How the Closed Loop Response (CLR) Testing Helps Streamline the Design Process

Application Note Overview 

Switch-mode power supplies require careful measurement of control loop stability in order to optimize the design’s performance. This application note describes the “Closed Loop Response” (CLR) test and how a Rohde & Schwarz oscilloscope can be used for CLR testing, providing a reliable and economic alternative to other well-known load and line tests. The CLR test allows designers to have increased confidence in their designs, minimizing the risk of a redesign in the product stage.
