Description
Each limit-line segment is specified with a starting sweep time, an amplitude, and a segment
type.
Note
If the current limit line table contains limit lines based on frequency (as
opposed to a limit line based on the sweep time), executing LIMISEGT will
clear the current frequency limit line table, and set LIMIREL to OFF
Starting sweep time: When you specify the starting sweep time, you are specifying the
starting sweep time with respect to the sweep time of the spectrum analyzer. For example, if
you specify a starting sweep time of 0, the limit-line segment will start at the left side of the
spectrum analyzer display.
Segment type: The segment type defines how the line segment is to extend from its starting
point to the next segment. The segment types are FLAT, SLOPE, and POINT.
n 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
sweep 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.
w
SLOPE draws a straight line between the coordinate point of the current segment and the
coordinate point of the next segment, interpolating amplitude values for all sweep times
between the two points.
