National Instruments, Austin, TX, offers the USB-4431 dynamic signal acquisition (DSA) module, 3 high-accuracy accelerometers, a triaxial accelerometer, and an impact hammer for making high-accuracy vibration measurements for NVH and machine condition monitoring applications. The 5-channel DSA makes high-accuracy measurements from IEPE sensors and features four 24-bit simultaneously scanned analog inputs, one 24-bit analog output, 100 dB of dynamic range, and software-selectable IEPE signal conditioning for accelerometers and microphones. The accelerometers have low-impedance outputs for accurate signal transmission over long cables. The modal analysis impact hammer lets you measure stimulus signals.
