Basic Settings
• 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 FSQ 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 FSQ. 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.

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.
Name Enter name.
Domain Select domain.
Unit Select units.
X-Axis Select interpolation
Limit Select upper and lower limit value.
X-Scaling Entry of absolute or relative values for the x-axis
Y-Scaling Entry of absolute or relative values for the y-axis
Margin Entry of margin.
Threshold Entry of vertical threshold (only with relative vertical
scaling)
Comment Enter comments.
Time/Frequency Enter time/frequency for the data points.
Limit/dBm Enter magnitudes for the data points.
