4 Welcome to the R&S SZU
The Rohde & Schwarz R&S SZU is an IQ upconverter designed for the 60 GHz
frequency band. These frequencies are used in modern high-performance wire-
less communication standards, e.g. IEEE802.11 ad. Operating in the 60 GHz fre-
quency band enables devices to communicate at multi-gigabit speed, with data
transfer rates of several Gbit/s.
Key features
The R&S SZU IQ Upconverter features:
●Compact broadband upconverter providing 57 GHz to 66 GHz frequency
●Power output of at least 5 dBm for over the air (OTA) RF measurements and
tests
●Adjustable output power in the range +5 dBm to -80 dBm, with integrated level
detector
●RF output signal at the waveguide port
●Support of common mountable test port adapters
●High-level stability and harmonic suppression
●Compatible to all R&S SMW frequency options
●Support of the R&S SMW output level user correction
●Fully calibrated at the waveguide port
●Control via user interface of the R&S SMW
●Small size, easy usage, and operation in any position possible
About the R&S SZU IQ Upconverter
The R&S SZU generates a vector-modulated signal by converting the baseband
signal to the output frequency range of 58.32 GHz to 64.8 GHz (center fre-
quency).
The R&S SZU receives the differential or single ended baseband signals (I/Q),
and an LO signal in the range of 1.944 GHz to 2.16 GHz from the R&S SMW.
The USB host interface is the communication port of the R&S SZU to the
R&S SMW. As external instrument, the R&S SZU is configured in the "System
Configuration" dialog of the R&S SMW, and indicated by a symbol in the GUI.
Once connected, the R&S SMW reads the calibration data of the R&S SZU, and

R&S®SZU100A

adjusts the frequency and level values to the output values of this downstream
instrument.
Thus the R&S SMW controls the R&S SZU almost entirely. You only need to
select single ended or differential mode for the baseband connection. It is recom-
mended that you work in differential mode due to better common mode noise
suppression over the single ended connection. When you work with two
R&S SZUs on one R&S SMW, you must work in single ended mode.
The setting parameters in the R&S SMW remain the same.

5 Preparing for Use
This section explains how to take an R&S SZU IQ Upconverter into operation. It
includes the controls and connectors of the R&S SZU, and provides all the infor-
mation necessary for connection.
For information on the equipment required for a basic test setup, see Chapter 7.1,
"System Requirements", on page 19.
5.1 Unpacking and Checking the R&S SZU
To remove the instrument from its packaging and to check the equipment for com-
pleteness, proceed as follows:
1. Unpack the R&S SZU and the other contents of the shipping container.
2. Check the equipment for completeness using the delivery list.
3. Remove the protective cap from the waveguide port at the front of the
R&S SZU. Inspect the instrument carefully, to make sure that it has no dam-
age from shipment.
If there is any damage, immediately contact the freight forwarder, who has
delivered the instrument.
Packaging material
It is recommended that you retain the original packaging material. If the
R&S SZU needs to be transported or shipped later, you can use the mate-
rial to prevent control elements and connectors from being damaged.
Equipment returned or sent in for repair must be packed in an appropriate
packaging, if the original packaging is no longer available.
Also use the packaging material for storage of the instrument and the
accessories.
