3.8 Set up the Horizontal system
3.8.1 Horizontal control knobs
The oscilloscope shows the time per division in the center of the bottom status bar. The horizontal controls
change the horizontal scale and position of waveforms. The horizontal center of the screen is the time
reference for waveforms. Changing the horizontal scale causes the waveform to expand or contract around
the screen center. The horizontal position knob changes the position of the trigger point relative to the
center of the screen.
The oscilloscope digitizes waveforms by acquiring the value of an input waveform at discrete points. The
time base also controls the sampling rate of this digitizing process.
The sampling rate adjusts
automatically to a value suitable for each selected Time/Div scaling factor. Refer to Appendix C for more
detailed information.
Horizontal POSITION knob : Adjusts the horizontal position of both channels and math waveforms.
The resolution of this control varies according to the horizontal scale factor.
Time/Div knob : Selects the horizontal scale factor for the main or the window time base. When
Window Zone is enabled, it changes the width of the window zone by changing the window time base.
Display scan mode :
When the Time/DIV control is set to 100 ms/div or slower and the trigger mode is set to Auto, the
oscilloscope enters the scan acquisition mode. In this mode, the waveform display updates from left to
right. In this mode, trigger or horizontal position control of waveforms is disabled.

3.8.2 Window Zone
Use the Window Zone option to define a segment of a waveform you want to see in greater detail. The
Window time base setting cannot be set slower than the Main time base setting. Adjust the Horizontal
