Results

Measurements were done for delays below 10 ns. An example of the fitting result is plotted in figure 1. The mathematical model overlaps correctly the samples. It is hard to distinguish the two different plots and we can then determine when the pulse occurred with high precision.

The figure 2 represents the results for 500 measurements of the same delay. The standard deviation is around 3 ps. These results were obtained with the experimental setup.
