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:WAVeform:MARKer[1]|2|…|12:REFerence <integer>
:CALCulate:WAVeform:MARKer[1]|2|…|12:REFerence?
Example
:CALC:WAV:MARK:REF 8
:CALC:WAV:MARK:REF?
Notes This command causes the marker specified with the subopcode to become selected
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 number’s relative marker)
Couplings The act of specifying the selected marker’s reference marker makes the selected marker a Delta
marker
If the reference marker is OFF, it is turned on in POSition 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 its default reference marker is Marker 3. The
exception is Marker 12, which has a default reference of Marker 1
Set to default by Restore Mode Defaults. 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
Range 1 to 12
Remote Command only: if the range is exceeded, then the value is clipped
Min 1
Max 12
Annunciation Appears in the marker label of a Delta marker
Marker Trace
Assigns the specified marker to the designated trace.
