OVERVIEW

Goal Evaluate, select, and use an oscilloscope.
Task-based Objectives
  • Understand sensitivity, accuracy, precision, and noise that effect your measurement sample quality
  • Ensure you are using an oscilloscope with the right bandwidth and options to capture your signal accurately
  • Select the correct sample rate to prevent aliasing or take advantage of the aliasing principle
  • Make measurement decisions regarding measurement type, filtering, and sampling type
  • Choose the most effective sampling method between real-time, interleaved, and interpolated
  • Select the proper record length for an acquisition and calculate the memory needed in the instrument
  • Select the right probe for your application
  • Properly use and configure oscilloscope trigger types to capture the right data
  • Select the right settings for coupling and impedance
