102.4 kS/s, 3.4 Hz AC/DC-Coupled, 8-Input PXI Sound and Vibration Module—The PXI‑4472 is a dynamic signal acquisition module designed for sound and vibration measurements. Input channels incorporate integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones, and built-in antialiasing filters that automatically adjust to your sample rate. The eight PXI‑4472 input channels simultaneously digitize input signals. You can synchronize multiple PXI‑4472 modules with each other for high‑channel‑count applications, or with other devices using the RTSI bus.
