Lesson 1 - SMPS Measurement Basics

In this course, we'll learn how to simplify and automate the characterization of a switch mode power supply (SMPS) using an oscilloscope. 

Testing a SMPS can involve running through a long list of measurements - from AC Input Analysis to Output Ripple. Many engineers rely on an oscilloscope for this characterization and analysis work, but what you may not know is how to best optimize these tests using your oscilloscope. In this course you will learn how to use your oscilloscope to automate these switch mode power supply measurements and save test time. We will walk through the proper test setup for 11 must-know SMPS measurements. 

Who should take Switch Mode Power Supply Testing Basics?

This course is designed for power engineers who want to simplify their SMPS test set-up and save time in the lab.

Regardless of the part of the SMPS you're working on, you'll walk away from this course with the tools to help you better streamline your testing.
