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 541.

Time
"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 5.8.1, "Stim-
ulus tab", on page 522). 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.
Tip: Sweep time
The minimum sweep time depends on the number of measurement points, the mea-
surement bandwidth, the delay time before each partial measurement and the number
of partial measurements required for each measurement point. The analyzer estimates
this time, based on the current measurement settings.
If the "Stop Time" is smaller than the estimated minimum sweep time, the entered
value is increased automatically.
Equidistance of sweep points
The analyzer tries to keep the time intervals between any two consecutive time sweep
points equal: The time sweep samples are equidistant. Equidistance also holds for
sweeps which range over several channels.
