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
