The National Instruments PCI-4472B, an extension of the NI 4472 family, is optimized for vibration and low-frequency AC measurements. The NI PCI-4472B provides eight-channel dynamic signal acquisition (DSA) for making high-accuracy frequency-domain measurements. Input channels incorporate integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones. The eight PCI-4472B input channels simultaneously digitize input signals over a bandwidth from DC to 45 kHz. The PCI-4472B features a cutoff of only 0.5 Hz when the board is AC-coupled for very low-frequency AC vibration measurements.
Best Value: Buy both and save. The PCI-4472B is also available as a bundle with the NI Sound and Vibration Measurement Suite, which includes NI Sound and Vibration Assistant, at a discount from the list price. See the Resources tab for more information on the list of analysis capabilities in the Sound and Vibration Measurement Suite.
Multidevice Synchronization For applications requiring up to thousands of channels, you can synchronize the operation of two or more NI 447x devices with less than 0.1 deg of phase mismatch between channels.
Recommended Software NI sound and vibration analysis software, including the NI Sound and Vibration Measurement Suite and the NI Sound and Vibration Toolkit, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. NI analysis software features NI Sound and Vibration Assistant interactive software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data. With a configuration-based, flexible measurement library and open-analysis capability, Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
