ESIB
Analyzer - Main Markers
Marker Functions – MARKER Key Group
The markers are used for marking points on measurement curves (traces), reading out measurement
values and for quickly selecting a screen mode. Preselected measurement routines can be called by
pressing a key in the marker menu. The ESIB has four markers and four delta markers per
measurement window. The currently activated marker can be shifted with the cursor keys, the roll-key or
the softkeys. The softkeys are defined according to the type of display representation selected
(frequency or time domain).
The marker which can be moved by the user is defined as the active marker.
Examples of marker displays:
marker active marker temporary marker
1 3
T1
2
delta 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 values of the active marker (also called marker values) are displayed in the marker
field. In the marker info list, the measurement values from all enabled markers are sorted in ascending
order. The marker info list can be switched off with the MARKER INFO softkey so that only the values
for the active marker are shown.
The summary markers have a special function. They read out the rms or average value of the current
trace or the trace averaged over several sweeps in the marker info list. These markers are not
displayed.
Main Markers– NORMAL Key
The NORMAL key calls a menu which contains all the standard marker functions. The current state of
the markers is indicated by a colored illumination of the softkeys. If no marker is enabled prior to
pressing the NORMAL key, MARKER 1 will be enabled as the reference marker and a peak search on
the trace is carried out (assumption: at least one trace is active). Otherwise, the peak search is omitted
and the entry window for the reference marker is activated.
The marker field in the upper right corner of the display screen shows the marker values, in this case,
the frequency, the level and the currently selected trace.
