Note
When entering a limit-line segment, the frequency, and amplitude values will
be listed as asterisks (***) until new values are entered. The new segment will
be listed last until both the frequency and amplitude values have been entered.
Once the frequency and at least one amplitude value are entered, the segment
will be sorted into the limit-line table according to frequency.
To edit an existing segment, use SELECT SEGMENT to specify the segment. Then use
SELECT FREQ , SELECT AMPLITUD , or SELECT TYPE to specify the column that you wish
to edit.

spectrum analyzer screen if the measurement sweep is within the limit lines. LIMIT FAIL is
displayed if the measurement sweep is not within the limit lines.
