Specifications (5) popup

The NI USB noise, vibration, and harshness (NVH) system is a complete sound and vibration solution for NVH, acoustics, electroacoustics, vibration, and structural dynamics. Applications include the following:

  • Spherical beamforming
  • Spiral microphone arrays
  • In-vehicle NVH test
  • In-vehicle system dynamics
  • Vehicle pass-by
  • Noise source identification
  • Manufacturing test
  • Structural test
  • Structural monitoring

Software

The NI USB NVH system comes with easy-to-use software, the NI Sound and Vibration Measurement Suite, which is the most comprehensive collection of NI analysis and signal processing tools for NVH. It contains analysis functions including octave analysis, spectral analysis, level measurements, swept sine, JTFA, and order analysis.

Hardware

The NI USB NVH system features from four to 32 accelerometer/microphone input channels. The accelerometer/microphone channels offer software-selectable IEPE signal conditioning, 24-bit resolution, 102 dB dynamic range, 51.2 kS/s maximum simultaneous sampling, and antialiasing filters. The system also offers mixed-measurement capability for temperature, strain, voltage, and other process variables.

The NI USB NVH system is based on the NI CompactDAQ platform, which provides the plug-and-play simplicity of USB to sensor and electrical measurements on the benchtop, in the field, and on the production line. By combining the ease of use and low cost of a data logger with the performance and flexibility of modular instrumentation, NI CompactDAQ delivers fast and accurate measurements in a small, simple, and affordable system.
