N2820A Probes and Dual-Grid View
N2820/1A User’s Guide 19
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.
On the display, the white bounding- area box identifies the
portion of the zoomed- out waveform that is displayed in the
zoomed- in window. This box does not indicate waveform
clipping.
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.
To view only one window, click Setup > Display to open the
Display Setup dialog box and, in the Quantity field, select 1.
NOTE For best measurement results, on the oscilloscope click Setup >
Acquisition and select one of the High Resolution settings.
