The trace can be complemented by the following display elements, plotted with the

same color:

●

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.

●

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" on page 57.

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 "Display – Area Select"

and "Display – Config View" menus.

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 defin-

ing mathematical relations between different traces. There are three basic trace types:

●

Data traces show the current measurement data and are continuously updated as

the measurement goes on. Data traces are dynamic traces.

●

Memory traces are generated by storing the data trace to the memory. They repre-

sent 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.

●

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. 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.
