摘要: A method for measuring noise parameters includes generating a noise signal at a noise source. The noise signal includes a first input signal at a first frequency and a second input signal at a second frequency. The first input signal and the second input signal are modulated onto a carrier to generate a modulated signal. The modulated signal is attenuated to a desired power level and applied to a device under test to obtain a noise measurement.
