Abstract

A system for dynamically calibrating operational parameters of a Device Under Test (DUT) includes a signal generator for generating a data pattern, a DUT structured to generate a clock signal, an oscilloscope structured to measure margins of the generated clock signal compared to an eye-diagram produced on the oscilloscope from the data pattern, and a calibration unit. The calibration unit can produce a candidate a jitter value for the signal generator, receive a determination from the oscilloscope whether the data pattern generated with the candidate jitter value causes the DUT to produce the generated clock signal within a pre-determined tolerance level, and modify the jitter value accordingly. The calibration unit may also be further structured to generate voltage swing values.
