About D.E.V.I.C.E.
Search:

A switch used in electric circuit that redirects the path of electric current depending on the current inputs to the switch.

When testing a power supply in this mode, there is current floating through the electronic load linearly proportional to the input voltage in accordance with the preset resistance. At the same time the use of a combined mode (constant resistance mode changing to direct voltage mode) additionally provides protection to the power supply under test against current surge during the changing process.

Ripple and noise
There are two distinct components to the output noise. These are commonly referred to as ‘ripple’ and ‘noise’.

Rise Time

 The time period for which the pulse level changes starting from the low reference value (usually 10%) up to the top reference value (usually 90%).
