ESIB
Receiver - Main Markers
Pressing the current reference marker (MARKER 3) softkey again switches
MARKER 3 off. If at least one marker is enabled, the marker with the smallest
number will be selected as the new reference marker (in the example,
MARKER 1). Switching off the last active marker also deletes are delta markers.
IEC/IEEE bus commands
:CALCulate:MARKer[:STATe] ON | OFF;
:CALCulate:MARKer:X 10.7MHz;
:CALCulate:MARKer:Y?
When several measurement curves (traces) are being displayed, the marker is set
to the maximum value (peak) of the active curve which has the lowest number (1 to
4). In case a marker is already located there, it will be set to the frequency of the
next highest level (next peak).
If a measurement curve is turned off, the corresponding markers and marker
functions are also erased. If the curve is switched on again (VIEW, CLR/WRITE;..),
these markers along with coupled functions will be restored to their original
positions.
A prerequisite for the restoration of the marker positions is that individual markers
have not been used on another measurement curve or that the scan data (start/stop
frequency) have not been changed.
If a marker (or, delta marker) necessary for a marker function is not available, it will
be automatically checked whether or not the enabling of the corresponding marker
is possible (see above). If this is not the case, a warning is issued.
WARNING:
No trace active
The activation of the desired marker function is then not possible.
On the other hand, if the marker can be enabled, a peak search is automatically
performed. Thereafter, the desired marker function can be executed.

MARKER
ZOOM
The MARKER ZOOM softkey zooms 10% of the diagram around the current
marker. It opens at the same time a data entry field which allows to enter any
frequency range which is then displayed
Pressing the softkey again expands the diagram such that only 3 measured values
are represented.
