Generator power
The power range defined for a power sweep replaces the internal generator power setting in the Power
Bandwidth Averagesubmenu.
The power corresponds to the actual output power at the test port that supplies the stimulus for the
active channel. The wide range of power stimulus values leaves enough flexibility to include an
attenuation or gain in the test setup.

Time
Time sweeps are performed at constant frequency and stimulus power. The measurement is repeated
over a specified period of time at constant time intervals. The total sweep time is defined via Channel -
Stimulus - Stop; see Stimulus and Sweep Types. The time intervals between two consecutive
measurements are calculated according to <Stop>/(n - 1) where n is the selected Number of Points.
The frequency (CW Frequency) and internal generator power (Source Power) is fixed and entered into
a field which pops up as soon as Time is activated:
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 measurement result is displayed as a trace
over a linear time scale (oscillographic representation). The following example shows a Time sweep
with a DUT that does not change its characteristics in time:
