You can select a part of the signal by holding the left mouse button pressed and moving the signal cursor across the signal with the mouse. A selected part will be shown by using inverted colors (black background). If you want to extend the selection to the beginning or to the end of the signal, you can press Home or End keyboard keys during the selection.


During selection, you will see a selected range in a tooltip next to your signal cursor:

If you select some part of a signal as explained above and press the right mouse button, you will also see the exact position and the length of the selected signal part in the context menu. This can be used to measure a part of a signal, for example the difference between two FFT peaks or the duration of a signal part.
