LIMISEG Enter Limit-Line Segment for Frequency
n POINT specifies a limit value for the coordinate point, and no other frequency points, so
that a POINT segment specifies a limit value for a single frequency. For an upper limit line,
a POINT segment is indicated by a line drawn from the coordinate point, to a point that is
vertically off the top of screen. For a lower limit line, a POINT segment is indicated by a line
drawn from the coordinate point, to a point that is vertically off the bottom of screen. The
POINT segment type should be used as the last 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
used automatically. If a visible POINT segment at the right edge of the display is not desired,
add an explicit last point segment (higher in frequency than the stop frequency) to the
limit-line table.
Segments are sorted according to starting frequency. A maximum of 20 segments can be
defined in each of the upper and lower halves of a limit line. When the segment type is
omitted, the last type given (or SLOPE if no previous type has been given) is used.
Use LIMISEG if you want to enter amplitude data in the upper or lower limit lines. If you
want to enter amplitude data as upper and lower amplitude pairs or as mid and delta pairs, use
the SENTER command instead of LIMISEG. Use LIMIMODE to specify entry into the upper
limit-line table or the lower limit-line table. (See line 30 of example.)
