R&S ZNB/ZNBT
Logarithmic interpolation
The analyzer offers a logarithmic interpolation mode that allows you to carry over the
limit line definition to logarithmic sweeps.
While "Show Limit Line" is active, the diagrams display all limit line segments.
Exception: In a segmented frequency sweep with point-based x-axis, gaps between
the segments are minimized. To facilitate the interpretation, the R&S ZNB/ZNBT dis-
plays only the limit line segments which provide the limit check criterion (the "tighter"
limit line at each point). In the example below, this rule results in a single, continuous
lower limit line.
