MA RKER
NORM DELTA
MARKER 1
MARKER 4
The MARKER 1/2/3/4 .softkey selects the corresponding marker and activates it.
MARKER 1 is always the normal marker. After they have been switched on,
MARKERS 2 to 4 are delta markers that refer to MARKER 1 . These markers can
be converted into markers with absolute value display by means of the MARKER
NORM DELTA softkey. When MARKER 1 is the active marker, pressing the
M ARKER NORM DELTA softkey switches on an additional delta marker.
Pressing the MARKER 1 to 4 softkey again switches off the selected marker.
Example:
[ PRESET ] R&S FSMR is set to the default setting.
[ MKR ] On calling the menu, MARKER 1 is switched on ('1' high-
lighted in the softkey) and positioned on the maximum value
of the trace. It is a normal marker and the
MARKER
NORMAL softkey is highlighted.
[ MARKER 2 ] MARKER 2 is switched on ('2' highlighted in the softkey). It is
automatically defined as a delta marker on switching on so the
DELTA is is
highlighted on softkey MARKER NORM DELTA . The fre-
quency and level of MARKER 2 with reference to MARKER
1 are output in the marker info field.
[MARKER
NORM DELTA]
The MARKER NORM DELTA softkey is highlighted.
MARKER 2 becomes a normal marker. The frequency and
level of MARKER 2 are output as absolute values in the
marker info field.
[MARKER 2] MARKER 2 is switched off. MARKER 1 is the active marker
for entry. The frequency and level of MARKER 1 are output
in the marker info field.
IEC/IEEE-bus command:
CALC:MARK ON;
CALC:MARK:X <value>;
CALC:MARK:Y?
CALC:DELT ON;
CALC:DELT:MODE ABS|REL
CALC:DELT:X <value>;
CALC:DELT:X:REL?
CALC:DELT:Y?
When several traces are being displayed, the marker is set to the maximum value (peak) of the active
trace which has the lowest number (1 to 3). In case a marker is already located there, it will be set to the
frequency of the next lowest level (next peak).
When the split-screen display mode is active, the marker will be placed in the active window. A marker
can only be enabled when at least one trace in the corresponding window is visible.
If a trace is turned off, the corresponding markers and marker functions are also deactivated. If the trace
is switched on again (
VIEW , CLR/WRITE ;..), the markers along with coupled functions will be restored
to their original positions provided the markers have not been used on another trace.
