All probes by default are added to the waveform during the first trigger and upload operation. If you do not want the waveform to contain all probes, it is simple to remove probes from the viewer.
To remove a probe from the waveform viewer, right-click the scalar or bus to delete in the Name column and select Delete from the pop-up menu. Alternatively, select the signal or bus to delete and press the Delete key. Probe transition data is not actually deleted from memory it is hidden from view when probes are removed.
