Oscilloscope's Zoom Mode
If you're familiar with the
oscilloscope's Zoom Mode, you may
be interested to know that while
Zoom Mode uses software to expand
the zoomed-in waveform, dual-grid
view uses hardware amplification
applied by the probe's high-gain
amplifier.

To Simultaneously View Zoomed-In/Zoomed-Out Waveforms
Figure 15 Displayed Zoom Windows
On the display, the bounding-area box identifies the portion of the
zoomed-out waveform that is displayed in the zoomed-in window.
This is shown in
indicate waveform clipping.
If the border of the bounding-area box is red, this indicates that
output clamping is active. When the border is white, output
clampling is disabled.
Dual-grid view allows simultaneous viewing of high sensitivity and
high dynamic-range inputs. One example of using dual-grid view is
to quickly identify and view a specific pulse and perform a DC
power measurement on that pulse.
