"Normal"
A normal marker indicates the absolute value at the defined position
in the diagram.
"Delta"
A delta marker defines the value of the marker relative to the speci-
fied reference marker (marker 1 by default).
Remote command:
CALCulate<n>:MARKer<m>[:STATe]
CALCulate<n>:DELTamarker<m>[:STATe]
Reference Marker
Defines a marker as the reference marker which is used to determine relative analysis
results (delta marker values).
If the reference marker is deactivated, the delta marker referring to it is also deactiva-
ted.
If a fixed reference point is configured (see
the reference point ("FXD") can also be selected instead of another marker.
Remote command:
CALCulate<n>:DELTamarker<m>:MREFerence
Linking to Another Marker
Links the current marker to the marker selected from the list of active markers. If the x-
axis value of the initial marker is changed, the linked marker follows to the same posi-
tion on the x-axis. Linking is off by default.
Using this function you can set two markers on different traces to measure the differ-
ence (e.g. between a max hold trace and a min hold trace or between a measurement
and a reference trace).
Remote command:
CALCulate<n>:MARKer<ms>:LINK:TO:MARKer<md>
CALCulate<n>:DELTamarker<ms>:LINK:TO:MARKer<md>
CALCulate<n>:DELTamarker<m>:LINK
Assigning the Marker to a Trace
The "Trace" setting assigns the selected marker to an active trace. The trace deter-
mines which value the marker shows at the marker position. If the marker was previ-
ously assigned to a different trace, the marker remains on the previous frequency or
time, but indicates the value of the new trace.
If a trace is turned off, the assigned markers and marker functions are also deactiva-
ted.
Remote command:
Select Marker
The "Select Marker" function opens a dialog box to select and activate or deactivate
one or more markers quickly.
