New approach for active devices characterization under wideband modulated signals within a coherent stimulus- response network environment

Taking together the Nonlinear Vector Network Analyzer and the Spectrum Analyzer capabilities of a modern network analyzer makes available very accurate vector (IQ) measurements of wideband modulated test signals. As the active DUT (can be power amplifier or frequency converter devices) input and output waves are measured coherently within a calibrated network environment, new insights exhibiting the DUT stimulus/response under modulated signals are demonstrated.
