This paper introduces a nonparametric, nonlinear system identification toolbox called SAMI (simplified analysis for multiple input systems) developed for industrial measurements of vibro-acoustic systems with multiple inputs. It addresses the questions related to the user-friendly (semi-)automatic processing of multiple-input, multiple-output measurements with respect to the design of an experiment and the analysis of the measured data. When the proposed toolbox is used, with minimal user interaction, it is easily possible (a) to decide whether the underlying system is linear or not, (b) to decide whether the linear framework is still adequate to be used, and (c) to tell an inexperienced user how much can be gained using an advanced nonlinear framework. The toolbox is illustrated on openly accessible F-16 ground vibration testing measurements.

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.
