segment the limit line is defined as a straight line connecting two points.
Creating limit lines with minimum effort
Choose one of the following methods to efficiently create and handle limit lines:
• To define a limit line with only a few segments, use Add Segment and edit each segment in the
segment table individually.
• Use the multiselection feature to edit several limit line segments at the same time.
• Select a data or memory trace as a limit line (Import Trace) or import a trace stored in a file
(Import File).
• Save your limit lines to a file so you can re-use or modify them later sessions (Save Limit Line,
Recall Limit Line).
The Define Limit Line dialog contains a table to edit the individual segments of the limit line; see below.
The active trace is indicated in the title bar of the dialog. The three buttons below the table extend or
shorten the segment list.
• Add Segment adds a new segment to the list. The new segment is a copy of the previously active
segment and inserted after that segment. The current segment numbers are adapted. The
analyzer places no restriction on the number of segments in a limit line.
• Delete Segment removes the selected segment from the list.
• Del All Segments clears the entire segment list so it is possible to define or load a new limit line.
The buttons to the right of the table are used to import and export limit line data.
• Recall Limit Line... calls up an Open File dialog to load a limit line from a limit line file. Limit line
files are ASCII files with the default extension *.limit and a special file format.
• Save Limit Line... calls up a Save As... dialog to store the current limit line configuration to a limit
line file. Limit line files are ASCII files with the default extension *.limit and a special file format.
• Import Trace
opens a box to select a trace that can be used to define a limit line.
The box contains all data or memory traces of the active channel. As soon as a trace is selected,
the Properties of Imported Segments dialogwith further global import options is opened.
