Description
The National Instruments PXI-4461 is a PXI Sound and Vibration Module designed for a wide range of applications. This module, with the part number 188003G-01L (779687-01), falls under the category of PXI DSA, showcasing its versatility in dynamic signal analysis. It is equipped with two-channel dynamic signal generation and acquisition, making it a powerful tool for engineers and researchers.
The PXI-4461 module offers a flexible input range design, allowing users to select one of six gain settings to match the requirements of their specific application. Furthermore, it features programmable AC/DC coupling and IEPE conditioning, enhancing its capability to accurately capture and analyze signals. This makes the module particularly well-suited for applications such as audio testing, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring.
When it comes to terminal arrangements for AI (Analog Input), the PXI-4461 supports both differential and pseudo-differential configurations. This flexibility ensures compatibility with a wide range of sensor types and signal sources. Additionally, the resistance between the BNC shell and chassis is specified at 50 Ω, ensuring a reliable and consistent connection.
The inclusion of digital filters in the module is a critical feature, designed to prevent aliasing and ensure the integrity of the signal being analyzed. Moreover, the PXI-4461 supports signal synchronization with other devices in the system, enabling complex, multi-channel analysis with precise timing. Triggering options are robust as well, including both digital and analog methods, which allows users to capture specific events or conditions accurately.
With a 24-bit resolution for analog input channels, the PXI-4461 delivers high-fidelity signal acquisition. Sampling rates are software-programmable, including options such as 44.1 kS/s and 48 kS/s, providing users with the flexibility to tailor the sampling to meet the needs of their specific application. This level of detail and control makes the PXI-4461 an essential tool for any sound and vibration analysis task.
