Understand the Horizontal System
The oscilloscope shows the time per division in the scale readout. Since all active
waveforms use the same time base, the oscilloscope only displays one value for all
the active channels, except when you use Delayed Scan.
The horizontal controls can 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.
Horizontal position changes the point, relative to the trigger, where the waveform
appears on the center of the screen.
The Horizontal Knobs
POSITION: The horizontal POSITION knob adjusts the horizontal position of all
channels and math or REF waveforms. The resolution of this control
varies with the time base.
The oscilloscope digitizes waveforms by acquiring the value of an input
signal at discrete points. The time base allows you to control how often
the values are digitized.
SCALE:
To adjust the time base to a horizontal scale that suits your purpose, use
the horizontal SCALE knob.
The SCALE selects the horizontal time/div (scale factor) for the main or
the Delayed Scan time base. When Delayed Scan is enabled, it changes
the width of the window zone by changing the Delayed Scan time base.
