Switch mode power supplies (SMPS) are used as a replacement for larger and ultimately inefficient transformers, as well as linear power supplies. SMPS are best evaluated through the use of a digital oscilloscope, appropriate tubes, and auxiliary equipment. This application note provides information on the testing of a Buck-type DC/DC subsystem that uses switch mode power supply technology and the oscilloscopes used to conduct the test.
