Abstract
An input by-pass circuit for a current probe has first and second switches coupled between current probe inputs and current sensing circuit inputs. A switch control is coupled to the switching circuit for selectively coupling and decoupling the current probe inputs to the current sensing circuit such that the current signal continuously flows in the device under test.
