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 52.
Note that the horizontal scale knob has a different purpose in the Zoom
display. See "To display the zoomed time base" on page 56.
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.
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.
Figure 2 shows the trigger point with the delay time set to 200 µs. The
delay time number tells you how far the time reference point is located
from the trigger point. When delay time is set to zero, the delay time
indicator overlays the time reference indicator.
All events displayed left of the trigger point happened before the trigger
occurred. These events are called pre-trigger information, and they show
events that led up to the trigger point.
Everything to the right of the trigger point is called post- trigger
information. The amount of delay range (pre- trigger and post- trigger
information) available depends on the time/div selected and memory
depth.
The horizontal position 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
