The dialog contains a table to edit the individual segments of the sweep range. Use the
to select the columns to be displayed and edited.
●
Sweep segments are allowed to overlap.
●
In contrast to standard frequency sweeps, the start and stop frequency in a sweep
segment must not be different.
So with a segmented sweep you can measure n
1
points at frequency f
1
(in segment
1), n
2
points at frequency f
2
(in segment 2) etc.

Table Columns
The table in the upper part of the "Define Segments" dialog contains an automatically
assigned current number for each segment plus the following editable or non-editable
columns:
●
"On" provides check boxes to activate or deactivate each individual segment.
Sweep points in inactive segments are not measured and not listed in the "Point
List".
●
"Start" is the stimulus (x-axis) value of the first point of the segment.
●
"Stop" is the stimulus (x-axis) value of the last point of the segment.
●
"Points" is the number of sweep points in the segment. A single segment can con-
sist of only one point. If "Points" is set to 1, then the "Stop" frequency is set equal
to the "Start" frequency.
Note: Displayed Columns and Segment-specific Measurement Settings
The remaining columns allow you to replace channel-wide measurement settings by
segment-specific ones. These columns are only displayed – and the corresponding
segment-specific values are only applied – if they are selected in the
.
Note: Limitations for overlapping segments
When overlapping sweep segments are created, the marker functions, trace evaluation
functions, trace search functions and band filter functions are still available. It is possi-
ble, however, that these tools show an unexpected behavior when used in overlapping
sweep segments. The reason is that the assignment of markers to traces in overlap-
ping segments is ambiguous. If you want to analyze a particular segment using mark-
ers, turn "Off" all sweep segments that overlap with this segment.
