See the application note 1MA260 for information on the 802.11ad key parameters, and test setups for over-the-air (OTA) measurements.
Welcome to the R&S SZU
The R&S SZU from Rohde & Schwarz is an I/Q upconverter for use with the Rohde & Schwarz vector signal generator R&S SMW or R&S SMM.
The I/Q upconverter extends the frequency range for vector modulation to the 60 GHz frequency band. These frequencies are used in modern high-performance wireless communication standards, e.g. IEEE802.11 ad, or the application fields of 5G, supporting multiple radio frequency bands. Operating in the 60 GHz frequency band enables devices to communicate at multi-gigabit speed, with data transfer rates of several Gbit/s.
The R&S SZU I/Q 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 frequency options of the Rohde & Schwarz vector signal generator
Support of the R&S SMW / R&S SMM output level user correction
Fully calibrated at the waveguide port
Control via user interface of the R&S SMW / R&S SMM
Small size, easy usage, and operation in any position possible
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 / R&S SMM. It generates a vector-modulated signal by converting the baseband signal to the output frequency range of 58.32 GHz to 64.8 GHz (center frequency).
The USB host interface is the communication port of the R&S SZU to the vector signal generator. As external instrument, the R&S SZU is configured in the System Configuration dialog of the generator, and indicated by a symbol in the GUI. Once connected, the generator reads the calibration data of the R&S SZU, and adjusts the frequency and level values to the output values of this downstream instrument. Thus the R&S SMW / R&S SMM almost completely controls the R&S SZU. You only need to select single ended or differential mode for the baseband connection. It is recommended 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.
