.
