R&S ESCI Limit Lines
1166.6004.12 4.187 E-1
Entry and Editing of Limit Lines
A limit line is characterized by
• its name
• the assignment of domain (frequency or time)
• the scaling in absolute or relative times or frequencies
• the vertical unit
• the interpolation
• the vertical scaling
• the vertical threshold (only with relative vertical scaling)
• the margin
• the definition of the limit line as either upper or lower limit.
• the data points for frequency/time and level
At the time of entry, the R&S ESCI immediately checks that all limit lines are in accordance with certain
guidelines. These guidelines must be observed if specified operation is to be guaranteed.
• 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 ESCI. 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 logarithmic or 10
-20
to
10
+20
or -99.9% to + 999.9% for the linear amplitude scales.
