DSOX3024 WAVEGEN Impedance

I don't get it.  If the impedance of the wave generator is fixed, why have the High-Z selection?

1 If the Waveform Generator Menu is not currently displayed on the
oscilloscope's softkeys, press the [Wave Gen] key.
2 In the Waveform Generator Menu, press the Settings softkey.
3 In the Waveform Generator Settings Menu, press the Out Load softkey
and turn the Entry **** to select:
• 50 Ω
• High-Z
The output impedance of the Gen Out BNC is fixed at 50 ohms. However,
the output load selection lets the waveform generator display the correct
amplitude and offset levels for the expected output load.
If the actual load impedance is different than the selected value, the
displayed amplitude and offset levels will be incorrect.
