1. A controller, comprising:
an input configured to be coupled to a device under test; and
an output configured to be coupled to the device under test, wherein the controller is configured to:
generate a test signal;
output the test signal to the device under test;
receive a response signal from the device under test;
determine a plurality of bin powers of a plurality of bins, respectively, of a frequency domain signal representative of the response signal; and
determine a figure of merit for the device under test based on a first bin power of a first bin of the plurality of bin powers, wherein the first bin corresponds to a frequency of the test signal.
