The EDIT LIMIT LINE and NEW LIMIT LINE softkeys both call the EDIT LIMIT LINE
submenu used for editing limit lines. In the table heading, the characteristics of the
limit line can be entered. The data points for frequency/time and level values are
entered in the columns.

Domain, unit, X scaling and Y scaling cannot be modified as soon as reference
values have been entered in the data section of the table.

The frequencies/times for each data point must be entered in ascending order,
however, for any single frequency/time, two data points may be input (vertical
segment of a limit line).
The data points are allocated in order of ascending frequency/time. Gaps are not
allowed. If gaps are desired, two separate limit lines must be defined and then
both enabled.
The entered frequencies/times need not necessarily be selectable in R&S ESU. A
limit line may also exceed the specified frequency or time domains. The minimum
frequency for a data point is -200 GHz, the maximum frequency is 200 GHz. For
the time domain representation, negative times may also be entered. The valid
range is -1000 s to +1000 s.
The minimum/maximum value for a limit line is -200 dB to +200 dB for the
