Fnirsi is one of those brands that seem to pop up more and more often, usually for portable oscilloscopes and kin. Their IPS3608 bench power supply is a bit of a departure from that, offering a ...

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 ...

Although variable dc power supplies might appear to be relatively simple instruments, engineers rely on them to deliver stable, precise, and clean voltages and currents, regardless of the load. To ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Power supplies are among the most popular pieces of electronic test equipment. This isn’t surprising, as controlled electrical energy is used in a tremendous number of ways. The term “bench” or ...

Input ratings: Typical power-supply modules are designed and rated to operate with their inputs connected to lines delivering 105 to 125 Vac. Most 115-Vac power systems maintain line voltage within ...
