Marker Stepsize
Defines the size of the steps that the marker position is moved using the rotary knob.
"Standard"
The marker position is moved in steps of (Span/1000), which corre-
sponds approximately to the number of pixels for the default display
of 1001 sweep points. This setting is most suitable to move the
marker over a larger distance.
"Sweep
Points"
The marker position is moved from one sweep point to the next. This
setting is required for a very precise positioning if more sweep points
are collected than the number of pixels that can be displayed on the
screen. It is the default mode.

Defining a Fixed Reference
Instead of using a reference marker whose position can vary depending on the mea-
surement results, you can define a fixed reference marker for trace analysis.
Note that this function is not available in all result displays.
For "State" = "On", a vertical and a horizontal red display line are displayed, marked as
"FXD". The normal marker 1 is activated and set to the peak value of the trace
assigned to marker 1, and a delta marker to the next peak. The fixed reference marker
is set to the position of marker 1 at the peak value. The delta marker refers to the fixed
reference marker.
The "Level" and "Frequency" or "Time" settings define the position and value of the ref-
erence marker. To move the fixed reference, move the red display lines marked "FXD"
in the diagram, or change the position settings in the "Marker Settings" tab of the
"Marker" dialog box.
Peak Search
sets the fixed reference marker to the current maximum value of the
trace assigned to marker 1.
If activated, the fixed reference marker ("FXD") can also be selected as a
