1. A method, comprising: a measurement instrument receiving at one or more inputs thereof at least one victim signal from a device under test (DUT), the victim signal including crosstalk interference from one or more aggressor signals which are not received by the measurement instrument; extracting from the victim signal an ideal data pattern for the received victim signal, where the ideal data pattern does not include inter-symbol interference (ISI), does not include noise, and does not include crosstalk interference to the victim signal; ascertaining from the received victim signal and the ideal data pattern at least the ISI for the victim signal; producing a difference signal as a difference between: (1) the received victim signal; and (2) a sum of the ideal data pattern and the ISI; and ascertaining from the difference signal a residual component of the received victim signal comprising a sum of a noise component and the crosstalk interference from one or more aggressor signals which are not received by the measurement instrument.
