displays any portion of the limit lines that are currently within the spectrum
analyzer display boundary. If Y (yes) is underlined the limit lines are displayed.
If N (no) is underlined they are not displayed. If AUTO is underlined, the
display of the limit lines is dependent on LMT TEST. The limit lines will be
displayed while the limit test function is turned on, otherwise they will be
turned off.
Limit lines cannot be displayed while using the analog+ display mode. Limit
testing can be done but the limit lines will not be displayed.
