ESIB
Receiver - Display and Limit Lines
Entry and Editing of Limit Lines
A limit line is characterized by
• its name
• the domain assignment (frequency)
• the scale in absolute frequencies
• linear or logarithmic interpolation
• the vertical unit
• the vertical scale
• the definition of the limit line as either upper or lower limit.
• the interpolation points for frequency and level
When the limit line is entered, the ESIB immediately checks ll limit lines according to rules that
guarantee correct operation.
• The frequencies for each interpolation point must be entered in ascending order, however, for any
single frequency, two data points may be entered (vertical segment of a limit line).
The interpolation points are allocated in order of ascending frequency. Gaps are not allowed. If gaps
are desired, two separate limit lines must be defined and then both enabled.
• The entered frequencies need not necessarily be selectable in ESIB. A limit line may also exceed the
frequency display range. The minimum frequency for an interpolation point is -200 Hz, the maximum
frequency is 200 GHz.
• The minimum/maximum value for a limit line is -200 dB/+200 dB for the logarithmic or 10 -20 /10 +20 or
-99.9%/+ 999.9% for the linear amplitude scales.
