Horizontal Scale
Horizontal scale, namely horizontal time base, refers to the time per grid in the
horizontal direction on the screen and is usually expressed as s/div.
Being similar to “Vertical Scale
”, the horizontal scale can be adjusted in “Coarse” or
“Fine” mode. Press MENU  ScaleAdjust in the horizontal control area
(HORIZONTAL) at the front panel to select the desired mode.
 Coarse: set the horizontal scale in 1-2-5 step namely 1 ns/div, 2 ns/div, 5 ns/div,
10 ns/div……1.000 ks/div (taking adjusting MSO2302A counterclockwise as an
example).
 Fine: further adjust the horizontal scale at a relatively smaller step.
After the adjustment mode is selected, turn HORIZONTAL
SCALE to adjust the
horizontal scale. Turn clockwise to reduce the horizontal scale and turn
counterclockwise to increase. The scale information at the upper left corner of the
screen will change accordingly during the adjustment. The range of horizontal scale
adjustment is related to the model of the oscilloscope as shown in the figure below.
Table 3-1 Range of Horizontal Scale
Models Range of Horizontal Scale
MSO2302A/MSO2302A-S/DS2302A/DS2302A-S 1.000 ns/div to 1.000 ks/div
MSO2202A/MSO2202A-S/DS2202A/DS2202A-S 2.000 ns/div to 1.000 ks/div
MSO2102A/MSO2102A-S/DS2102A/DS2102A-S 5.000 ns/div to 1.000 ks/div
MSO2072A/MSO2072A-S/DS2072A/DS2072A-S 5.000 ns/div to 1.000 ks/div
When adjusting the horizontal scale, the waveform will be expanded or compressed
around the center of the screen, the trigger position or the user-defined position
according to the change of the horizontal scale.
