●
Alternatively, change the position of the selected marker using the rotary knob. By
default, the marker is moved from one pixel to the next.
●
You can also set an active marker to a new position by defining its position on the
x-axis numerically. When you select the softkey for a marker, an edit dialog box is
displayed.
●
The most commonly required marker settings and functions are also available as
softkeys or via the context menu. Tap the marker on the touchscreen and hold your
finger for about 2 seconds until the context menu is opened, then select the
required entry.
●
Softkeys for active markers (displayed on the screen) are highlighted blue. The
softkey for the currently selected marker (for which functions are performed) is
highlighted orange.
●
To set individual markers quickly, use the softkeys in the "Marker" menu.
●
To set up several markers at once, use the "Marker" dialog box.
●
To position the selected marker to a special value, use the softkeys in the "Marker
To" menu.
Marker types
All markers can be used either as normal markers or delta markers. A normal marker
indicates the absolute signal value at the defined position in the diagram. A delta
marker indicates the value of the marker relative to the specified reference marker (by
default marker 1).

7.4.1.1 Activating Markers
Only active markers are displayed in the diagram and in the marker table.
By default, marker 1 is active and positioned on the maximum value (peak) of trace 1
as a normal marker. If several traces are displayed, the marker is set to the maximum
value of the trace which has the lowest number and is not frozen (View mode). The
next marker to be activated is set to the frequency of the next lower level (next peak)
as a delta marker; its value is indicated as an offset to marker 1.
A marker can only be activated when at least one trace in the corresponding window is
visible. If a trace is switched off, the corresponding markers and marker functions are
also deactivated. If the trace is switched on again, the markers along with coupled
functions are restored to their original positions, provided the markers have not been
used on another trace.
