3 VMA Mode
3.1 Digital Demod Measurement
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 enable you to conveniently perform a peak search
and change the marker’s control mode to Delta without having to access two
separate menus.
3.1.8.4 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 289 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
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:DDEMod:MARKer[1]|2|…|12:REFerence <integer>
:CALCulate:DDEMod:MARKer[1]|2|…|12:REFerence?
Example
:CALC:DDEM:MARK2:REF 4
:CALC:DDEM:MARK2: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 numbers relative marker)
Couplings If the reference marker is off it is turned on in Fixed or 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 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
