For a complete list of options, accessories, and extras refer to the product brochure or
to the "Options" section of the R&S
ZNA product pages on the Internet.
The following sections provide an introduction to the software and hardware options
described in this documentation. The use of external power meters, generators and
generic devices does not require any additional hardware or software options; it is
described at the end of the chapter.
4.7.1
Spectrum analyzer mode
Option R&S
ZNA-K1
Option R&S
ZNA-K1 enables spectrum analysis measurements on all receivers of the
R&S
ZNA (measurement receiver or reference receiver).
Up to 4 spectra can be measured in parallel, if the motherboard of the R&S
ZNA has a
product index 8 or higher (see the
). Motherboards with product index
<
8
do not support parallel spectrum measurements.
●
Before firmware version 2.40 only measurement receivers were available for spec-
trum measurements, and parallel spectrum measurements were not possible at all.
●
For more information on spectrum mode measurements and channel setups, see
the description of the
Chapter 5.2.11, "Spectrum tab"
ter 5.2.11.2, "Spectrum Setup dialog"
4.7.2
Time domain analysis
Option R&S
ZNA-K2
The network analyzer measures and displays complex S-parameters and other quanti-
ties as a function of the frequency. The measurement results can be filtered and math-
ematically transformed 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 lat-
ter, 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 side lobes due to the finite sweep range. Moreover, it is possible to elimi-
nate unwanted responses using a time gate and transform the gated result back into
the frequency domain.
For a detailed discussion of the time domain transformation including many examples,
refer to the application note 1EP83 which is available on the R&S internet at
