The return value is of type string and returns the eye measurement results in csv for-
mat with decimal separator "." and field separator "," (see also
MEASurements).
Note that the full set of measurement results is only available for NRZ modulated gen-
erator signals (see
This command will raise an execution error if the active trace in the selected channel is
not an eye diagram.
