|NI Releases 10 New Express VIs and Highest-Performance PCI Board for
Sound and Vibration Applications|
National Instruments today announced
the release of a 24-bit data acquisition and generation module, the NI PCI-4461, marking the highest-performance
dynamic signal acquisition (DSA) board on the PCI bus with a 118 dB dynamic range. The release also includes the
National Instruments LabVIEW Sound and Vibration Toolkit Version 4, with 10 new Express VIs for simplified
application development. These new products add to the comprehensive NI hardware and software tools for sound and
vibration applications, including PXI, PCI and USB measurement devices and powerful, easy-to-use analysis
In addition to 24-bit output channels on PCI, the PCI-4461
DSA board offers two 24-bit input channels, making it ideal for stimulus response applications such as audio and
structural tests. Engineers can synchronize multiple PCI-4461 boards to attain four-input and four-output systems or
six-input and two-output systems for applications such as simultaneous 5.1 speaker surround sound test or acoustic
holography. The PCI-4461 board also features IEEE 1451.4 transducer electronic data sheet (TEDS) capability, which
simplifies the configuration of a microphone or an accelerometer measurement.
The NI LabVIEW
Sound and Vibration Toolkit 4 now is easier to use with 10 new Express VIs for interactively developing applications
and generating code for fractional octave analysis, frequency response, vibration and sound level and other common
analyses. Engineers can customize applications such as integrated vibration level measurements, weighted sound level
measurements, swept sine analysis, power spectrum analysis, limit testing and transient analysis.
Engineers can further extend their sound and vibration analysis with the upgraded LabVIEW Order Analysis
Toolkit 2.1 that features an easier-to-use application programming interface and simpler graphing options. With
improved resampling and Gabor techniques for online and off-line analysis capability, the toolkit is ideal for order
tracking, order extraction and tachometer signal processing. Simplified visualization capabilities include orbit,
polar, bode, cascade, waterfall and shaft centerline plots.
