The National Instruments 9234 is a high-performance C Series Sound and Vibration Input Module designed for advanced audio and vibration analysis. It features four simultaneously sampled analog input channels with 24-bit resolution, delivering high-accuracy measurements for applications such as noise, vibration, and harshness (NVH) testing, machine condition monitoring, and audio test. The NI 9234 includes integrated signal conditioning for IEPE (Integrated Electronics Piezo-Electric) and non-IEPE sensors like accelerometers and microphones. With built-in antialiasing filters and a maximum sampling rate of 51.2 kS/s per channel, this module provides reliable data acquisition for dynamic signal analysis within CompactDAQ or CompactRIO systems.
