ec79bm802a-LNational Instruments introduces its PXI-4498 and PXI-4496 dynamic signal acquisition (DSA) modules that are designed for sound and vibration applications. They 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, beam-forming applications and structural vibration. The PXI-4498 features four analog input voltage ranges, while the PXI-4496 has two analog input voltage ranges. With 16 simultaneous channels in a single PXI module, they can be used 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.
