Product Performance
High precision acquisition: 24 bit high resolution ensures high precision and low noise in sound and vibration signal acquisition, enabling signal measurement over a wide amplitude range with a dynamic range of up to 118dB.
High speed sampling: With a sampling rate of up to 204.8kS/s, it can accurately capture rapidly changing sound and vibration signals, and can be used for analyzing transient signals.
Flexible signal conditioning: Equipped with software configurable AC/DC coupling and IEPE conditioning functions, 6 gain settings can adapt to signals of different amplitudes, and users can flexibly configure according to their actual needs.
Signal generation function: Built in signal generation function, supporting various waveform outputs such as sine wave, square wave, triangular wave, etc., which can be used for system testing and calibration.
Spectrum analysis capability: supports real-time spectrum analysis, facilitates frequency domain analysis of sound and vibration signals, and helps to gain a deeper understanding of signal characteristics.
Good software compatibility: Compatible with NI LabVIEW software, combined with NI’s sound and vibration toolkit, it can simplify complex sound and vibration measurement and analysis tasks, and facilitate user data processing and system development.
