There are a number of reasons why measuring the output ripple in switching regulators is such an important and delicate task. It is possible to receive erroneous readings while trying to measure this ...

Even if you don’t have a Rohde Schwarz oscilloscope, you can still enjoy their recent video about using an oscilloscope to measure power supply efficiency. Of course, you don’t have to have a scope to ...

The prosaic DC power supply is receiving scrutiny as supply voltages continue to get smaller. Supply tolerances are getting tighter as users try to decrease power, increase yield and minimize supply ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

This video shows how to use the FFT function of RIGOL oscilloscopes. The FFT function allows the user to measure the frequency and time domain of the signal waveform, at the same time. In this ...
