16 simultaneously sampled analog inputs at up to 204.8 kS/s

　　Software-configurable 4 mA IEPE and TEDS for microphones and accelerometers

　　Synchronization of up to 272 channels at full bandwidth in a single PXI Express chassis

　　概览：

　　The NI PXIe-4497 is a high-accuracy data acquisition (DAQ) module specifically designed for high-channel-count sound and vibration applications. With 16 simultaneous channels in a single PXI Express module, it has twice the density of any other simultaneously sampled device from NI. When you use the NI PXIe-4497 in an 18-slot PXI Express chassis, you can synchronize up to 272 channels and acquire data at 204.8 kS/s per channel. And because the module is programmed with NI-DAQmx featuring DAQmx Channel Expansion functionality, the data acquisition code is the same for 1, 16, 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 Express system.

　　Signal Connectivity

　　NI 449x devices have two 4X InfiniBand connectors, AI0-7 and AI8-15, each carrying eight input channels. 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

　　NI PXIe-4497 modules are programmed with NI-DAQmx and are optimized for use with the Sound and Vibration Measurement Suite. The suite provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. For an interactive software experience, the Sound and Vibration Assistant can quickly acquire, analyze, and log acoustic, noise, and vibration data.
