The National Instruments PCI-4472 / PXI-4472 Series 24-Bit 8- and 4-Channel Dynamic Signal Acquisition Modules features three modules: the 4472, the 4472B, and the 4474. The National Instruments PCI-4472 and PXI-4472 are 8-channel dynamic signal acquisition devices for making high-accuracy audio-frequency measurements. The vibration-optimized NI PXI-4472B offers a lower AC cutoff frequency of 0.5 Hz. Input channels incorporate Integrated Electronic Piezoelectric (IEPE) signal conditioning for accelerometers and microphones. The input channels of an NI 447x simultaneously digitize input signals over a bandwidth from DC to 45 kHz. You can synchronize multiple NI 447x devices for high-channel-count applications, or with other modules using the PXI star trigger bus or the RTSI bus on PCI.

NI 4472 devices have eight analog inputs with 24-bit resolution ADCs that are simultaneously sampled at a software-programmable rate. The high resolution provides the necessary accuracy to make NI 4472 devices well-suited for audio and vibration analysis applications.
