PCI-4461, 204.8 kS/s, 118 dB, 3.4 Hz AC/DC Coupled, 2-Input/2-Output Sound and Vibration Device

779307-01 - NI (National Instruments)

The PCI‑4461 is a high-accuracy data acquisition module specifically designed for sound and vibration applications. It provides simultaneous two-channel dynamic signal generation and simultaneous two-channel dynamic signal acquisition with six gain settings to configure the input range. The PCI‑4461 also includes software-configurable AC/DC coupling and integrated electronic piezoelectric (IEPE) conditioning to ensure precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. Common applications include audio test; automotive test; noise, vibration, and harshness (NVH) analysis; and machine condition monitoring.
