2. On the R&S ZNA
a) prepare and run a "Pulse Profile" sweep
b) create a trace for the b-wave to be measured
c) set up and establish a VISA conncection to the target R&S VSE
d) start pushing data to the target R&S VSE
4.7.7 Millimeter-wave converter support
Option R&S ZNA-K8
Requires R&S ZNAxx-B16 (Direct generator/receiver access) or R&S ZNA-B26 (Direct
IF access).
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 LO Out, 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
