Complex Spectrum:
:CALCulate:SPECtrum:MARKer[1]|2|…|12:REFerence <integer>
:CALCulate:SPECtrum:MARKer[1]|2|…|12:REFerence?
Streaming:
:CALCulate:STReaming:MARKer[1]|2|…|12:REFerence <integer>
:CALCulate:STReaming:MARKer[1]|2|…|12:REFerence?
Example
:CALC:SPEC:MARK6:REF 8
:CALC:SPEC: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”
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
Min 1
Max 12
Annunciation Appears in the marker label of a Delta marker
Marker Trace
Selects the trace on which you want your marker placed. A marker is associated with
one and only one trace. This trace is used to determine the placement, result, and X-
Axis Scale of the marker. All markers have an associated trace; it is from that trace
that they determine their attributes and behaviors, and it is to that trace that they go
when they become POSition or DELTa markers.
Specifying a Marker Trace manually or with this command associates the marker
with the specified trace and turns Auto Initialize OFF for that marker. If the marker is
not OFF, it moves the marker from the trace it was on to the new trace. If the marker
is OFF, it stays off but is now associated with the specified trace.
The query returns the name of the trace (one of: SPECtrum, ASPectrum, I, Q, IQ) on
which the marker is currently placed, even if that marker is in Auto mode.
