Configure Page for: Print PDF Rich Text
  • Not recommended for new designs. NI recommends the NI PXIe-4492.
  • Life-cycle status: Mature
  • ±10 V input range or ±31 V with SMB-120 cable
  • Eight simultaneously sampled vibration-optimized analog inputs at up to 102.4 kS/s
  • Software-configurable AC/DC coupling and IEPE conditioning
  • 24-bit resolution ADCs with 110 dB dynamic range


The NI PXI-4472B, an extension of the NI 4472 family, is optimized for vibration and low-frequency AC measurements. It provides 8-channel dynamic signal acquisition for making high-accuracy frequency-domain measurements. Input channels incorporate integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones. The eight input channels of the PXI-4472B simultaneously digitize input signals over a bandwidth from DC to 45 kHz. The PXI-4472B features a cutoff of only 0.5 Hz when the device is AC-coupled for very low-frequency AC vibration measurements.

Best Value: Buy Both and Save
The PXI-4472B is also available as a bundle with the NI Sound and Vibration Measurement Suite, which includes the 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 Sound and Vibration Measurement Suite and the 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 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, the Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
