Description
The National Instruments USB-4432 Sound and Vibration Device is a PC-based Dynamic Signal Analyzer (DSA) designed for sound and vibration applications. It features the part number 198755B-02L (780421-01) and falls under the category of PC-based DSA with the model name USB-4432.
This device is equipped with five differential analog input channels but does not include any analog output channels. The measurement resolution provided by this device is 24-bit, ensuring high-precision data acquisition. It is specifically used for measurements from IEPE sensors, utilizing a 24-bit delta-sigma ADC (Analog-to-Digital Converter) for its operations.
One of the notable features of the USB-4432 is its support for TEDS Class 1 sensors, offering compatibility with smart transducers. The device boasts a dynamic range of 100 dB and can handle a voltage range from -40V to +40V. Additionally, it provides overvoltage protection up to ±60V, ensuring the safety of the device under unexpected conditions.
The USB-4432 supports various measurement modes including IEPE-on mode, IEPE-off mode, and IEPE-off mode with DC coupling, catering to diverse measurement requirements. The modulation method employed is delta-sigma modulation, and an antialiasing filter is built into the device to prevent aliasing effects, thereby ensuring the integrity and accuracy of the measurements.
