  • A General Calibration Procedure for Measuring RF

    Abstract: This paper presents a general calibration procedure for probing RF voltages and currents in the time domain with conventional oscilloscopes using a directional coupler. It eliminates the need for a separate power calibration and takes advantage of the large dynamic range of a vector network analyzer during the calibration step.
