The National Instruments PCI-4462 high-accuracy data acquisition board is specifically designed for sound and vibration applications. With 24-bit sigma-delta analog-to-digital converters (ADCs), it is ideal for applications including noise emission test and acoustic holography. The NI PCI-4462 features 118 dB dynamic range and six gain settings for precision measurements with microphones, accelerometers, and other transducers that have very high dynamic ranges. Some common applications featuring the PCI-4462 include noise, vibration, and harshness (NVH) test; vibration analysis; and machine condition monitoring.
Best Value - Buy Both and Save
The NI PCI-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 in the Sound and Vibration Measurement Suite.
Multidevice Synchronization for High-Channel-Count Systems
You can synchronize the PCI-4462 with additional PCI-4462 boards to build systems with eight, 12, or more simultaneous inputs. In addition, you can synchronize other dynamic signal acquisition (DSA) boards, such as the NI PCI-4461, with two inputs and two outputs using the PCI-4462 to create systems with 10 simultaneous inputs and two simultaneous outputs (requires one PCI-4461 board and two PCI-4462 boards).
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.
