Normal
POS
A Normal marker can be moved to any point on the X Axis by specifying its X Axis value. Its
absolute Y Axis value is then the value of the trace point at that X Axis value
Delta
DELT
In Delta mode, the marker result shows the relative result between the selected (Delta) marker
and its reference marker. A Delta marker can be moved to any point on the X Axis by specifying
its X Axis offset from a reference marker. Its absolute Y Axis value is then the value of the trace
point at that X Axis value
Fixed
FIX
A Fixed marker is fixed in the sense that it stays where you place it. It can be directly moved in
both X and Y. It can be moved by a Peak Search. It can also be indirectly moved by re-zeroing
the delta, if it is a relative marker. If it is moved, it again becomes fixed at the X Axis point it
moved to and it has a Y-axis result that it took on when it moved there. If a Normal or Delta
marker is changed to Fixed, it becomes fixed at the X Axis point it was at, and with the Y-axis
result it had when it was set to Fixed
In Fixed mode, the marker result shows:
–
If no Marker Function is on, the absolute X Axis and Y axis value of the marker
–
If a Marker Function is on, the X Axis value and the Y-axis function result the marker had
when it became Fixed
Off
OFF
Turns off the marker, removes the marker annunciation from the display, turns off any active
function and any marker function, and resets the following properties to their default value:
–
X Axis scale: Auto
–
Band Span: 0
–
Auto Trace: On
Off does not affect which marker is selected
Setting Fixed Marker Values
Normal markers
When an X Axis value is entered, or set using the knob or step keys, the marker
moves to the trace point nearest to that X Axis value. The value is retained in all its
precision whether it is at the center of a trace point or not, and future increments are
applied to that value.
Delta markers
When the Delta control is selected:
–
If the selected marker was not already in Delta mode:
