Kit Content

• NI 9231

• NI 9231 Getting Started Guide

Target Applications

• Audio Testing

• Noise, Vibrations, and Harshness (NVH)

Provides dynamic signal acquisition in sound and vibration applications for CompactDAQ and CompactRIO systems.

The C Series Sound and Vibration Input Module incorporates software-selectable AC/DC coupling, IEPE open/short detection, and IEPE signal conditioning. The input channels simultaneously measure signals. Each channel also has built-in anti-aliasing filters that automatically adjust to your sample rate. The modules are compatible with smart TEDS sensors.The C Series Sound and Vibration Input Module includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
