Markers
Markers are tools for numerical readout of measured data and for selecting points on
the trace, or, in general, in the diagram area. A marker is displayed with a symbol (e.g.
a triangle, a crossbar or a line) on the trace, which can be a data trace or a memory
trace. At the same time, the coordinates are displayed in a marker info field or in a
table. Each marker can be defined as a normal marker (M), reference marker (R), or
delta marker (
Δ
M).
●
A normal marker ("M1, M2...") determines the coordinates of a measurement point
on the trace.
●
The reference marker ("R") defines the reference value for all delta markers.
●
A delta marker ("DeltaM1, DeltaM2...") indicates the coordinates relative to the ref-
erence marker.
A special set of markers M1 to M4 is provided for bandfilter search mode.
