4.2     Known limitations

·       QProny module may fail to provide correct models for one-port.

·       Only the automatic model order selection is available. The highest oversampling factor for the signal is 256. Consequently, if extremely fine meshes are used causing the waveforms to be sampled at more than 256 points per wavelength, the quality of the modelling may deteriorate.

·       The module may fail if there is not sufficient amount of memory available in the system. Processing of more than 200k samples may require over 20MB of RAM in addition to the memory used by QuickWave-3D.

·       Postprocessing can take several minutes when over 50 000 samples are to be analysed.
