Marker Delta
Pressing this button has the same effect as pressing Delta in "Marker Mode" on
page 1007 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.
3.6.7.4 Properties
The controls on this tab are used to set certain properties of the selected marker.
Marker Frequency
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Frequency" on page 1006 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 the Marker,
Properties, Relative To key. The marker must be a Delta marker to make this
attribute relevant. If it is a Delta marker, the reference marker determines how the
marker is controlled and how its value is displayed. A marker cannot be relative to
itself.
Remote
Command
:CALCulate:OBWidth:MARKer[1]|2|…|12:REFerence <integer>
:CALCulate:OBWidth:MARKer[1]|2|…|12:REFerence?
Example
:CALC:OBW:MARK:REF 2
:CALC:OBW:MARK:REF?
Notes Causes the marker specified with the subopcode to become selected
Range (for SCPI command): 1 to 12. If the range is exceeded, the value is clipped
A marker cannot be relative to itself so that choice is not available, and if sent from SCPI generates
error -221: “Settings conflict; marker cannot be relative to itself”
The query returns a single value (the specified marker number’s relative marker)
Couplings The act of specifying the selected marker’s reference marker makes the selected marker a Delta
marker
