Claim Text:
1. A method for determining jitter and noise of an input signal, comprising: acquiring at least one uncorrelated waveform record by an acquisition unit of the test and measurement instrument; determining a correlated waveform based on the at least one uncorrelated waveform; dividing the correlated waveform into unit intervals; dividing the at least one uncorrelated waveform into unit intervals; measuring a timing displacement (t measuring a voltage displacement (V calculating a horizontal shift (t calculating a vertical shift (V wherein the horizontal shift and the vertical shift are calculated for each unit interval using the following equations: wherein SR V represents a slew rate of the uncorrelated waveform on a vertical portion of the uncorrelated waveform and SR H represents the slew rate of the uncorrelated waveform on a horizontal position of the uncorrelated waveform.
