  • Patent number: 9618965
    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.

  • Publication number: 20100017157
    Abstract: The embodiments herein provide a device, method and a system to for accurate measurement and analysis of signals. The embodiments provided herein reduce distortions in the signal. The system is configured to center the eye by accurately measuring the skew (between the clock and data signal) and the jitter and then, compensating it from asymmetrical eye plot.
