Introduction To Oscilloscopes

Introduction To Oscilloscopes


This is the first lesson in the Oscilloscopes Course. This lesson explains the purpose of oscilloscopes, introduces waveforms, and presents analog and digital oscilloscope systems using a flowchart.

Module Objectives

  • Define the purpose and uses of an oscilloscope.
  • Explain the vertical and horizontal axes of a waveform represent.
  • List what can be learned about a signal from a waveform.
  • Recognize the positive and negative peaks on a waveform.


This course contains nine lessons designed for the training of electricians and electronic technicians as well as for the multi-craft training needs of process and manufacturing facilities. These lessons are designed for participants familiar with AC and DC theory, electrical safety, and electrical print reading. A basic understanding of electronic devices and circuits is recommended. The lessons in this course explain and demonstrate the use of both analog and digital oscilloscopes. Participants will learn the controls on each type of oscilloscope, how to use a probe with an oscilloscope, how to set up an oscilloscope, and how to determine various measurements taken with an oscilloscope.
