Subjects:	Oscilloscopes, Power amplifiers, Digital modulation, Electric impedance, Electronic amplifiers, Measurement, Measuring instruments
Abstract:	The article focuses on using an oscilloscope to perform load-pull measurements with digitally modulated signals, enabling the characterization of power amplifiers without traditional phase-reference equipment or prior tuner calibration. It explains that this time-domain method extracts key performance metrics such as output power, gain, efficiency, and adjacent channel power ratio directly from captured incident and reflected waveforms.
