Changing the Timebase
The oscilloscope digitizes waveforms by acquiring the value of an input
signal at discrete points. The timebase allows you to control how often the
values are digitized. You can change the timebase using the Time/div front
panel knob in the Horizontal Control group.
Note: As you turn the Time/div front panel knob, the value is displayed
at the lower-center of the display as described in Understanding Display
Information (on page 32).
Zooming Waveforms
You can use the Window Zone option on the Horizontal menu to define a
segment of a waveform to see more detail. The Window timebase setting
cannot be set slower than the Main timebase setting. You can turn the
Horizontal Position and Time/Div front panel knobs to zoom in/out in
Window Zone.
1. Press the HORI MENU front panel button. The Horizon menu is
shown.
2. Press the Win Zone option button.
