The Trace menu provides all trace settings and the functions to select, modify and store different traces. In addition the menu provides the marker, search and limit check functions.
A trace is a set of data points that can be displayed together in a diagram area. The trace settings specify the mathematical operations used in order to obtain traces from the collected data. They can be divided into several main groups:
Selection of the measured quantity (S-parameters, wave quantities, ratios, impedances,...)
Conversion into the appropriate display format and selection of the diagram type
Scaling of the diagram and selection of the traces associated to the same channel
Readout and search of particular values on the trace by means of markers
Limit check
The trace settings complement the definitions of the Channel menu. Each trace is assigned to a channel; see Traces, Channels and Diagram Areas. The channel settings apply to all traces assigned to the channel.

The Trace menu contains the following functions and submenus:
Measure selects the quantity to be measured and displayed.
Format defines how the measured data is presented in the graphical display.
Scale defines how the current trace is presented in the diagram selected in the Format submenu.
Trace Select provides functions to handle traces and diagram areas, and assign traces to channels.
Trace Funct(ions) store traces to the memory and perform mathematical operations on traces.
Marker positions markers on a trace, configures their properties and selects the format of the numerical readout.
Search uses markers to locate specific points on the trace.
Marker Funct(ions) define the sweep range, scale the diagram and introduce an electrical length offset using the active marker.
Lines defines limits for measured values and activates the limit check.
