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.
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.
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.
LabVIEW and PXI Sound and Vibration Modules provide the basis for a modular hardware architecture for analog audio testing.
Hyundai Motor Group challenges used NI hardware and software to improve quality by visualizing and identifying annoying transient buzz, squeak, and rattle (BSR) noise sources.
Combining LabVIEW and PXI hardware, including sound and vibration hardware, Dolphin Integration created an automated test bench for high-resolution audio test.
