Time base

The s/Div and Delay fields are displayed on all of the oscilloscope menus,
except for the Calibration menu.
s/Div field
The s/Div field allows you to set the sweep speed (time scale) on the
horizontal axis of the display from 1 ns/div to 5 s/div. Sweep speed is
measured in seconds per division.
Delay field
The Delay field allows you to set the horizontal position of the displayed
waveform in relation to the trigger. Delay time is always measured from the
trigger point on the waveform to the center of the screen. Delay time is
measured in seconds. When acquisitions are stopped, the Delay field can be
used to control the portion of acquisition memory displayed on screen.
Autoscale Action
