Perhaps the simplest and most common of microwave instruments is the power meter. It consists of a sensor, which absorbs or detects RF power and converts it to a DC signal, and measurement circuitry, which accurately measures this DC signal and applies correction and calibration factors to it, to produce a reading of the RF power level. Power meters come in a variety of forms and complexities, some of which are noted next.
