Radio frequency performance characterization of multi-carrier broadband devices

A notched test signal is generated across a frequency band, the notched test signal includes a plurality of frequency notches, each frequency notch associated with one of a plurality of test frequencies. The notched test signal is provided to a device under test at a plurality of different input power levels. An notched output signal is received from the device under test. The notched output signal is filtered to provide a bandpass response at the plurality of test frequencies to generate a filtered notched output signal. A power level of the filtered notched output signal at each of the plurality of test frequencies is measured. A noise performance metric associated with the device under test is determined based at least in part on the power level of the filtered notched output signal.
