Description
The Part Number 780421-01 refers to a PC-based DSA model known as USB-4432. This particular model, National Instruments USB-4432 Sound and Vibration Device, is designed to cater to specialized needs in the realm of sound and vibration analysis.
It is equipped with 5 differential analog input channels, although it lacks any analog output channels. The device boasts a 24-bit resolution, ensuring high-quality data capture and processing capabilities. Compatibility is a key feature of this device, supporting both IEPE sensors and TEDS Class 1 sensors, making it a versatile choice for various measurement requirements.
The device’s dynamic range is impressive at 100 dB, and it can handle a wide voltage range from -40V to +40V. To safeguard against potential damage from unexpected voltage spikes, it includes overvoltage protection of ±60V.
For flexibility in measurements, it offers several measurement modes including IEPE-on, IEPE-off (AC coupling), and IEPE-off (DC coupling). The modulation method employed is the delta-sigma method, which is known for its high fidelity in digital signal processing.
The USB-4432 is not just about capturing data; it’s also equipped with features for in-depth analysis, including an antialiasing filter, distortion analysis, noise measurements, and sound quality analysis. Each input channel comes with its own BNC connector, simplifying the connection process for users.
