The context menu provides the following functions:
•
Modification of all entries in the segment table: Type, start and stop values for the stimulus and
response variable.
•
Definition of an offset for response and stimulus values in analogy to the
Properties of Imported
Segments
dialog.
•
Delete
the selected segments.
•
Merge
the selected segments to a single new segment. The start and stop values of the new
segment are given by the start values of the first selected segment and the stop value of the last
selected segment. The type is taken from the first selected segment. The new segment replaces
the selected segments.
Remote control:
CALCulate<Chn>:LIMit:UPPer...
CALCulate<Chn>:LIMit:LOWer...
Rules for Limit Line Definition
The analyzer places very few restrictions on the definition of limit line segments. The following rules
ensure a maximum of flexibility:
•
Segments don't have to be sorted in ascending or descending order (e.g. the
Start Stimulus
value
of segment no. n doesn't have to be smaller than the
Start Stimulus
value of segment no. n+1).
•
Overlapping segments are allowed. The limit check in the overlapping area refers to the tighter
limit (the pass test involves a logical AND operation).
•
Gaps between segments are allowed and equivalent to switching off an intermediate limit line
segment.
•
Limit lines can be partially or entirely outside the sweep range, however, the limits are only
checked at the measurement points.
The following figure shows a limit line consisting of 3 upper and 2 lower limit line segments. To pass the
limit check, the trace must be confined to the shaded area.
