Product Introduction
The NI PXIe-4497 is a high-performance dynamic signal acquisition (DSA) module designed for precision sound, vibration, structural dynamics, and condition monitoring applications. As part of the National Instruments Dynamic Signal Acquisition family, the PXIe-4497 delivers simultaneous 24-bit analog measurements with integrated IEPE signal conditioning, making it an ideal solution for microphones, accelerometers, force sensors, and other dynamic transducers.
Featuring 16 simultaneously sampled analog input channels, built-in anti-aliasing filters, and high dynamic range, the PXIe-4497 enables engineers to acquire highly accurate synchronized measurements for research, product validation, and industrial testing.
Product Overview
The PXIe-4497 is optimized for dynamic measurements where phase accuracy, low noise, and simultaneous sampling are critical. Every analog input channel has its own 24-bit ADC and anti-aliasing filter, ensuring precise phase alignment across all channels.
Integrated IEPE excitation eliminates the need for external signal conditioning when connecting ICP® microphones, accelerometers, and other IEPE sensors. Combined with the PXI Express platform and NI software ecosystem, the PXIe-4497 provides a scalable solution for multi-channel structural, acoustic, and vibration analysis.
