To select a range, press the SHIFT key, hold down the left mouse button, and move the mouse left or right, or press the left or right arrow buttons while pressing the SHIFT key.
The Edit > Select Range… command opens a dialog box for entering a range for measured values. The number of measured values selected is also shown.
Tip
If both vertical auxiliary cursors are shown and no range has been marked, then this dialog box opens with the positions of the two auxiliary cursors. This lets you exactly mark the range between the two auxiliary cursors.
You cannot select a range while recording.
Use this command to clip a section, to zoom in on a range, or to limit the FFT or X/Y graph to the selected range.
