 Lin. Frequency is the default sweep type. The stimulus frequency is swept in equidistant steps
over the continuous frequency range. In a Cartesian diagram, the x-axis is a linear frequency axis.
 Log. Frequency is analogous to Lin. Frequency, however, the frequency is swept in equidistant
steps on a logarithmic scale. In a Cartesian diagram, the x-axis is a logarithmic frequency axis.
 Segmented Frequency is analogous to Lin. Frequency but uses a sweep range that can be
composed of several continuous frequency ranges or single frequency points defined via Define
Segments. A valid segment list must be defined before activating Segment Frequency.
 Power sweeps are performed at constant frequency but with variable generator power that is
swept in linear, equidistant steps over a continuous range. In a Cartesian diagram, the x-axis is a
dB-linear power axis.
 Time sweeps are performed at constant frequency and stimulus power. The measurement is
repeated over a specified period of time at constant time intervals.
 CW Mode is a variant of the Time sweep where the individual measurements are triggered
according to the current trigger settings.
 Pulse Profile, Define Pulse Profile and Show Pulse Profile Settings control the pulsed sweep
mode (with option R&S ZVA-K7).
 Amplitude Imbalance and Phase Imbalance activate special sweep types for the true differential
mode (with option R&S ZVA-K6).
 Pulse Generator turns the pulse generator on or off.
 Def Pulse Generator defines the properties of the pulse generator signals.
Lin. Frequency
In a Lin. Frequency sweep the stimulus frequency is swept in equidistant steps over the continuous
frequency range. The frequency range (sweep range) is defined with the Stimulus settings. The step width
between two consecutive sweep points is constant and given by <Span>/(n - 1) where n is the specified
Number of Points (n > 1). The internal generator power can be set, if so desired, in the Power Bandwidth
Average submenu.
Lin. Frequency is the default sweep type. In a Cartesian diagram the measurement result is displayed as a
trace over a linear frequency scale (as known e.g. from spectrum analyzers). The following example
shows a Lin. Frequency sweep with a stimulus range between 300 kHz and 4 GHz, the forward
transmission parameter S
21
as measured quantity, and a dB Mag scaled y-axis.
