Power Supply parameters - Loop Response

#187 In this video I look at a more complex power supply related measurement that is supposed to tell you how stable the supply is and how fast it can react, among other things. The test in question refers to characterizing the feedback loop - how will the power supply react based on the frequency of the perturbation applied?
