PXI module for audio measuresNational Instruments distributes the NI 4472 module specific for high precision audio and vibration measurements on the PXI platform.
With analog-digital 24 bit converters (ADC), this product offers a dynamic range of 120 dB on a bandwidth of 45 kHz.
Owing to simultaneous sampling it can create measurement systems with a high number of channels. The module has eight analog entry channels sampled simultaneously and it can be combined with software LabVIEW, Measurement Studio and LabVIEW Sound and Vibration Toolset to carry out various tests, among which the analysis of octave fractions, spectral analysis and audio level measurements.
Among application examples we quote: the development of systems for the development of noise and vibration testing systems, in the automotive industry; the monitoring of a machine’s conditions and audio tests.
