Measurements at frequencies beyond the analyzer's operating range (mm-wave mea-
surements) are achieved by combining a frequency-converting measurement with an
external test set (standalone frequency converter, or combined with a diplexer in case
of R&S ZNA67EXT). The frequency converters use frequency multipliers to transform
the RF source signal from one of the network analyzer ports into a high-frequency
stimulus signal. A dual directional coupler separates the reference and measurement
channels from the waveguide test port. A local oscillator (LO) signal is used for down-
converting the reference and measurement channels. The LO signal can be provided
by the optional LO Out, or by an analyzer or external generator port. The down-conver-
ted reference and measurement signals are fed to the respective B16 or B26 ports.

On a R&S
ZNA67EXT, this option is preinstalled.
Rohde & Schwarz offers dedicated frequency converter types for various mm-wave
bands. The frequency converter R&S ZC110, for example, extends 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 rec-
tangular 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.
