Description
The PXIe-4468 is a high-performance PXI Dynamic Signal Acquisition (DSA) device designed for a wide range of applications, including audio testing, automotive noise, vibration, and harshness (NVH), and machine condition monitoring. This device features two-channel dynamic signal generation and acquisition, making it versatile for various signal analysis tasks.
The PXIe-4468 model offers six selectable gain settings, allowing users to adjust the input sensitivity according to the requirements of their specific application. It supports both AC and DC coupling, catering to a wide array of signal types. Furthermore, it is equipped with Integrated Electronic Piezoelectric (IEPE) signal conditioning, facilitating direct connections with sensors that require constant current excitation.
This device comes in two part numbers, 788512-01 and 788511-01, which differ in their front connector types. The 788512-01 version uses Mini-XLR connectors, while the 788511-01 version employs BNC connectors, providing flexibility in connecting to various types of equipment.
Additionally, the PXIe-4468 includes a built-in tone generator, which is useful for test signal generation in audio testing scenarios. Its output stage can be configured either in a differential mode or a pseudodifferential mode, depending on the application needs. In pseudodifferential mode, a gain difference of -22.0 mdB is automatically corrected by software or can be manually corrected via an external connection.
In summary, the PXIe-4468 is a robust and flexible solution recommended for professionals involved in audio testing, automotive NVH analysis, and machine condition monitoring. Its comprehensive feature set, including selectable gain settings, AC/DC coupling, IEPE conditioning, and a built-in tone generator, make it a powerful tool for dynamic signal analysis.
