the corresponding a-wave. See section "Power Calibration for Converters without
Electronic Attenuators" in the R&S ZVA/ZVT online help for details.
Accepting some limitations w.r.t. temperature stability, the R&S ZVA Frequency
Converter Leveling Tool can be applied for the linearization of output power in the
frequency range of interest. For further details, refer to the R&S ZVA/ZVT online
help (description of "RF In Power (and Electronic Attenuator) with Data Set"
option), and the Getting Started document of R&S ZVA Frequency Converter Lev-
eling Tool.
For precise S-parameter measurements, a system error correction is recommen-
ded. System error correction requires a calibration kit for the waveguide band of
the specific R&S ZCxxx converter. Activating the frequency converter mode for a
R&S ZCxxx does not imply automatic installation of a suitable R&S waveguide kit
in the analyzer firmware, as it is the case for the R&S ZVA-Zxxx converters. To
have at least one cal kit defined when getting started with a R&S ZCxxx con-
verter, the R&S ZVA-WRxx kits have been pre-installed in the R&S ZVA/ZVT firm-
ware. They are assigned, however, to WM-xxxx connectors, as far as the WRxx
waveguide bands are identical to the newer WM-xxxx bands.
The standards in the calibration kits allow for OSM, TOSM, UOSM, TOM, TRM
and TRL calibrations. Refer to the documentation of the calibration kit or the
R&S ZVA/ZVT online help for details.
A.2.6 Measurement
After power calibration and system error correction, the mm-wave measurement
can be performed like any other network analyzer measurement. The port config-
uration dialog ("Channel > Mode > Port Configuration") shows the frequency and
power sweep ranges of all implied signals, including RF IN, LO IN and IF output.
All measured quantities (S-parameters, wave quantities, ratios etc.) are available.
Flat power and power sweep are only available if a power correction data set has
been previously taken with the R&S Converter Leveling Tool.
The R&S Converter Leveling Tool is a separate software that can be instal-
led on the R&S ZVA/ZVT or on a separate PC. Installer and documentation
are available on the R&S ZVA software page https://www.rohde-
schwarz.com/software/zva/.
