starts the DLP editor function and allows the most recent item that was being
edited, in the DLP editor buffer, to be accessed again. The item will not be in
the spectrum analyzer user memory until it is processed by the SAVE EDIT
softkey. The DLP editor memory remains intact when the instrument is preset
and when it is powered off.
Front-Panel Key Access: (RECALL] or m
allows you to edit the current limit-line tables by accessing Edit Upper ,
Edit Lower, Edit Up/Low, and Edit Mid/Delt. Use PURGE LIMITS under
any of the above edit menus to dispose of the current limit-line table.
Front-Panel Key Access: [j?i!%Gr)
allows you to view or edit the lower limit-line table. Up to 20 entries are
allowed for the lower limit-line table. With the lower limit-line table format,
the coordinates for the lower limit-line are specified, but none are specified for
the upper limit line. Even if upper limit-line values exist or the values had
been entered as an upper and lower limit-line table, the lower limit-line values
are treated as a separate table from the upper limit-line values. The lower
limit-line entries can have independent frequency (or time) and amplitude
coordinates from upper limit-line table entries.

Mid/Delt
allows you to view or edit the upper and lower limit-line tables simultaneously.
These tables are edited by entering a middle amplitude value and an amplitude
deviation. Up to 20 entries are allowed for the upper and lower limit-line
tables. Like the upper and lower limit-line table format, the mid/delta
limit-line table format provides a means of specifying the upper and lower
limit lines at the same time. Unlike the upper and lower table format, the
amplitude values are specified as a middle amplitude value with a delta (the
upper and lower limit lines are drawn an equal positive and negative distance
from the middle amplitude).
With the mid/delta format the frequency (or time), and the middle amplitude
plus the delta comprise the upper limit line; the frequency (or time), and the
middle amplitude minus the delta comprise the lower limit line. The difference
between the mid/delta and the upper/lower format is the way the amplitude
values are entered; the frequency (time) coordinate begins a segment
regardless of the format chosen. The mid/delta format can be used if the upper
and lower limit lines are symmetrical with respect to the amplitude axis. An
upper and lower amplitude component are specified for every frequency (or
time) component.
