1 Safety and regulatory information
The product documentation helps you use the product safely and efficiently. Fol-
low the instructions provided here and in the following chapters.
Intended use
Millimeterwave converters R&S ZCxxx are designed to be used with Rohde &
Schwarz vector network analyzers R&S ZNA, R&S ZVA or R&S ZVT. They are
intended for the development, production and verification of electronic compo-
nents and devices in industrial, administrative, and laboratory environments. Only
use them for their designated purpose. Observe the operating conditions and per-
formance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential
dangers and gives instructions on how to prevent personal injury or damage
caused by dangerous situations. Safety information is provided as follows:
●Multilingual safety information is delivered with the converter power supply
R&S ZCPS and your Rohde & Schwarz vector network analyzer.
●Throughout the documentation, safety instructions are provided when you
need to take care during setup or operation.
1.1 Labels on the product
Labels on the casing inform about:
●Product and environment safety
●Identification of the product
Table 1-1: Labels regarding environment safety
Labeling in line with EN 50419 for disposal of electrical and electronic equipment after
the product has come to the end of its service life. For more information, see "Dispos-
ing electrical and electronic equipment" on page 36.

1.2 Warning messages in the documentation
A warning message points out a risk or danger that you need to be aware of. The
signal word indicates the severity of the safety hazard and how likely it will occur
if you do not follow the safety precautions.
NOTICE
Potential risks of damage. Could result in damage to the supported product or to
other property.

2 Key features
Intended use
Millimeterwave converters R&S ZCxxx extend the frequency range of a
R&S ZNA, R&S ZVA or R&S ZVT up to 1.1 THz.
They feature wide dynamic range and high output power. Except for R&S ZC90,
R&S ZC90E, R&S ZC110 and RPG ZC1100, the R&S ZCxxx converters have an
integrated variable mechanical attenuator.
Thanks to their unique USB interface, all relevant operating parameters of an indi-
vidual converter are automatically transferred to the base VNA without the need
to enter these parameters manually.
When used together with an R&S ZNA, the R&S ZCxxx converters can play to
their strength:
●They seamlessly integrate into the user interface of the base VNA.
●The R&S ZNA supports mixed configurations with different converter models
and native test ports without converter, which is particularly useful for fre-
quency-converting measurements.
●Automatic level control (ALC), in conjunction with the integrated output power
linearization ("leveling") functionality, allow the converters to provide precise
and stable source power over a wide power range.
Millimeterwave converters R&S ZCxxx supervise their own health state regarding
temperature, fan operation and DC supply.

The R&S ZC90E is equipped with an electronic attenuator and a corre-
sponding control interface.
●The R&S ZVA supports this control interface via hardware option
R&S ZVA-B8.
For a description of the corresponding connectors, their cabling and
operational aspects, see the Getting Started of the predecessor
R&S ZVA-Z90E. It can be downloaded from the manual page of the
R&S ZVA-Zxxx converter family (https://www.rohde-schwarz.com/
manual/zvaz/).
●R&S ZNA and R&S ZVT do not offer the external attenuator control
interface. With these analyzers, you can use the R&S ZC90E like a reg-
ular R&S ZC90, but with lower maximum output power and dynamic
range. See the data sheet of the R&S ZCxxx family for details.

3 Preparing for use
Here, you can find basic information about setting up the product for the first time.
3.1 Unpacking and checking
When you receive the converter, please take the following steps:
1. Unpack the converter and the other contents from the cardboard shipping box.
2. Retain the original packing material. Use it when transporting or shipping the
product later.
3. Using the delivery notes, check the equipment for completeness.
The shipment must include the following items:
● Converter
● DC supply cable
● USB cable
● IF cable EXT REF
● IF cable EXT MEAS
● External attenuator control cable (R&S ZC90E only)
● Plastic case with 8 flange screws 4-40 UNC 7.6 and 4 flange screws 4-40
UNC 9.24
● Plastic case with 8 precision dowels 1.566 mm ± 0.001 mm
● 3/32” hex ball driver
● Getting Started (this document)
4. Inspect the frequency converter, especially the test port adapter and the test
port flange surface, to make sure that no damages occurred during shipment.
If you observe any damages, immediately notify the shipping company and
keep the packing material.

3.2 Choosing the operating site
Specific operating conditions ensure proper operation and avoid damage to the
product and connected devices. For information on environmental conditions
such as ambient temperature and humidity, see the data sheet.
3.3 Setting up the converter
The frequency converter is designed for use under laboratory conditions on a flat
bench top or mounted on a wafer probe station. Four M8 threads are provided on
all long sides of the converter to allow for mounting the converter on a flat sur-
face. Some on-wafer measurement applications can require the converter to be
tilted to bring the test port closer to the chuck. In these cases, an additional bent
waveguide adapter can be necessary in front of the test port adapter to compen-
sate for the tilt angle.
Adjusting the feet of the converter
The instrument can be used with four feet attached to the respective bottom side
(depending on the orientation). When the DUT is mounted between two convert-
ers (see "Mounting a DUT" on page 14), use the feet for alignment of the com-
plete setup. A bubble level can help you to align each converter horizontally
before fitting the DUT.
3.4 Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●Use high-quality shielded RF cables.
●Always terminate open cable ends.
