National Instruments PXIE-4499 Sound and Vibration Module

Title: National Instruments PXIe-4499 Sound and Vibration Module Overview

Introduction: The National Instruments PXIe-4499 (Part Number: 781370-01) Sound and Vibration Module is a cutting-edge solution designed to address various testing needs, offering advanced features and capabilities.

1. Digital Signal Processing:
   • The module is equipped with a digitizer or ADC capable of testing signals with frequency components beyond the Nyquist limit.
   • Nyquist data transfer capacity is vulnerable to aliasing, making it essential to avoid its occurrence during ADC output observation.
   • Lowpass filtering, applied either before or during digitization, helps eliminate components over the Nyquist frequency, ensuring alias-free data collection.
   • DSA devices utilize a combination of digital and analog lowpass filters for comprehensive protection.
2. Delta-Sigma ADC Technology:
   • The PXIe-4499 features delta-sigma ADCs with oversampled architecture and sharp digital filters.
   • Digital filters automatically adjust to track the Nyquist frequency, effectively eliminating alias artifacts.
   • The AI.RemoveFilterDelay property is supported, enabling automatic alignment of acquired data with the digital trigger.
3. Triggering Mechanism:
   • The trigger circuit generates an internal digital trigger, independent of the input signal and defined trigger levels.
   • Users can configure the device to start acquiring samples after the input signal crosses a specified threshold.
