Selecting the Marker Type
When you add new markers, they are delta markers by default. Their coordinates are
relative to the first marker (M1). You can turn delta markers into normal markers if you
need absolute information about the marker position.
1. Select the delta marker you want to convert in the
Measurement Result View
.
The selected marker is highlighted in the
Measurement Result View
and its corre-
sponding label in the trace window turns focus with a blue frame around the marker
label. The R&S Cable Rider ZPH opens a marker input field.
Alternatively, you can press the [MARKER] key to select the delta marker you want
to convert with the "Select Marker" softkey
2. Select the "Marker Type" softkey.
The delta marker turns into a normal marker. Its label changes accordingly (e.g. D2
to M2) and its coordinates are now absolute values.

est level value of the trace, relative to its current position.
