This project is a group of 4 lessons that introduces students to the use of digital storage oscilloscopes (DSO) or Lab Scope in an automotive repair setting.

By the end of the 4-lesson series, students will be able to capture a sensor pattern and reproduce that signal on a lab sheet. Students will use the lab scope and its measuring tool to measure and record analog signals and the main components of the signal such as time, voltage, trigger level, amplitude, frequency, wave length, amplitude, and peak voltage.

By the fourth lesson students will use a dual trace scope to pull 2 sensor patterns and use the scopes measuring cursors to compare the sensor signals. This lesson is not focused on students being able to interpret the signals they will pull from the sensors, but how to use a scope to pull the patterns and how to use the scopes measuring cursors to make the necessary measurements.

All for lessons for this project are:

• Lesson 1 - Lab Scopes - What They Are Measuring
• Lesson 2 - Analog and Digital signals - What’s the difference?
• Lesson 3 – Lab Scopes - How to Connect Them and Get a Pattern
• Lesson 4 - Lab Scopes - Using and Pulling Patterns with a Dual Trace Scope

For this project ,students should have prior knowledge of voltmeters, series and parallel circuits, reading wiring diagrams, using vehicle repair database, and basic information about computers and sensors.
