The impedance measurement device outputs a first AC signal to a phase-locked current generator. The phase-locked current generator generates a second AC signal having a phase that is locked to a phase of the first AC signal and having an amplitude that is representative of a presented impedance having a known impedance value. The phase-locked current generator outputs the second AC signal to the impedance measurement device. The impedance measurement device performs an impedance measurement based on the second AC signal to produce a measured impedance value associated with the presented impedance. The impedance measurement device is calibrated based on the measured impedance value and the known impedance value of the presented impedance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for calibration using impedance simulation","description":"A method and apparatus for calibrating an impedance measurement device are provided.
