In all cases, the zoomed channels are displayed in a separate half-height
grid at the bottom of the display (separate from the channels). If you also
have a Math trace showing when you zoom, three grids are then shown on
the display, each at one-third height.
Comparison is made easy as the zoomed traces are nearly the same color
as the original channel traces. The zoomed area is shown in white on the
original channel trace. All zooms share a common horizontal zoom scale
and position. Each zoom has an independent vertical zoom capability. All
zooms are calculated to 16-bit vertical resolution. Therefore, you can
vertically scale the zoom traces and still maintain very high resolution when
viewing signal detail.
Creating Zooms
There are three ways to create zooms of your channels.

You can draw a box around the area that you wish
to zoom simply by dragging your finger, stylus, or
mouse pointer around the area of the waveform or
waveforms that you want to zoom. Zoom traces are
created instantly in a separate grid.
UNDO your zoom by touching the UNDO button in
the upper-right corner of the display.
You can also use touch screen zoom to change the
zoom scale of an existing Zoom, Math, or Memory
(reference waveform) trace.
When you zoom a waveform by this method, a
representation of the zoom area appears in a
thumbnail Preview in the Zx dialog (lower-right).
