3.2 Custom OFDM Measurement
The rules for finding the maximum peak are exactly the same as for Peak Search,
including the use of the peak criteria rules. However, the minimum trace value is not
required to meet any criteria other than being the minimum y-axis value in the trace.
If the selected marker is Off, a Delta type marker is turned on and the peak-to-peak
search is done. If the selected marker is on, but it is not a Delta marker, then it is
changed to Delta, which turns on the reference marker if needed, and then it
performs the peak-to-peak function.

Marker Delta
Pressing this control has exactly the same effect as pressing Delta in "Marker Mode"
on page 478 on the Settings tab. The selected marker becomes a Delta Marker. If
the selected marker is already a Delta marker, the reference marker is moved to the
current position of the selected marker, thus resetting the delta to zero.
The control is duplicated here to allow you to conveniently perform a peak search
and change the marker’s control mode to Delta without having to access two
separate menus.
3.2.7.4 Properties
The controls on this tab are used to set certain properties of the selected marker.
Marker X
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker X" on page 476 on the Settings tab.
Relative To
Selects the marker to which the selected marker is relative (its reference marker).
Every marker has another marker to which it is relative. This marker is referred to as
the “reference marker” for that marker. This attribute is set by Marker, Properties,
Relative To. The marker must be a Delta marker to make this attribute relevant. If it
