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, switch
matrices 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 Hardware tab). Motherboards with product index < 8
do not support parallel spectrum measurements.
To find out the motherboard product index of your R&S ZNA, go to the Hardware tab of
the "Info" dialog. Scroll to the "MB_MPM" row of the "Assemblies" table, and look at the
first number in the "Product Index" column.
For more information on spectrum mode measurements and channel setups, see the
description of the Spectrum tab and the Spectrum Setup dialog.
●
If a R&S ZNA50 or R&S ZNA67 is equipped with the Internal low noise preamplifier
option variant B312, or the Internal low power spur reduction amplifier option var-
iant B511, then option R&S ZNA-K1 is not available.
●
Before firmware version 2.40, only measurement receivers were available for spec-
trum measurements, and parallel spectrum measurements were not possible at all.
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-
