Description
The National Instruments PXIe-4468 PXI Sound and Vibration Module is an advanced tool designed for a variety of applications, including audio testing, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring. This module is available in two part numbers: 788512-01, which features a Mini-XLR front connector, and 788511-01, equipped with a BNC front connector.
It boasts a two-channel dynamic signal generation and acquisition system, enabling precise measurements and analysis. The module offers six configurable input range settings, allowing users to adapt to various signal levels for optimal data acquisition. Additionally, it supports both AC and DC coupling, providing flexibility in connecting to different signal sources.
One of the key features of the PXIe-4468 is its IEPE (Integrated Electronics Piezo-Electric) conditioning, making it suitable for direct connection to IEPE sensors. This feature simplifies setup and enhances signal quality. Moreover, the module includes a built-in tone generator, which is invaluable for test signal generation, system calibration, and troubleshooting.
The output stage of the PXIe-4468 is a differential amplifier, which can be configured to a pseudodifferential mode. This flexibility is critical in applications requiring the reduction of noise and interference. The gain difference in pseudodifferential mode is -22.0 mdB, which is automatically corrected by software when configured internally, ensuring accurate measurements.
Furthermore, the module’s common-mode noise rejection is significantly improved when the chassis ground is connected to the input device ground. This feature is essential for applications where signal integrity and noise reduction are paramount.
Overall, the National Instruments PXIe-4468 PXI Sound and Vibration Module is a versatile and powerful tool for professionals in various industries requiring precise sound and vibration analysis.
