In Figure 3-3, the signal icons Ch1 and Ch2 show the main settings, and the wave-
forms are displayed in diagrams. All other waveforms are minimized and shown in the
signal icon.
Figure 3-5: Signal label on the signal bar
1 = Vertical scale
2 = Vertical position
3 = Offset
4 = Coupling
5 = Clipping indication is shown if the signal is clipped at the top and/or bottom.
You can also adjust the behavior of the signal bar in various ways, see Chapter 3.4.6,
"Using the signal bar", on page 116.
Trigger position and trigger level (4, 5)
The blue markers show the horizontal position of the trigger and the vertical trigger
level. You can touch and move the trigger markers in the diagram to set the positions.
The trigger point is the zero point of the diagram.
The trigger position can be moved outside the diagram. A red trigger position marker
indicates that the trigger position is not visible.
Reference point (6)
The reference point marks the rescaling center. If you modify the time scale, the refer-
ence point remains fixed on the screen, and the scale is stretched or compressed to
both sides of the reference point.
You can define the position of the reference point (HORIZONTAL), and its time dis-
tance from the trigger point of the diagram (POSITION / REF POINT).
Zoom diagram and zoom area (7, 8)
Zoomed waveforms are shown in separate zoom diagrams, in addition to the waveform
diagrams. On the original waveform diagram, a rectangle indicates the zoomed section
of the waveform - this is the zoom area. You can modify the zoom area by dragging the
rectangle as a whole, and by dragging its edges. To toggle between these modes, tap
the zoom area. You can also set exact positions.
The frames of the zoom area and of the associated zoom diagram have the same
color, different zooms are marked with different colors. So it is easy to assign zoom
area and zoom diagram.
As for waveform diagrams, you can change the name of the zoom diagram. A zoom in
a zoom and coupled zooms are also possible.
For details, see Chapter 7.1, "Zoom", on page 278.
