 Data Sheet
Please select the country where you will use the product(s) so that we can provide you with accurate pricing, availability, and purchasing information
The National Instruments PCI-4461 high-accuracy data acquisition module is specifically designed for sound and vibration applications. With 24-bit sigma-delta analog-to-digital converters (ADCs) and 24-bit analog output, it is ideal for stimulus-response applications including audio and structural tests. The NI PCI-4461 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 with the PCI-4461 include audio amplifier and production equipment test, shaker table control, vibration analysis, and machine condition monitoring.
Best Value - Buy Both and Save
The PCI-4461 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 High-Channel-Count Systems
You can synchronize the PCI-4461 with additional PCI-4461 boards to build systems with six simultaneous inputs and six simultaneous outputs (requires three PCI-4461 boards). In addition, you can synchronize other dynamic signal acquisition (DSA) boards, such as the four-input NI PCI-4462, with the PCI-4461 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.
