Engineers and product designers now can easily build complex, synchronised systems for high-channel-count applications with the new National Instruments high-accuracy DAQ modules specifically designed for sound and vibration applications.

The PXI-4498 and PXI-4496 dynamic signal acquisition (DSA) modules offer 16 simultaneous 24bit analogue 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 analogue input voltage ranges, while the NI PXI-4496 has two analogue input voltage ranges. With 16 simultaneous channels in a single PXI module, the devices are claimed to be the most dense DSA modules from NI. Engineers can use the modules with an 18-slot PXI chassis to hold 272 synchronised channels in a single chassis and more than 13,000 synchronised channels in a distributed PXI system. The modules feature a maximum sampling rate of 204.8KSPS per channel and include TEDS smart sensor support for error-free setup.

The DSA modules work with all existing PXI modules. The new devices can also integrate with various software including the NI's LabVIEW graphical development environment and LabVIEW SignalExpress. The modules come with NI-DAQmx driver software for easy configuration.

The PXI-4498 and PXI-4496 DSA modules are priced from Rs.3.26 lakh ($7,999).
