Abstract
A method for operating a data processing system to compute the response of a DUT to a modulated input signal is disclosed. The method includes determining a set of parameters for a first model of the DUT from a plurality of measurements of output values from the DUT, each output value includes a measurement of a gain and phase shift provided by the DUT when the DUT is stimulated with a single tone input signal having a frequency in a frequency range determined by the modulated signal. The method also determines a second model that characterizes noise generated by the DUT at the single tone input signals. A performance parameter for an output signal that would be obtained by applying the modulated input signal to an input of the DUT, and receiving the output of the DUT is then determined from the first and second models.
