The NI PXI-4496 is a high-accuracy data acquisition module specifically designed for high-channel-count sound and vibration applications. With 16 simultaneous channels in a single PXI module, it is twice the density of any other simultaneously sampled device from NI. When you use the PXI-4496 in an 18-slot PXI chassis, you can synchronize up to 272 channels. And because the module is programmed with NI-DAQmx featuring DAQmx Channel Expansion functionality, data acquisition code is the same for one channel, 16 channels, or 272 channels. For even larger noise mapping microphone arrays, dynamic structural test, or data streaming applications, you can synchronize more than 13,000 channels in a multichassis PXI system. The PXI-4496 module features a maximum sampling rate of 204.8 kS/s per channel and includes TEDS smart sensor support for error-free setup.

Signal Connectivity
NI 449x devices have two 4X InfiniBand connectors, with each carrying eight input channels, AI0-7 and AI8-15. The 4X InfiniBand is widely used in high-performance computing applications because it provides excellent signal integrity with a shield plate between input signal pairs. NI offers a variety of cabling options including a shielded breakout cable with eight BNC connectors and a 19 in. rack-mountable adapter with 32 BNC connectors.

Best Value: Buy Hardware and Software Together
The PXI-4496 is also available as a bundle with the NI Sound and Vibration Measurement Suite, which includes the NI Sound and Vibration Assistant, at a discount from the list price.

Recommended Software
PXI-4496 modules are programmed with NI-DAQmx and are optimized for use with the NI Sound and Vibration Measurement Suite. The NI Sound and Vibration Measurement Suite provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. For an interactive software experience, NI Sound and Vibration Assistant can quickly acquire, analyze, and log acoustic, noise, and vibration data.
