Hardware Platforms Overview
With National Instruments sound and vibration measurement hardware, you have the flexibility to create a wide variety of custom automated measurement systems on industry-standard computer platforms. NI dynamic signal acquisition (DSA) devices are designed specifically for applications requiring audio, noise, and vibration measurements. They can acquire and generate signals at sampling rates up to 204.8 kS/s with 24-bit resolution complete with NIST-traceable calibration certificates, up to 118 dB dynamic range, with AC/DC coupling, IEPE conditioning, anti-aliasing filters, and TEDS.
Options are available to build systems that synchronize acquisition on up to 10,000 channels of signals, such as accelerometers and microphones. You can synchronize NI DSA devices with less than 0.1 deg phase mismatch between channels.
Analysis Software and Libraries
National Instruments sound and vibration analysis software, including the NI Sound and Vibration Measurement Suite, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, order tracking, and human vibration weighting. NI sound and vibration software also features the NI Sound and Vibration Assistant - interactive software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data.
