Method and system for estimating an eye diagram display of a real signal passing through a data communication channel, according to which decoded symbols of the transmitted real signal are captured, along with their corresponding ADC sample values and sampled at a rate of 1 SPS or more. Then statistic data is collected for each captured sequence of bits/symbols for each particular phase and a synthetic signal is created, based on the collected statistics, using a signal generator that produces samples by randomly creating a bit stream by generating a corresponding one or more samples for any symbol sequences in the bit stream according to the number of collected phases. Interpolation on the corresponding samples is then performed, according to required display time resolution and the synthetic signal is then displayed as a two-dimensional eye diagram image, representing all the statistics collected at all phases. |

1. A method for estimating an eye diagram display of a real signal passing through a data communication channel, comprising:
a) capturing decoded symbols of said real signal, transmitted through said data communication channel, along with their corresponding Analog to Digital Conversion (ADC) sample values, sampled at a rate of at least 1 SPS, where 1 SPS represents sampling at a single phase within a symbol and two or more SPS represent sampling at two or more phases within a symbol, respectively; b) collecting statistics for each captured sequence of bits/symbols for each particular phase; c) creating a synthetic signal, based on the collected statistics, using a signal generator that produces samples by randomly creating a bit stream by generating a corresponding one or more samples for any symbol sequences in said bit stream, according to the number of collected phases; d) performing interpolation on the corresponding samples, according to required display time resolution; and e) displaying said synthetic signal as a two-dimensional eye diagram image representing all the statistics collected at all phases. |
