Description
The PXIe-4468 is a high-precision PXI Sound and Vibration Module manufactured by National Instruments. This dynamic signal generation and acquisition module is designed for a wide range of applications, including audio testing, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring. It offers 2-Channel Dynamic Signal Generation and Acquisition, providing users with versatile capabilities in sound and vibration measurements.
The module comes in two part numbers, 788512-01 (MXLR) and 788511-01 (BNC), catering to different types of front connector types, namely Mini-XLR (MXLR) and BNC. This flexibility allows for easy integration into various test setups, enhancing connectivity and compatibility.
With 6 Gain Settings, the PXIe-4468 offers users the ability to fine-tune their signal acquisition, ensuring precise measurements across a range of applications. The module supports both AC and DC coupling, providing further adaptability for different signal types. Additionally, the inclusion of IEPE (Integrated Electronics Piezo-Electric) conditioning enables direct connection to IEPE sensors, streamlining the setup for vibration and acoustic measurements.
One of the standout features of the PXIe-4468 is its built-in tone generator, which is ideal for system calibration and test signal generation. The module’s output stage can be configured in differential mode or reconfigured to pseudodifferential mode, catering to the needs of various applications. In pseudodifferential mode, any gain difference is automatically corrected by software, with a correction factor of -22.0 mdB, ensuring accurate measurements and minimizing setup complexity.
In summary, the PXIe-4468 module from National Instruments is a versatile and high-performance solution for sound and vibration analysis. Its wide range of features, including multiple gain settings, versatile connector types, and built-in tone generator, make it a powerful tool for professionals in audio testing, automotive NVH analysis, and machine condition monitoring.
