The NI PXI-4461 is a high precision data acquisition module designed for sound and vibration applications. The module includes the hardware and software needed for accurate measurements using microphones, accelerometers, and other sensors with very large dynamic ranges. Common applications include audio testing, automotive NVH, and machine condition monitoring.

PXI-4461 high precision data acquisition module usually includes sensors, data processing components and storage media. The sensor is responsible for collecting various physical quantities or environmental parameter data of the field and equipment, and the data processing component filters and de-noises the data to improve the accuracy and accuracy of the data, and converts the signal into a standard format that can be recognized by the enterprise internal network for transmission. In addition, the data storage medium ensures that the collected data is securely stored for subsequent query, analysis and processing2.

When selecting a high-precision data acquisition module, users need to consider its performance, accuracy, reliability, cost, and ease of integration into existing systems. At the same time, the maintenance and calibration of the module is also an important part to ensure the long-term accuracy of the data.
