A number of qualitative comparisons of experimental results on unidirectionalfreak wave generation in a hydrodynamic laboratory are presented in this paper.A nonlinear dispersive type of wave equation, the nonlinear Schr\"{o}dingerequation, is chosen as the theoretical model. A family of exact solutions ofthis equation the so-called Soliton on Finite Background describingmodulational instability phenomenon is implemented in the experiments. It isobserved that all experimental results show an amplitude increase according tothe phenomenon. Both the carrier wave frequency and the modulation period arepreserved during the wave propagation. As predicted by the theoretical model, aphase singularity is also observed in the experiments. Due to frequencydownshift phenomenon, the experimental signal and spectrum lose their symmetricproperty. Another qualitative comparison indicates that the Wessel curves forthe experimental results are the perturbed version of the theoretical ones.
