To adjust the horizontal (time/div) scale
1 Turn the large horizontal scale (sweep speed) knob marked to
change the horizontal time/div setting.
You can also make this adjustment using the touchscreen. See "Access
the Horizontal Menu and Open the Scale/Delay Dialog" on page 54.
Notice how the time/div information in the status line changes.
The
∇
symbol at the top of the display indicates the time reference point.
The horizontal scale knob works (in the Normal time mode) while
acquisitions are running or when they are stopped. When running,
adjusting the horizontal scale knob changes the sample rate. When
stopped, adjusting the horizontal scale knob lets you zoom into acquired
data. See
"Panning and Zooming Single or Stopped Acquisitions" on
page 66.
Note that the horizontal scale knob has a different purpose in the Zoom
display. See
"To display the zoomed time base" on page 71.
To adjust the horizontal delay (position)
1
Turn the horizontal delay (position) knob ( ).
The trigger point moves horizontally, pausing at 0.00 s (mimicking a
mechanical detent), and the delay value is displayed in the status line.
You can also make this adjustment using the touchscreen. See "Drag
Waveforms Left and Right to Change the Horizontal Position" on
page 46 and "Access the Horizontal Menu and Open the Scale/Delay
Dialog" on page 54.
Changing the delay time moves the trigger point (solid inverted triangle)
horizontally and indicates how far it is from the time reference point
(hollow inverted triangle
∇
). These reference points are indicated along
the top of the display grid.
