The National Instruments PXI-4496 is a high-performance PXI Sound and Vibration Module designed specifically for sound and vibration applications. Available in two configurations, part number 779748-01 features the standard module, while part number 779748-02 includes the Sound and Vibration Measurement Suite software. The PXI-4496 is equipped with sixteen 24-bit input channels, offering IEPE constant current signal conditioning, making it ideal for precise measurements with a variety of transducers, including accelerometers and microphones. This module boasts an impressive dynamic range of up to 114 dB and supports synchronous testing across all 16 channels at sampling rates reaching 204.8 kS/s.

Utilizing delta-sigma modulation for analog-to-digital conversion, the PXI-4496 processes input signals through oversampling and digital filtering, ensuring exceptional phase linearity while minimizing noise and distortion. The implementation of antialiasing filters in both analog and digital domains protects against unwanted high-frequency signals, allowing for high-fidelity data acquisition without the need for additional external filtering hardware. With a robust design and a warranty of 2-3 years, the PXI-4496 is a reliable choice for engineers and researchers requiring accurate sound and vibration measurement solutions.
