Rohde & Schwarz offers dedicated frequency converter types for various mm-wave
bands. The frequency converter R&S
ZC110, for example, extend the frequency range
of R&S
ZNA network analyzers to a W-band range between 75 GHz and 110 GHz. The
test ports of the frequency converters and the connecting elements are rectangular
waveguides, whose dimensions are according to EIA WR-10, equivalent to RCSR
WG-27.
Refer to the Getting Started guide and the specifications supplied with your converter
for detailed information about the frequency range and the waveguide type of your con-
verter model.
Controlling the electronic attenuator of legacy converters R&S
ZVA-Z90E and
R&S
ZVA-Z110E is
not
supported.
R&S Converter Leveling Tool
For linearization of the converter output power over a wide range of power levels and
frequencies, the R&S Converter Leveling Tool can be used. It conducts a reference
receiver calibration and records the converter's power transfer function. For ease of
operation, all these steps are conducted automatically and can be triggered by just one
mouse-click. From the calibration measurements a data set is derived which compen-
sates for the converter's nonlinearities.
The R&S Converter Leveling Tool facilitates converter output power sweeps of up to 70
dB and thus is particularly beneficial for intercept or compression point measurements.
The software tool and a detailed Getting Started manual can be downloaded from the
R&S website (see
