The National Instruments PXI-4472B, an extension of the NI 4472 family, is optimized for vibration and low-frequency AC measurements. The NI PXI-4472B provides eight-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 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.
Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:
Installation and integration test of all individual hardware
Courtesy installation of system driver sets and application development environments
Extended warranty and calibration coverage for up to five years
Custom documentation plus a custom restore and startup utility
This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.
National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:
Significant cost savings compared to individual repair incidents
Fault location, diagnostics, and repair by NI any time the system product fails
All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications
NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.
Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
