The National Instruments USB-9233 is a four-channel dynamic signal acquisition module for making high-accuracy audio frequency measurements from integrated electronic piezoelectric (IEPE) sensors. The NI USB-9233 delivers 102 dB of dynamic range and incorporates IEPE signal conditioning for accelerometers and microphones. The four input channels simultaneously digitize input signals at rates from 2 to 50 kS/s.
Best Value: Buy both and save.
The USB-9233 is also available as a bundle with the NI Sound and Vibration Measurement Suite, which includes NI Sound and Vibration Assistant, at a discount from the list price. See the Resources tab for more information on the list of analysis capabilities in the Sound and Vibration Measurement Suite.
Additional Channel Support
For applications requiring more input channels, consider NI CompactDAQ. You can synchronize up to eight USB-9233 IEPE modules for 32 channels of 24-bit sound and vibration measurements in a single system. In addition, you can use NI CompactDAQ for analog output and other sensor inputs. Alternatively, consider PXI for maximum channel synchronization - up to 5,000 simultaneous 24-bit dynamic signal acquisition channels with less than 0.1 deg phase shift between channels.
Recommended Software
NI sound and vibration analysis software, including the Sound and Vibration Measurement Suite and 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, Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
