Description
The PXIe-4468 is a state-of-the-art PXI Sound and Vibration Module designed for a wide array of applications, including audio testing, automotive noise, vibration, and harshness (NVH), and machine condition monitoring. This module stands out due to its dual functionality, offering two-channel dynamic signal generation and acquisition, making it a versatile tool for engineers and technicians in various fields.
The module is available with two different connector types, Mini-XLR and BNC, to accommodate different connection needs. Specifically, the part numbers are 788512-01 for the Mini-XLR connector version and 788511-01 for the BNC connector version. This flexibility ensures that users can choose the connector type that best fits their existing equipment and setup requirements.
One of the PXIe-4468’s notable features is its six gain settings, which allow users to configure the input range according to their specific needs. This feature, along with the module’s ability to support both AC and DC input coupling, enhances its adaptability to various signal types and amplitudes. Furthermore, the module includes IEPE conditioning and a built-in tone generator, expanding its utility for sound and vibration analysis.
The output stage configuration of the PXIe-4468 is particularly sophisticated, offering both differential and pseudodifferential modes. These modes are software-configurable, providing users with the flexibility to select the configuration that best matches their measurement requirements. Additionally, any gain difference encountered in pseudodifferential mode is automatically corrected by the software or can be manually adjusted through an external connection, ensuring accurate measurements.
For environments where common-mode noise could be a concern, the PXi-4468 module has been designed with features to combat this issue. It is recommended to connect the chassis ground of the PXIe-4468 to the ground of the input device, which significantly enhances the module’s common-mode noise rejection capabilities, ensuring cleaner, more reliable data.
