Digital Sourcemeter

See Digital Sourcemeter Products

Source meters are typically used in automatic test equipment and they usually come with an interface such as GPIB or USB to enable connection to a computer. However they can also be used in lab bench for characterization purpose. Typically Source meters have four terminals. Two for source and measurement and two more for kelvin connection.
