If “too high” or “too low” appears in line 4 instead of the output symbol rate, the setting of the QAM ranges must
be changed (also see ’Selecting the QAM ranges for operation without Stuffing).
If several different QAM stages are possible, it is advantageous to set the smaller stage (e.g. 64 or 32

In operation mode “Stuffing”, “too high” or “too low” is not displayed; instead of this, an exclamation mark indicates
that either the output symbol rate or the QAM stage must be changed in order to attain correct operation (also see
selection of the output symbol rate in operation mode “PRBS” and “Stuffing” with and without programme filter).
