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 (frequency converter). The frequency converters use frequency multi-
pliers 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
, or by an analyzer or external generator port.
The down-converted reference and measurement signals are fed to the respective B16
or B26 ports.

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
