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.

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.
As a consequence of the limit line rules, the limit check will always pass a DUT if no limit lines are
defined.
