Adjust trigger position (horizontal delay)
Fingers swipe left and right in the waveform display area, the trigger point
will move horizontally, the
horizontal delay time changes, and the delay time is displayed at the top center of the screen, that is, the distance
between the trigger point and the center line
of the waveform display area is displayed.
Figure 5-7 Horizontal Delay
When the trigger point is located on the left side to the center line
of the waveform display area, the
delay time is displayed as a positive value; When the trigger point is located on the right side to the time
reference point
, and the delay time is displayed as a negative value; the trigger point
overlaps with the
center line
of the waveform display area, and the delay time is zero.
Trigger level
Trigger level is the signal voltage corresponding to the set trigger point. When the trigger level is changed, a
horizontal line will appear temporarily on the screen to tell you the level position (the specific value of the trigger
level is displayed in the upper right corner of the screen), then the horizontal line disappears, the trigger level is
indicated by a small arrow
and the indication icon can be dragged to adjust the trigger level value. The
trigger level is shown in Figure 5-8 (the arrow indicates the trigger level line).
