Designing a Portable Multi-Channel DAQ for Non-Destructive Testing

Do you have to conduct non-destructive testing of materials? This is a common requirement when testing for material defects, weld integrity and stress. In this application note the engineers at NuHorizons outline a system that includes:

  • Analog to Digital Converter (ADC) to measure the reflected signal
  • FPGA to collected converted data
  • Regulator for on-board power distribution
  • Microcontroller for system level functions
  • Display to show the images

This application brief summarizes the device selection process and key design considerations for a portable multi-channel data acquisition unit.
