Description
The National Instruments PXI-4461 is a PXI Sound and Vibration Module designed for a wide range of applications, including audio testing, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring. This module features a part number 779687-01 and falls under the category of PXI DSA (Dynamic Signal Acquisition).
It offers two-channel dynamic signal generation and two-channel acquisition, making it versatile for both input and output audio signal processing. The PXI-4461 is equipped with six gain settings in its input range design, allowing users to adjust the signal strength as needed. For signal coupling and conditioning, it provides programmable AC/DC coupling and IEPE conditioning, enhancing the module’s flexibility in various testing environments.
The module supports both differential and pseudo-differential terminal configurations for analog inputs, ensuring compatibility with a wide range of sensors and signal types. Its input channels are configurable per channel, featuring digital filters to prevent aliasing and ensure the integrity of the signal processing.
With 24-bit ADCs that are simultaneously sampled, the PXI-4461 guarantees high-resolution data acquisition. Users can benefit from its software-programmable sampling rates, such as 44.1 kS/s and 48.0 kS/s, allowing for precise control over data collection. Furthermore, the module’s acquisition clock can be synchronized with other devices, facilitating coordinated measurements in complex setups.
The PXI-4461 supports both digital and analog triggering, offering flexibility in initiating data acquisition. Calibration is available and is recommended annually or every two years to maintain accuracy and performance. This module represents a comprehensive solution for professionals seeking high-quality sound and vibration analysis capabilities.
