The PXI‑4464 allows simultaneous sampling of all channels. In addition, the PXI‑4464 includes a built-in anti-aliasing filter that automatically adjusts to the sampling rate, six software-selectable input gain ranges, and TEDS smart sensor support to ensure correct installation configuration. The IEPE excitation circuit is responsible for providing current to the high-power sensor while maintaining data integrity over long distance sensor cables.The PXIe-4492 is a high-performance PXI sound and vibration module designed specifically for sound and vibration applications. With a 24-bit analog input and IEPE constant current signal conditioning, the module is suitable for precision measurements in combination with microphones, accelerometers and other sensors with a large dynamic range. The PXIe-4492 supports synchronous sampling across all channels, with high sampling rates and fast data transmission capabilities, enabling fast and accurate data acquisition.
In addition, the PXIe-4492 is equipped with a high-precision analog converter (ADC) to achieve better analog signal measurement, providing high-resolution sampling and better signal reconstruction functions. The module supports configurable input range and gain adjustment to suit the measurement needs of different signal types and amplitude ranges.
In terms of applications, the PXIe-4492 is widely used in noise, vibration and acoustic roughness (NVH) analysis, large and large microphone arrays, and dynamic structure testing. At the same time, due to its high performance and flexibility, the module is also suitable for various test, measurement and control applications, including automated test equipment (ATE), instrument control, data logging, etc.
