Description
The National Instruments PXI-4462 PXI Sound and Vibration Module, with part numbers 779688-01 and 779131-01, is a high-performance Dynamic Signal Acquisition (DSA) Device designed to capture and analyze audio, vibration, and acoustic signals. It features a high-resolution 24-bit analog-to-digital converter and can sample data at a rate of 204.8 kS/s. This module provides four channels for dynamic signal acquisition and offers six gain settings to help configure input ranges for different measurement needs.
The PXI-4462 includes a built-in high-pass filter with a cutoff frequency of 3.4 Hz to eliminate low-frequency noise and improve measurement accuracy. It supports both differential and pseudo-differential terminal configurations for analog inputs, catering to various source conditions. The module can handle an analog overload point of 10.7 Vpk for the 0 dB gain range, ensuring robust performance even in high-signal environments.
It is compatible with a wide array of software packages, including LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, Borland C++, and Microsoft .NET, allowing for flexible application development. Configuration and setup are simplified using the Measurement & Automation Explorer (MAX) tool. Despite its obsolete status announcement by National Instruments, the PXI-4462 remains available for purchase and repairs through Apex Waves.
For ensuring measurement accuracy and reliability, calibration options are available, including NIST accredited calibrations through a third party, as well as basic in-house calibration to manufacturer specifications. These services help maintain the PXI-4462’s precision for critical sound and vibration applications.
