The R&S
FPC1000 has six markers, five of which can be used as either markers or
delta markers. Markers show absolute values, delta markers show values relative to
the first marker (marker 1 or "M1"). The first marker (reference marker) is always a nor-
mal marker.
The horizontal position of a marker is represented by a vertical line which extends from
the top to the bottom of the diagram area (continuous lines for markers and dotted
lines for delta markers). The R&S
FPC1000 also draws a marker icon at the bottom of
the line to indicate the position of the marker ( ). The currently selected marker is indi-
cated by a line drawn around the icon ( ). The icon also contains information about the
marker type: "M" for marker, "D" for delta marker, including the marker number ("M1" to
"M6" and "D2" to "D6").
The vertical position of the marker is represented by a small horizontal line on the trace
itself.

The marker coordinates are also shown in numerical form in the marker list above the
diagram area. The marker list opens when you activate the first marker.

The marker list contains the following information.
●
Marker number and type.
"M" for normal markers, "D" for delta marker, including the marker number ("M1" to
"M6" and "D2" to "D6").
The currently selected marker is surrounded by a colored line.
●
Horizontal position of the marker.
The horizontal position is usually a frequency value.
show the time on the x-axis. Normal markers indicate absolute values, delta marker
the (relative) distance to the first marker (reference marker).
, for example, the frequency for the first marker ("M1") is an absolute
value, while the frequency of the second marker, a delta marker, is displayed as an
offset to the first marker. Because the second marker is located to the left of the
first marker, it is a negative value.
●
Vertical position of the marker.
