Digital Sourcemeter
See Digital Sourcemeter ProductsSource 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.
