- 24-bit resolution ADCs with 102 dB dynamic range
- Simultaneously sampled analog inputs at up to 51.2 kS/s
- ±5 V input range
- AC coupling and IEPE conditioning always enabled
- Variable antialiasing filters
- Ability to synchronize up to 32 channels in NI CompactDAQ or CompactRIO systems
The National Instruments USB-9233 and NI 9233 modules for NI CompactDAQ and CompactRIO are dynamic signal acquisition devices for making high-accuracy sound and vibration measurements. They combine 24-bit sigma-delta ADCs and antialiasing filters with IEPE sensor conditioning for microphones and accelerometers.
Recommended Software
NI sound and vibration analysis software, which includes 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 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.
