Abstract
An example test system includes power amplifier circuitry to force voltage or current to a test channel and one or more processing devices configured to control the power amplifier circuitry to comply with a compliance curve. The compliance curve relates output of the voltage to output of the current. According to the compliance curve, maximum current output increases as an absolute value of the voltage output increases.
