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
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.
Tip: You can change to point based x-axis to improve the display of a segmented fre-
quency sweep (see

Power
In a "Power" sweep, the internal generator power is swept in dB-linear, equidistant
steps over a continuous power range. The generator power range (sweep range) and
the fixed frequency can be specified in the "Stimulus" settings (see
"Stimulus
"Power" sweeps are particularly suitable for the analysis of non-linear effects (satura-
tion, compression) on active and passive DUTs (e.g. power amplifiers, mixers).
In a Cartesian diagram, the measurement result is displayed as a trace over a dB-lin-
ear power scale. The following example shows a "Power" sweep in the source power
range between –25 dBm and 0 dBm, performed at a CW frequency of 1 GHz.
