●
Selected
Selects one of the markers. The currently selected marker is highlighted in orange
color. The label indicates the marker type and its number.
●
State
Turns the marker on and off.
●
Type
Selects the marker type.
The first marker always is a normal marker (abbreviated 'N'). Normal markers
determine absolute signal levels. In the diagram area, they are drawn as a triangle
pointing up ( ).
If you add more markers, these will be delta markers by default (abbreviated 'D').
Delta markers show signal levels in relation to another (normal) marker, by default
in relation to the first marker. If necessary, you can still change the reference
marker in the "Ref" column. In the diagram area, delta markers are drawn as a tri-
angle pointing down ( ).
When performing EMI measurements however, you usually want to have absolute
marker readouts for all markers that you are using.
●
Ref
Selects the reference marker for delta markers.
By default, the reference marker for all delta markers is the first marker.
This is active only for delta markers.
●
Trace
Selects the trace number the marker is positioned on.
You can place markers on any of the active traces. The R&S FSV-K54 supports the
use of up to four traces.
