Abstract

The existing failure analysis (FA) tool used in the manufacturing was unable to support multiple input multiple output (MIMO) analysis and it has poor user interface capability. The tool used by hardware engineers and design engineers is capable for all radio frequency (RF) analysis including MIMO, but yet it is an extremely expensive tool with rigid interface due to the need for automation. Wireless advanced FA tool (WAFT) was then designed, developed, and deployed as a single solution to FA engineers to perform all the RF analysis including MIMO in a user friendly interface and affordable setup. This article provides information on design planning, application, validation, and deployment of WAFT as well as on transmit quality and receive quality evaluation. WAFT has been validated in providing accurate measurement by benchmarking with the existing tools. WAFT provides the interactive controllability and comprehensive signal analysis capability including MIMO needed for FA.
