Using limit-line Functions
Selecting the Segment
Number
Pressing SELECT SEGMENT specifies the segment number to be entered or
edited. Limit lines are created by entering frequency or time values and
amplitude values into a limit-line table. The frequency/time and amplitude
values specify a coordinate point from which a limit-line segment is drawn.
The coordinate point is the lowest frequency or time point of the line
segment. Limit lines are constructed from left to right. The segment is
defined by its beginning point. See Figure 3-6.
NOTE
Up to 20 segments can be specified for an upper or lower limit-line table.
When entering a limit-line segment, the frequency/time and amplitude values will be listed as asterisks
I***)
until new values are entered. The new segment will be listed last until both the frequency for
time) and the amplitude values have been entered. Once the frequency/time and an amplitude value
are entered, the segment will be sorted into the limit-line table according to frequency or time.
