原廠英文說明
The National Instruments PXI-4461 is a high-accuracy data acquisition module specifically designed for sound and vibration applications. This module includes the hardware and software needed to conduct accurate measurements with microphones, accelerometers, and other transducers that have very high dynamic ranges. Common applications include audio, automotive NVH testing and monitoring of condition of machines. The NI PXI-4461 is also available as a bundle with the NI Sound and Vibration Measurement Suite, which includes NI Sound and Vibration Assistant. For applications requiring thousands of channels, you can synchronize the operation of two or more devices NI 446 x less than 0.1 degree of mismatch between channels.
