marker more precisely, change the step size to move from one sweep point to the
next (General Marker Setting).
●
You can also set an active marker to a new position by defining its x-position
numerically. When you select the softkey for a marker, an edit dialog box is dis-
played.
●
The most commonly required marker settings and functions are also available as
softkeys or via the context menu. Tap the marker on the touch screen 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 very 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.
●
To determine more sophisticated marker results, use the special functions in the
"Marker Function" dialog box.
In addition to basic markers, sophisticated marker functions are provided for special
results such as noise or band power measurements.

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).
In addition, special functions can be assigned to the individual markers. The availability
of special marker functions depends on whether the measurement is performed in the
frequency or time domain, and on the type of measurement.
Temporary markers are used in addition to the markers and delta markers to analyze
the measurement results for special marker functions. They disappear when the asso-
ciated function is deactivated.
6.9.1.2
Activating Markers
Only active markers are displayed in the diagram and in the marker table.
Active markers are indicated by a highlighted softkey.
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
