Abstract
A test system implemented method is for measuring the noise margin of a repeating signal under test (SUT). The method includes determining a digitizer noise of a digitizer channel of the test system, and applying the repeating SUT to the digitizer channel of the test system. An oversampled equivalent-time waveform representation of the repeating SUT is acquired, and then a filtered waveform representation is obtained. A noise margin om of the repeating SUT is determine in accordance with the equation σm=(σc2+σi2−σd2)1/2, where σc is a standard deviation of a maximum amount of gaussian noise that can added to the filtered waveform representation without its symbol error rate (SER) exceeding a target value, σi is a standard deviation of the digitizer noise, and σd is a standard deviation of the noise components removed to obtain the filter waveform representation.
