Abstract
A source measure unit has a voltage output stage to provide a voltage across first and second output terminals to connect to a load, and a current output stage to provide a voltage to a first sense resistor, the source measure unit to switchably employ both the voltage output stage and the current output stage for a first range of output current, to regulate a common point, and either output voltage or output current, or employ only one of either the voltage output stage or the current output stage to provide voltage to both the first and second output terminals and a second sense resistor for a second range of output current, and to regulate either output voltage or output current.
