The NI 9233 is obsolete. For new designs we recommend the NI 9234. The NI 9233 is a four-channel dynamic signal acquisition module for making high-accuracy audio frequency measurements from IEPE sensors with NI CompactDAQ or CompactRIO systems. The NI 9233 delivers 102 dB of dynamic range and incorporates integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones. The four input channels simultaneously digitize signals at rates from 2 to 50 kHz per channel with built-in antialiasing filters that automatically adjust to your sampling rate.
Recommended Software
NI sound and vibration analysis software, including the NI Sound and Vibration Measurement Suite and the NI Sound and Vibration Toolkit, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. NI analysis software features NI Sound and Vibration Assistant interactive software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data. With a configuration-based, flexible measurement library and open-analysis capability, the Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
