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 that may vary its position depending on the mea-
surement results, a fixed reference marker can be defined for trace analysis.
When you set the "State" to "On", a vertical and a horizontal red display line are dis-
played, 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 refer-
ence 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.
Alternatively, a Peak Search can be performed to set the current maximum value of
the trace assigned to marker 1 as the fixed reference marker.
If activated, the fixed reference marker ("FXD") can also be selected as a "Reference
Marker" instead of another marker.
