Option Option Name Functionality
R&S ZVA-K6 True Differential Mode Generation of true differential and common mode stimuli at arbi-
trary reference planes in the test setup and measurement of the
mixed-mode S-parameters, wave quantities and ratios. Alterna-
tively: Defined coherence mode, provides several source signals
with defined phase and amplitude relation
R&S ZVA-K7 Measurements on Pulsed Signals Pulsed measurements in analogy to a time sweep (i.e. at constant
receiver frequency), but with a much higher sampling rate of 12.5/
ns.
R&S ZVA-K8 Converter Control Measurements at frequencies beyond the analyzer's operating
range
R&S ZVA-K9 Mixer Delay w/o LO Access Measurement of the absolute or relative group delay of a mixer.
R&S ZVA-K10 Long Distance Mixer Delay Mixer delay measurement with two different network analyzers,
one providing the source ports, the other the receive port.
R&S ZVA-K27 Internal Pulse Generators Provides two pulsed control signals to control pulsed measure-
ments.
R&S ZVAB-K30 Noise Figure Measurement Provides the noise figure of a DUT which operates in its linear
range.
R&S ZVA<frequency>-B16 Direct Generator/Receiver Access Give direct access to various RF input and output signals, e.g. to
insert external components into the signal path or develop custom
measurements; see Front Panel Jumpers.

Receiver Step Attenuators Control the received power, e.g. to avoid damage to the analyzer;
see Step Attenuators
R&S ZVB8-B21/22/23 Generator Step Attenuators Control the source power, e.g. to protect sensitive DUTs from
excess input levels; see Step Attenuators
The following sections provide a short introduction to the software options.
3.5.1 Time Domain (R&S ZVAB-K2)
The network analyzer measures and displays complex S-parameters and other quantities
as a function of the frequency. The measurement results can be filtered and mathemat-
ically transformed in order to obtain the time domain representation, which often gives a
clearer insight into the characteristics of the DUT.
Time domain transforms can be calculated in band pass or low pass mode. For the latter
the analyzer offers the impulse and step response as two alternative transformation
types. A wide selection of windows can be used to optimize the time domain response
and suppress sidelobes due to the finite sweep range. Moreover, it is possible to eliminate
unwanted responses by means of a time gate and transform the gated result back into
the frequency domain.
