The tutorial video “How to measure Buck converter loop gain and phase” will explain the basics of control loop measurements and will show you how to use the PicoScope with a Frequency Response Analyzer (FRA) utility which you can download at https://bitbucket.org/hexamer/fra4picoscope/downloads/
We’ll also explain how to make the signal injection transformer that you need for this measurement. The video gives many practical tips and examples on converter stability measurement that can also be applied to many other converter types.
