Noise and vibration analysis - NVH

With the NVH analysis software, imc WAVE, and imc measurement devices, you have powerful tools for noise and vibration analysis at your disposal. Ready-to-go analysis functions such as FFT, order tracking, modal analysis, third-octave analysis and many more will provide finished results. imc devices calculate the results already during the running measurement and help to reduce data down to the essentials. Complete analysis packages offer less-experienced users in the field of NVH a safe and straightforward operation. In addition to noise and vibration analysis, imc measurement devices can realize many other measurements, such as temperature, power or strain gauge. In this way, imc can offer you a complete test & measurement solution from a single source.
