Oscilloscopes (A8001)

Learn about Oscilloscopes and their system functions.


This lesson is 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.


This lesson explains and demonstrates 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.


Describe what an oscilloscope is and how it works. Explain the function of its display system, vertical system, horizontal system, trigger system and their controls. Describe different probe types and their applications. Adjust the display controls. Set the trigger, vertical and horizontal controls to display a given waveform on an oscilloscope. Identify sine, square, sawtooth, triangle, pulse, step, and complex waveforms. Measure the voltage, period and frequency of a waveform. Analyze its shape and perform waveform phase measurements.
