Abstract
An example test system includes an output stage to source at least one of voltage or current to a channel of a test instrument; a tracking circuit to detect a channel voltage following the output stage and to control a supply voltage to the output stage based on the channel voltage; and a controller to determine a power dissipation of the output stage based on the supply voltage and the channel voltage, and to control the output stage based on the power dissipation in the output stage.
