1.25 MS/s, 3.4 Hz AC/DC coupling, 6-input PXI sound and vibration module - PXIe-4480 is designed specifically for high bandwidth audio, acoustic, and vibration measurements. It provides six channels of dynamic signal acquisition, and you can configure the input range using four gain settings. PXIE-4480 also provides software configurable AC/DC coupling, charge measurement, voltage excitation, IEPE excitation and TEDS support, making it an ideal choice for measuring acoustic sensors, pressure sensors and hydrophone. Common applications include audio testing; Noise, Vibration, and Roughness (NVH) Analysis; And underwater acoustic measurements. To measure sudden changes such as high-speed explosions and pressure events, PXIe-4480 can sample at a rate of up to 20 MS/s in the time domain mode of each channel.
