In the Horizontal control area (Horizontal) on the front panel, press the Horizontal
SCALE knob to switch the adjustment mode between "Coarse" and "Fine" (by default,
it is Coarse). You can also press > More > Fine to enable or disable the fine
adjustment of the horizontal time base.
• Coarse adjustment: Rotate the Horizontal SCALE knob will adjust the
horizontal time base of the waveforms of all channels at 1-2-5 step within the
adjustable range. Rotate it clockwise to reduce the horizontal time base, and
counterclockwise to increase the horizontal time base.
• Fine adjustment: Rotate the Horizontal SCALE knob will adjust the horizontal
time base of the waveforms of all channels with a minor step value within the
adjustable range. Rotate it clockwise to reduce the horizontal time base, and
counterclockwise to increase the horizontal time base.
NOTE
When the delayed sweep is enabled, rotate the Horizontal SCALE knob to adjust the time
base for the delayed sweep. The delayed sweep time base displayed in the center of the screen
will be changed accordingly, as shown in the following figure.
6.2 To Adjust the Horizontal Position
Horizontal position, also called trigger position, refers to the trigger point position of
the waveforms of all channels in the horizontal direction relative to the screen center.
When the waveform trigger point is at the left (right) side of the screen center, the
horizontal position is a positive (negative) value.
While you change the horizontal position, the waveform trigger points and the
displayed waveforms of all channels are moved left and right. The horizontal position
at the right-upper corner of the screen changes accordingly, as shown in the figure
below.
You can adjust the horizontal Position with the following three methods:
• Rotate Horizontal POSITION to adjust the horizontal position of the
waveforms of all channels. When you rotate the knob clockwise, the waveform
