Abstract
The present disclosure relates to calibration devices for alternating current (AC) and direct current (DC) systems. The calibration device includes a circuit with a first reference (ref) sensor that has a refinput and a refoutput. The circuit has a first device under test (DUT) sensor with a DUTinput and a DUToutput. The circuit has a coupler, where the refoutput and the DUToutput are connected to a first input and a second input of the coupler respectively and the coupler has a coupler output. A refheating element is adjacent to and electrically isolated from the refsensor and a DUTheating element is adjacent to and electrically isolated from the DUTsensor. A refpower source is connected to the refheating element, and a DUTpower source is connected to the DUTheating element.
