Marker X
See "Marker X" on page 959, 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.

Command
:CALCulate:EVM:MARKer[1]|2|…|12:REFerence <integer>
:CALCulate:EVM:MARKer[1]|2|…|12:REFerence?
Example
:CALC:EVM:MARK:REF 5
:CALC:EVM:MARK:REF?
Notes This command 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”
When queried a single value is returned (the specified marker numbers relative marker)
Couplings If the reference marker is off it is turned on in Normal mode at the delta marker location.
Preset The preset default “Relative To” marker (reference marker) is the next higher numbered marker (current
marker +1). For example, if marker 2 is selected, then it’s default reference marker is marker 3. The
exception is marker 12, which has a default reference of marker 1
Set to the defaults by using Restore Mode Defaults. This is not reset by Marker Off, All Markers Off, or
Preset
State Saved Saved in instrument state
Not affected by Marker Off and hence not affected by Preset or power cycle
