Delta Pair
One of the marker types. When selected, a pair of markers will appear on the trace:
Reference Marker (marked by a combination of the marker number and letter "R",
such as "1R") and the Delta Marker (marked by the marker number, such as "1").
Key Points:
You can use the numeric keys, knob or direction keys to set the locations of
the reference marker (selecting "Ref") and the delta marker (selecting "Delta")
respectively.
This is different from the Delta type marker in that you can modify both the
reference (selecting "Ref") and delta (selecting "Delta") points. Additionally,
both the X and Y values of the reference marker are stable for "Delta" marker
during the sweep; but the Y value of the reference marker updates along with
the sweep for "Delta Pair" marker.
Span Pair
One of the marker types. When selected, a pair of markers will appear on the trace:
Reference Marker (marked by a combination of the marker number and letter "R",
such as "1R") and the Delta Marker (marked by the marker number, such as "1").
Key Points:
You can use the numeric keys, knob or direction keys to set the locations of
both the reference marker and delta marker at the same time.
If "Span" is selected, setting the "Span Pair" will keep the center position of
the two markers unchanged and move them towards the two sides (value
increases) or the middle (value decreases).
If "Center" is selected, setting the "Span Pair" will keep the relative distance
between the two markers unchanged and move their center position left
(value decreases) or right (value increases).
This is different from the "Delta" type marker in that you can modify both the
reference marker and delta marker at the same time.
