To Zoom On A Section Of The Waveform - Agilent Technologies 54831A User's Quick Start Manual

To zoom on a section of the waveform

1 Click and hold the left mouse button in a blank space within the
waveform display area, then drag the mouse to draw a rectangle around
the areas of interest on the waveform(s). Release the mouse button.
2 Click the mouse once anywhere inside the rectangle drawn in step 1.
How the zoom takes place depends on whether acquisition is running or
stopped. If running, the oscilloscope adjusts vertical scale, vertical offset, sweep
speed, and horizontal position as necessary to best rescale the area you defined
in step 1. If stopped, the oscilloscope does a software magnification of the
waveform.
In either case, a small dialog box appears in the corner of the screen, with a
single "Undo" button; by clicking this button, you will undo the zoom and return
the oscilloscope to its previous settings.
Avoid Overdriving the Vertical Input Amplifiers
When the oscilloscope is running, the input waveform can overdrive the vertical
input amplifiers if you expand the vertical excessively. The result is distortion of
the waveform. Ensure that you select a region that will keep all of the waveform
on the screen vertically.
