Abstract
A power supply is provided with independently adjustable voltage and current sources to provide a power supply having a desired voltage-current relationship to a device under test. This allows the control of the power supply output impedance as seen by the device under test and the emulation of a battery or other power supply having particular voltage-current relationships.
