Coupling of Delta and Reference markers
The following coupling rules apply from the front panel and also if the equivalent
SCPI commands are sent.
Pressing the Delta key causes the selected marker to become a delta marker if it is
not already. Also, the selected marker's reference is affected as follows:
–
If the reference marker was off, it is turned on as a fixed marker.
–
The reference marker is moved to the trace of the selected marker and set to the
same position as the selected marker.
–
If the delta marker has a marker function turned on, the reference marker takes
on the same function (with the same band limits).
Exception: Pressing Delta when the selected marker's mode is not yet Delta does no
t move or change a reference marker that is already turned on (Normal, or Delta)
and on the same trace as the selected marker. It merely changes the selected
marker's mode to Delta and shows the current offset between it and the reference. If
you press Delta again (when the selected marker is already in Delta mode) then the
reference is moved and modified as described above.
When a delta marker is changed to any other control mode, if its reference marker is
fixed then the reference marker is also turned off.
If you move a delta marker to a different trace, it is forced to Normal mode and if its
reference is fixed, the reference is turned off.
A delta marker is forced to Normal mode if you turn its reference off or if you move
its reference to another trace. (In the latter case the reference is not turned off even
if it is fixed.)
If you change the selected marker's reference (using the Marker, Properties,
Relative To), the selected marker is forced to Delta mode. This change of the
