Claim:
1. A system, comprising: a test and measurement instrument; a memory in the test and measurement instrument capable of storing a probability distribution function (PDF) for an eye diagram; an extrema unit to determine a minimum voltage and a maximum voltage for a mask in the eye diagram at each time during a time duration of the mask in the eye diagram, the mask having a pre-determined time duration and a pre-determined voltage range; a sum unit to calculate a bit error rate (BER) at each time from the PDF using the minimum voltage and the maximum voltage at each time during the time duration of the mask in the eye diagram; and a mask BER unit to determine a BER for the mask in the eye diagram from the BER at each time during the time duration of the mask in the eye diagram.
