The National Instruments USB-4432 Sound and Vibration Device, identified by part number 780421-01, is a sophisticated PC-based Dynamic Signal Analyzer (DSA) designed for a broad spectrum of applications. This device stands out in the realm of sound and vibration analysis, thanks to its 5 differential analog input channels that ensure precise and detailed data acquisition.
One of the key features of the USB-4432 is its 24-bit resolution, which is powered by a 24-bit delta-sigma Analog-to-Digital Converter (ADC). This high level of resolution allows for incredibly accurate measurement, capturing the finest nuances in sound and vibration signals. Despite its capability to capture intricate data, the device does not offer analog output channels, focusing solely on data acquisition and analysis.
Compatibility with IEPE sensors is another significant aspect of this device, enabling it to work seamlessly with a wide range of sensors for versatile measurement scenarios. The device supports a variety of measurement modes including IEPE-on, IEPE-off with AC coupling, and IEPE-off with DC coupling, offering flexibility in handling different types of signals.
Boasting a dynamic range of 100 dB and a voltage range from -40V to +40V, the USB-4432 is capable of handling a broad spectrum of signal amplitudes. It also features overvoltage protection up to ±60V, safeguarding the device against unexpected voltage spikes. The built-in antialiasing filter further enhances the quality of measurements by reducing signal aliasing, ensuring that the data captured is both accurate and reliable.
The USB-4432 excels in applications such as noise analysis, vibration analysis, distortion analysis, noise measurements, and sound quality analysis. Its versatility and high performance make it an invaluable tool for professionals and researchers who require precise and comprehensive sound and vibration data analysis.
