1. A method, comprising:
generating a notched test signal across a frequency band, the notched test signal comprising a plurality of frequency notches, each frequency notch associated with one of a plurality of test frequencies;
providing the notched test signal to a device under test;
receiving a notched output signal from the device under test; and
determining a noise performance metric associated with the device under test based at least in part on one or more power levels at the test frequencies of the notched output signal.
