Converter Control (Option R&S ZVA-K8, for R&S ZVA and R&S ZVT)
Measurements at frequencies beyond the network analyzer's operating range (mm-wave measurements)
are performed with an external test set (frequency converter) that multiplies the source frequency of the
analyzer up to the target mm-wave band and uses harmonic mixers to down-convert reference and test
receiver signals to an IF below 2 GHz. Rohde & Schwarz offers dedicated frequency converter types for
various mm-wave bands. The frequency converters R&S ZVA-Z110 and R&S ZVA-Z110E, for example,
extend the frequency range of R&S ZVA or R&S ZVT 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. For
the R&S ZVA-Z110(E) converter, the dimensions of the waveguides 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 converter
model.
Two different converter types are available:
Converters without electronic attenuators.
Even without electronic attenuator, some converter models allow a variation of the output power
by changing the input power of the source multiplier.
Converters with electronic attenuators (and an "E" in the type designation, e.g. R&S ZVA-Z110E).
For these models the output power can be adjusted either by the electronic attenuator alone or by
combining the attenuator with variable multiplier input power.
Required equipment and options
Frequency extension is available on R&S ZVA and R&S ZVT analyzers which are specified for
frequencies up to 20 GHz or above (e.g. ZVT 20, ZVA24, ZVA 40). The required firmware version
depends on the converter model. Refer to the release notes (What's new) or to the Getting Started guide
of your converter.
The following additional options and accessories are needed:
One or more frequency converters, depending on the test setup.
Option R&S ZVA-K8, Converter Control. Option R&S ZVA-K8 also comprises option ZVA-K4,
Arbitrary Generator and Receiver Frequencies.
Option R&S ZVA<frequency>-B16, Direct Generator/Receiver Access
For converters with electronic attenuator (e.g. R&S ZVA-Z110E): Option R&S ZVA-B8 to establish
the control connection between the NWA and the converter
A two-port transmission measurement requires two frequency converters plus a four-port network
analyzer or a two-port analyzer with an external generator. The external generator must provide
frequencies up to 20 GHz or above and sufficient signal power.
The external generator must be synchronized to the network analyzer using the 10 MHz reference
clock signal. It is not possible to use several external generators simultaneously.
