Selecting the Segment Type
Press SEGMENT TYPE , then FLAT, SLOPE, or POINT to specify the segment type. The segment
type determines how to connect the coordinate point of the current line segment with the
coordinate point of the next line segment. The segment type determines whether the line
segment is horizontal, vertical, sloped, or a single point. The three segment types are:
1. Flat draws a zero-slope line between the coordinate point of the current segment and the
coordinate point of the next segment, producing limit-line values equal in amplitude for all
frequencies or times between the two points. If the amplitude values of the two segments
differ, the limit-line will “step” to the value of the second segment (see Figure 5-7).
2. Slope draws a straight line between the coordinate point of the current segment and the
the two points.
3. Point specifies a limit value for the coordinate point. It specifies a limit at a single frequency
indicated by a line drawn from the coordinate point, vertically off the top of screen. For a
lower limit line, a point segment is indicated by a line drawn from the coordinate point,
segment in the limit-line table. However, if the last segment in the table is not specified as
the point segment type, an implicit point is automatically used. (If a visible point segment at
limit-line table that is higher in frequency than the stop frequency.)
Figure 5-7 demonstrates the different segment types.
