Description
The National Instruments PXI-4461 is a PXI Sound and Vibration Module designed for a variety of applications including audio test, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring. The module is recognized by its part number 188003B-01 (779687-01) and falls under the category of PXI DSA.
This module features two-channel dynamic signal generation and two-channel acquisition, allowing for versatile use in various testing and measurement scenarios. It offers an input range design with six gain settings to accommodate a wide range of signal amplitudes. Moreover, the PXI-4461 provides programmable AC/DC coupling and IEPE conditioning, enhancing its compatibility with different sensor types and applications.
The terminal arrangements for analog input (AI) are differential and pseudo-differential, offering flexibility in connection and reducing signal noise and interference. To ensure safety and reduce electrical noise, the resistance between the BNC shell and the chassis frame is maintained at 50 Ω.
Equipped with digital filters, the PXI-4461 module effectively prevents aliasing, ensuring accurate data acquisition and signal generation. Each channel’s configuration is configurable on a per-channel basis, allowing for tailored setups that meet specific requirements. Furthermore, the module’s acquisition clock can be synchronized with other devices, enhancing the precision and accuracy of multi-device measurements.
The PXI-4461 supports both digital and analog triggering, providing versatility in initiating measurements or signal generation based on predefined conditions. Lastly, with 24-bit resolution analog-to-digital converters, this module ensures high-precision data acquisition, making it a suitable choice for demanding applications that require detailed analysis and accurate results.
