• To turn on zoom, press the Zoom key. To turn it off, press the Zoom key again.
The waveform display area splits into two regions. The top one is the main window.
The bottom is the zoom window, which represents a software expansion of the
acquired waveform data. A section of the waveform in the main window is
highlighted to indicate the part shown in the zoom window.
The horizontal scale and horizontal position controls now change how the waveform
is shown in the zoom window. The horizontal scale will change the amount of
magnification, while the position will change the part of the waveform in the main
window that is shown in the zoom window.
