The National Instruments PXI-4462 is a high-accuracy data acquisition module specifically designed for sound and vibration applications. This module includes the hardware and software needed to make precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. Common applications include audio test; automotive noise, vibration, and harshness (NVH); and machine condition monitoring.
Best Value: Buy both and save.
The NI PXI-4462 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 of 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 446x devices with less than 0.1 deg of phase mismatch between channels.
Hybrid Slot-Compatible PXI Modules
The PXI-4462 is available in both PXI and PXI Express hybrid slot-compatible form factors. You can use the hybrid slot-compatible PXI-446x modules in PXI slots, CompactPCI slots, and hybrid slots, found in new PXI Express chassis.
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.
