Engineers and product designers now can easily build complex, synchronized systems for high-channel-count applications with the new National Instruments (Nasdaq:NATI) high-accuracy data acquisition modules specifically designed for sound and vibration applications.
The National Instruments PXI-4498 and PXI-4496 dynamic signal acquisition (DSA) modules offer 16 simultaneous 24-bit analog inputs per module and IEPE constant current signal conditioning for precision measurements with microphones and accelerometers in high-channel-count systems, such as noise mapping, beamforming applications and structural vibration. The NI PXI-4498 features four analog input voltage ranges, while the NI PXI-4496 has two analog input voltage ranges. With 16 simultaneous channels in a single PXI module, these are the most dense DSA modules from NI. Engineers can use the modules with an 18-slot PXI chassis to hold 272 synchronized channels in a single chassis and more than 13,000 synchronized channels in a distributed PXI system. The modules feature a maximum sampling rate of 204.8 kS/s per channel and include TEDS smart sensor support for error free setup.
The new DSA modules work with all existing PXI modules and integrate with a variety of software including the National Instruments LabVIEW graphical development environment and LabVIEW SignalExpress, as well as the NI Sound and Vibration Measurement Suite and Sound and Vibration Assistant. The modules come with NI DAQmx driver software for easy configuration.
PCI eXtensions for Instrumentation (PXI) is an open specification governed by the PXI Systems Alliance (www.pxisa.org) that defines a rugged, CompactPCI-based platform optimized for test, measurement and control. Founded in 1997, the PXI specification is supported by more than 70 member companies and more than 1,200 products are available. PXI products are compatible with the CompactPCI and CompactPCI Express industrial computer standards and offer additional features such as environmental specifications, standardized software and built-in timing and synchronization.
