1. A power supply testing apparatus, comprising:

  • a current source;

    a current sink; and

    a controller, said controller being coupled to said current source and current sink, wherein said power supply testing apparatus is configured for dynamic load testing of a load current between a first amperage value and a second amperage value, said controller controlling said current source and current sink for sourcing current and sinking current with variable slew rate, said slew rate being a change of current over a change of time, said slew rate being determined by adjustment of potentiometers, an amount of current being sourced or sunk being determined by operation of one or more stages wherein each stage comprises a transistor and a current setting resistor.
