As a 4-channel C series dynamic signal acquisition module, NI 9234 can perform high-precision audio measurement for integrated circuit piezoelectric (IEPE) and non-integrated circuit piezoelectric (IEPE) sensors equipped with NI CompactDAQ or NI CompactRIO systems. The NI 9234 has a dynamic range of 102 dB and can perform software-selectable integrated circuit piezoelectric (IEPE) signal conditioning for acceleration sensors and microphones. The 4 input channels use built-in anti-aliasing filters that automatically adjust the sampling rate while digitizing the signal at a rate of up to 51.2 kHz per channel.
Recommended software
NI Sound and Vibration Analysis Software(Contains: NI Sound and Vibration Measurement Suite and NI Sound and Vibration Suite)Provides signal processing functions for sound measurement, fractional octave analysis, frequency analysis, transient analysis and order tracking. NI analysis software has the NI Sound and Vibration Assistant (Sound and Vibration Assistant) interactive software, which can quickly collect, analyze, and record acoustic, noise, and vibration data. With a flexible and configuration-based measurement library and open analysis functions, the Sound and Vibration Assistant can perform unique software-based measurements to quickly collect data and create custom applications.
