Abstract :
This paper describes an autocalibrating phase reference standard. Besides classical double direct digital synthesizer (DDS) design, it incorporates a novel phase angle detecting circuitry, which measures phase angle between two channels in real time. A new technique provides reference phase detecting scheme, which is independent of phase angle between two signals
