NATIONAL Instruments has announced the NI Sound and Vibration Measurement Suite Version 6.0 and the newest 16-channel data acquisition module for sound and vibration, the NI PXI-4495.
The Suite 6.0 is a comprehensive collection of analysis and signal processing tools for noise, vibration and harshness (NVH); machine condition monitoring (MCM); and audio test applications.
It includes both the NI Sound and Vibration Assistant 6.0, application software that combines interactive, configurable data acquisition, analysis and data logging, and NI LabVIEW analysis VIs.
The new version extends sound and vibration measurement capability with order analysis support in the Sound and Vibration Assistant and new LabVIEW VIs for torsional vibration measurement and human vibration weighting filters.
In addition, the 16-channel, 24-bit, dc-coupled PXI-4495 complements the PXI-4496 and PXI-4498 high-channel-count dynamic signal acquisition (DSA) modules.
The Sound and Vibration Assistant is designed to simplify the process of acquiring and analysing noise and vibration signals by offering a stand-alone, interactive analysis and acquisition environment.
The stand-alone software offers a way to continually interact with varying data analysis settings while logging data to disk for more analysis later.
For example, engineers can vary the weighting and bandwidth of an octave spectrum while recording sound-level data or adjust the window applied to a power spectrum while recording overall vibration readings.
In addition, the software makes it possible to share acquired signals and analysis results with other applications through universal file format (UFF) file I/O support.
It also includes analysis features for NVH, MCM and audio test applications. The assistant also provides analysis functions such as power spectrum, octave analysis, frequency response, sound and vibration level, tachometer processing, order analysis and order tracking.
