This Picotest video gives a quick overview of the many power-related measurements that can be made using a Tektronix oscilloscope and Picotest accessories. Advanced power supply tests, such as control loop stability and rejection ratio require special instrumentation in addition to oscilloscopes, probes, and software to handle signal injection and provide isolation.  Similarly, characterizing power rail impedance and analyzing noise can also require supplementary accessories. Picotest provides accessories and expertise that can work with Tektronix oscilloscopes and probes to make these measurements and more.
