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.

Add / Insert / Delete / Delete All
The four buttons below the segment list extend or shorten the list.
●
"Add" adds a new segment to the end of the list.
The added segment covers a possible frequency gap between the preceding seg-
ment and the upper frequency limit of the analyzer. The "Start" frequency of the
new segment is set equal to the "Stop" frequency of the preceding segment. The
"Stop" frequency is equal to the upper frequency limit. The number of points is the
same as the number of points of the preceding segment.
●
"Insert" inserts a new segment before the active segment. The segment numbers
of all segments after the new segment are incremented by one.
The new segment covers a possible frequency gap between the two adjacent seg-
ments. A new segment which is inserted before segment no. 1 starts at the lower
frequency limit of the analyzer. The number of points is the same as the number of
points of the next segment.
●
"Delete" removes the selected segment from the list.
