Question: Is it possible to check if the quality of the QAM signal is good?

Answer: Yes. To do this you can examine the QAM Constellation Map graphs of the signal.  The constellation maps display QAM constellations visually on the Real/Imaginary Axis. Up to 6970 consecutive constellations can be displayed simultaneously, to give you a good idea of the density of the QAM clouds and hence, the quality of the transmitted QAM signal.  QAM Constellation data can also be exported to a binary file.
