Verified 2026-10-27 Confidence: Medium

Modern sets are modular: a control unit drives one or more current source modules, more modules being added when higher test currents are needed, and the output voltage can be raised at the expense of output current so that the test current is driven through a high-burden circuit; a long control cable lets the current source sit close to the test object so that the heavy current leads stay short.
