ESIB
Analyzer - Display and Limit Lines
Entering and Editing of Limit Lines
A limit line is characterized by
• its name
• the domain assignment (frequency or time)
• whether the scale is absolute or relative (time or frequency)
• linear or logarithmic interpolation
• the vertical unit
• the vertical scale
• the definition of the limit line as either an upper or lower limit.
• the interpolation points for frequency/time and level
When the limit line is entered, the ESIB immediately checks all limit lines according to rules that
guarantee correct operation.
• The frequencies/times for each interpolation point must be entered in ascending order, however, for
any single frequency/time, twodata points may be entered (vertical segment of a limit line).
The interpolation 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 capable of selection on the ESIB. A limit line
may also exceed the frequency or time display range. The minimum frequency for an interpolation
point is -200 GHz, the maximum frequency is 200 GHz. For the time domain, negative times may also
be entered. The range is -1000 s to +1000 s.
• The minimum/maximum value for a limit line is -200 dB/ +200 dB for the logarithmic scale or 10 -20 /
10 +20 or-99.9%/ + 999.9% for linear amplitude scales.
