E
Reference value
(for all traces): The
Reference Value
is indicated with a triangle
at the right edge of the diagram and a dashed, horizontal line. The value and
position of the triangle can be changed in order to modify the diagram scale and
shift the trace vertically.
E
Measured quantity (for the active trace): The measured quantity is indicated in the
left upper corner of the diagram.
A trace can be either a data trace, a memory trace, or a mathematical trace; see
Trace
Types
below.
Context menu of the diagram area
A right mouse click on any point of the diagram area (except the marker info field and
the measured quantity info) opens a context menu:
The settings correspond to the most common commands in the

3.1.5.3 Trace Types
The analyzer uses traces to display the current measurement result in a diagram area
but is also capable of storing traces to the memory, recalling stored traces, and
defining mathematical relations between different traces. There are three basic trace
types:
E
Data traces show the current measurement data and are continuously updated as
the measurement goes on. Data traces are dynamic traces.
E
Memory traces are generated by storing the data trace to the memory. It
represents the state of the data trace at the moment when it was stored.Memory
traces are static traces which can be stored to a file and recalled.
E
Mathematical traces are calculated according to a mathematical relation between
constants and the data or memory traces of the active setup. A mathematical trace
that is based on the active data trace is dynamic.
It is possible to generate an unlimited number of memory traces from a data trace and
display them together, see
Data -> Mem
. Markers and marker functions are available
for all trace types.
The trace type of each trace in a diagram area is indicated in the trace list. You can
also make each trace
Invisible
without deleting it.
