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
Sweep segments can overlap. The segment list must contain at least 2 distinct fre-
quency points before a segmented frequency sweep can be started.
Instrument settings such as the internal generator power, the measurement (IF) band-
width, and the frequency band of the local oscillator can be set independently for the
individual segments.
Due to this flexibility, segmented frequency sweeps are suitable for any detailed analy-
sis of a DUT at specified frequencies. In a Cartesian diagram, the measurement result
is displayed as a trace over a linear frequency scale ranging from the lowest to the
highest frequency point of all segments. The following example shows a segmented
frequency sweep with 2 segments. The forward transmission parameter S
21
is mea-
sured, and a "dB Mag" scaled y-axis is used. In the frequency range between the
sweep segments, the trace is displayed as a straight line.

ulus power, which can be specified in the "Stimulus" settings (see
The measurement is triggered according to the current trigger settings (see
on page 315). Each trigger event triggers the first partial mea-
surement of a measurement point. The time interval between two consecutive mea-
surements depends on the trigger settings and the sweep parameters (especially the
number of points). Any trigger mode is allowed.
