The NI PXI-4498 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 has twice the density of any other simultaneously sampled device from NI. When you use the NI PXI-4498 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-4498 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.
