National Instruments USB-4432

The National Instruments USB-4432 is a high-performance Sound and Vibration Device designed for advanced measurement applications. Featuring five differential analog input channels, this device is capable of delivering 24-bit measurements and supports the connection of IEPE sensors. The USB-4432 utilizes a 24-bit delta-sigma ADC which buffers and pre-filters each incoming signal, ensuring the integrity of data acquisition. With a dynamic range of 100 dB and a voltage input range of -40V to +40V, the device provides robust performance under varied conditions and includes ±60V overvoltage protection for enhanced reliability.

The USB-4432 operates in three software-selectable measurement modes: IEPE-on AC coupling, IEPE-off AC coupling, and DC coupling. This versatility, combined with built-in antialiasing filtering, allows the module to effectively differentiate between various signal types. Designed specifically for noise and vibration analysis tasks, this device excels in distortion analysis, noise measurements, and sound quality evaluation. Each channel is equipped with a BNC input connector, making integration into existing setups straightforward. With compact dimensions of 5.6 in. × 7.1 in. × 1.5 in. and a weight of 1.5 lbs., the USB-4432 is highly portable yet powerful, making it suitable for extensive working environments. A comprehensive user manual and maintenance documentation are readily available for download, and further pricing details can be obtained by contacting a sales representative.
