Remote command:

on page 832)
Marker Zoom (span > 0)
Opens an edit dialog box to enter a display range for the zoom. The area around
marker 1 is expanded accordingly and more details of the result can be seen. If no
marker is activated, marker 1 is switched on and set on the largest signal.
The following sweep is stopped at the position of the reference marker. The frequency
of the signal is counted and the measured frequency becomes the new center fre-
quency. The zoomed display range is then configured and the new settings are used
by the R&S
ESRP for further measurements.
If the display has not yet been switched to the new frequency display range and you
press the softkey, the procedure is aborted. If an instrument setting is changed during
this operation, the procedure is also aborted.
This function is not available in I/Q Analyzer mode.

Link Mkr1 and Delta1
The delta marker 1 is linked to marker 1, so if the x-axis value of the marker 1 is
changed, the delta marker 1 will follow on the same x-position. The link is off by
default.
You can set the two markers on different traces to measure the difference (e.g.
between a max hold trace and a min hold trace or between a measurement and a ref-
erence trace).

Basic Marker Functions
●
To open the "Marker" menu, press the [MKR] key.
Marker 1 is activated and positioned on the maximum value of the trace as a nor-
mal marker. If several traces are displayed, the marker is set to the maximum value
(peak) of the trace which has the lowest number (1 to 3) and is not frozen (View
mode). In case a marker is already located there, the new marker is set to the fre-
quency of the next lowest level (next peak).
●
To change marker settings quickly, right-click on the marker in the display (or touch
it for about 1 second). A context-sensitive menu is displayed which corresponds to
the softkey functions available for markers.
●
To configure and activate several markers at once, select the "Marker Wizard" to
open a configuration dialog for all markers.
●
To change to another trace, press the "Marker to Trace" softkey ( "Marker to Trace"
on page 178) and enter the number of the trace on which the marker is to be
placed.
The marker changes to the selected trace, but remains on the previous frequency
or time. If a trace is turned off, the corresponding markers and marker functions are
also deactivated.
