Product Performance
High precision measurement: With a 24 bit resolution and a sampling rate of up to 204.8kS/s, coupled with a dynamic range of 118dB, it can achieve high-precision sound and vibration signal acquisition, accurately capturing signal details, and is suitable for measurement scenarios that require extremely high precision.
Flexible signal conditioning: With six gain settings, it can adapt to input signals of different amplitudes. The software has configurable AC/DC coupling function, which can meet various signal measurement needs. It also supports IEPE conditioning and can be directly connected to IEPE sensors.
Multi channel synchronous acquisition: The four channel dynamic signal acquisition function can simultaneously sample and synchronize multiple signals, which helps analyze the sound and vibration characteristics of multiple related measurement points, improve measurement efficiency and accuracy.
Strong anti-interference ability: It can handle both differential and pseudo differential analog input terminal configurations, effectively suppressing common mode interference, improving the stability and reliability of signal measurement, especially in complex electromagnetic environments, and ensuring measurement accuracy.
Good compatibility and scalability: Compatible with PXI bus systems, easy to combine and expand with other PXI modules, easily integrated into existing PXI systems, and supports multiple commonly used programming languages and development environments, making it convenient for users to program and integrate systems according to their needs.
