Markers and Delta Markers – MKR Key
The markers are used for marking points on traces, reading out measurement results and for quickly
selecting a display section. R&S ESCI provides four markers per display window. All markers can be
used either as markers or delta markers. The availability of marker functions depends on whether the
measurement is performed in the frequency, time or level domain.
The marker that can be moved by the user is defined in the following as the active marker.
Examples of marker display:
1 3
2
T1
Delta marker
Marker Active marker Temporary marker
Temporary markers are used in addition to the markers and delta markers to evaluate the measurement
results. They disappear when the associated function is deactivated.
The measurement results of the active marker (also called marker values) are displayed in the marker
field. The marker info field at the upper right of the display shows the marker location (here, frequency),
the level and the currently selected trace [T1].
MARKER 1 [T1]
123.4567 MHz
-27.5 dBm
The MKR key calls a menu that contains all marker and delta marker standard functions. If no marker is
active, MARKER 1 will be enabled and a peak search on the trace carried out. Otherwise, the data entry
for the marker activated last is opened.
