•
Points is the number of sweep points in the segment . A single segment can consist of only one
point, however, the entire sweep range must contain at least 2 distinct frequency points. If
Points is set to 1, then the Stop frequency is set equal to the Start frequency.
•
The remaining columns show the channel settings for each segment. They are displayed only if
they are selected in the
Individual Segment Settings panel.
When a new segment is defined or when the stimulus range of a segment is modified, the
analyzer automatically checks whether it is compatible with the existing segments. The Start and
Stop values of the existing segments are modified so that there is no overlap between any of the
segments. If this is not possible (e.g. because of the limited frequency range of the analyzer),
the entry of the new Start or Stop value is denied.
Use the paste marker list for convenient entry of Start and Stop values.

The commands in the
[SENSe<Ch/Tr>:]SEGMent...
subsystem define all sweep
segment settings.
Inserting and Deleting Segments
Three buttons on the left side below the table in the Define Segments dialog extend or shorten the
segment list:
•
Insert New Segment
adds a new segment to the list. The new segment is inserted after the active segment. The
segment numbers (#) of all segments after the new segment are adapted.
To avoid overlapping segments, the new segment ranges from the Stop value of the previously
active segment to either the Start valueof the next segment or the maximum frequency of the
analyzer. The analyzer places no restriction on the number of segments in a sweep range.
•
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
segmented sweep range.

Individual Segment Settings
The options in the Individual Segment Settings panel can be used to vary the channel settings of every
individual segment in the list.
The first sweep segment is created with the channel settings defined for general sweep types. When
any further sweep segment created, it uses the channel settings of the previously active segment. Each
selected (checked) option adds a column to the segment list.
