Log Freq
In a "Log Freq" sweep, the stimulus frequency is swept on a logarithmic scale over the
continuous frequency range. The frequency range (sweep range) and the internal gen-
erator power can be specified in the "Stimulus" settings (see Chapter 5.8.1, "Stimulus
tab", on page 414). The sweep points are calculated from the "Span" and the specified
"Number of Points" (n > 1) with the condition that the step width is constant on the log-
arithmic scale.
"Log Freq" sweeps are suitable for the analysis of a DUT over a large frequency range,
e.g. over several octaves. In a Cartesian diagram, the measurement result is displayed
as a trace over a logarithmic frequency scale. The following example shows a "Log
Freq" sweep with the forward transmission parameter S
21
as measured quantity, and a
"dB Mag" scaled y-axis.
Tip: In "Log Freq" representation, limit lines and ripple limit lines appear as exponential
curves; see Chapter 4.4.1.1, "Rules for limit line definition", on page 145.

Segmented
In a "Segmented" (linear) frequency sweep, the sweep range can be composed of sev-
eral continuous frequency sub-ranges or single frequency points. The sub-ranges are
termed sweep segments and are defined in the Define Segments dialog.
