6.1 To Adjust the Horizontal Time Base

Horizontal time base, also called the horizontal scale, refers to the time of each grid in

the horizontal direction of the screen. It is usually expressed in s/div. The range of the

horizontal time base is from 5.00 ns/div to 500 s/div.

While you change the horizontal time base, the displayed waveforms of all channels

are expanded or compressed horizontally relative to the selected time reference
