When you use the front panel Zoom button, a new Zoom trace is created for
every open trace, showing a 10x magnification of the source trace.
The zoomed portion of the source trace is highlighted, so that the area
corresponding to the zoom is more visible.
Zoom traces (Z
n
) display a magnified portion of another trace. Any trace can be zoomed, although Zoom is most useful for channel traces, as it allows you to
see the source at the original Timebase at the same time as the Zoom "close up."
