A "CW Mode" sweep corresponds to the analysis of a signal over the time with a time
scale and resolution that is determined by the trigger events. In a Cartesian diagram,
the measurement result is displayed as a trace over a linear time scale (like, e.g., in an
oscilloscope). The diagram is similar to the "Time" diagram. The following example
shows a "CW Mode" sweep with a DUT that does not markedly change its transmis-
sion characteristics over the time.
Tip: Sweep time
The time interval between two consecutive trigger pulses must not be smaller than the
minimum measurement time per measurement point. See
"Sweep Time / Auto"
on page 304.

"Time" sweeps, like CW Mode sweeps, are performed at constant frequency and stim-
ulus power, which can be specified in the "Stimulus" settings (see Chapter 9.2.1, "Stim-
ulus Tab" , on page 289). A single sweep extends over a specified period of time,
defined via the "Stop Time" setting. The time intervals between two consecutive sweep
points are calculated according to "Stop Time"/(n - 1) where n is the selected
Number
of Points .
A "Time" sweep corresponds to the analysis of a signal over the time; the function of
the analyzer is analogous to an oscilloscope. In a Cartesian diagram, the measure-
ment result is displayed as a trace over a linear time scale. The following example
shows a "Time" sweep with a DUT that does not markedly change its transmission
characteristics over the time.
