The X-FEM NVH is a 4-channel acquisition module suitable for use with all common acoustic sensor output types such as voltage, charge and ICP/IEPE. Each channel can be individually configured.
All raw signals are stored in a compressed file at high resolution and in time-synchronized formats. The signals and relevant KPI’s are available in real-time and can be transmitted to an automation system or optimization software for further processing.
The optional NVH TOOLBOX for AVL IndiCom™ or AVL Concerto™ includes the most common NVH analysis tools and online NVH macros, which significantly accelerates and simplifies both data acquisition and subsequent data evaluation.

X-FEM NVH
The X-ion Front-End Modules – or X-FEM – enable smart modularity and ensure AVL X-ion is a perfect match for each application.
HIGH ACCURACY
The NVH module has four inputs for microphones or accelerometers (IEPE/ICP or charge sensors) and offers a resolution of 24 bit with a sampling rate of up to 500 kS/s.
Software for NVH Analysis
The AVL NVH Toolbox with its embedded online NVH Macros enables the online acquisition and real-time KPI evaluation of acoustic and vibration signals and also provides a basic toolkit for offline NVH measurement data analysis.
