What Is the PXI Sound and Vibration Module?

The PXI Sound and Vibration Module is designed specifically for applications like audio test and measurement, noise and vibration diagnostics, machine condition monitoring, automotive test, noise, vibration, harshness (NVH) analysis, and laboratory research.

Perform Signal-Chain Distortion Analysis

The PXIe-4468 sound and vibration module enables benchtop-quality signal-chain distortion analysis in a single-slot PXI Express form factor. Additional new features include Pure Tone sine wave generation mode for more test coverage as well as support for independent operation and synchronization of each channel for improved utilization in test systems.

Generate and Acquire High Dynamic Range Signals

NI’s PXI Sound and Vibration Module is a dynamic signal acquisition (DSA) device that can accurately measure the frequency content of signals with a very high dynamic range. Modules provide software-configurable AC/DC coupling, antialiasing filters, and IEPE conditioning to ensure precision measurements with microphones, accelerometers, and other transducers with large dynamic ranges.

Add Accelerometer Measurements to Your System

PXI Sound and Vibration Input Modules and the accompanying NI software make it fast to connect microphones and accelerometers to the module for vibration test and measurement. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
