R&S®SZM frequency multiplier

Precisely adjustable output levels when the electronically or mechanically controlled attenuator option is installed

R&S®SZM family of frequency multipliers combines easy handling and precise output levels in the frequency range from 50 GHz to 170 GHz. They can be used in diverse applications, e.g. in the automotive sector with distance radars, in astronomy with sophisticated telescopes and in radar interferometry for analyzing the earth’s surface.The family of frequency multipliers consists of the models R&S®SZM75 (from 50 GHz to 75 GHz), R&S®SZM90 (from 60 GHz to 90 GHz), R&S®SZM110 (from 75 GHz to 110 GHz), R&S®SZM140 (from 90 GHz to 140 GHz) and R&S®SZM170 (from 110 GHz to 170 GHz). Depending on which base unit is selected, high output power, an attenuator or an isolator can be installed as options. To simplify handling, all three options are integrated in the same housing as the frequency multiplier.To enable control of the R&S®SZM via USB, the R&S®SMAB-K554 option must be installed on the R&S®SMA100B signal generator. This combination operates as a single unit allowing users to directly enter the desired frequency and the target level at the R&S®SZM output on the R&S®SMA100B GUI.

Wide frequency range

• Frequency ranges from 50 GHz to 75 GHz, 60 GHz to 90 GHz, 75 GHz to 110 GHz, 90 GHz to 140 GHz and 110 GHz to 170 GHz
• Two models (e.g. R&S®SZM75 and R&S®SZM110) cover the wide frequency range from 50 GHz to 110 GHz

Versatile option concept

The frequency multiplier family R&S®SZM can be equipped with high power options or optional mechanically or electronically controlled attenuators. Depending on which base unit is selected, high output power, an attenuator or an isolator can be installed as options. To simplify handling, all three options are integrated in the same housing as the frequency multiplier. The optional Faraday isolator suppresses reflections and leads to a defined matching at the waveguide output. Finally, an optional test port adapter (TPA) can also be connected, which mechanically protects the R&S®SZM output.

Wide dynamic range

Optional mechanically or electronically controlled attenuator

The R&S®SZM can be conveniently controlled via USB with the R&S®SMA100B microwave signal generator. To enable control of the R&S®SZM via USB, the R&S®SMAB-K554 option must be installed on the R&S®SMA100B signal generator. This combination operates as a single unit allowing users to directly enter the wanted frequency and with a mechanically or electronically controlled attenuator also the target level at the R&S®SZM output on the R&S®SMA100B.

• Mechanically controlled attenuator option with a dynamic range of 40 dB (typ.)
• Electronically controlled attenuator with a dynamic range of 15 dB (typ.) if it is installed once, respectively 30 dB (typ.) if it is installed twice; if a high power option is not installed, the electronically controlled attenuator option can be installed twice

Easy handling

• Automatic detection and convenient control of the R&S®SZM by means of the R&S®SMA100B microwave signal generator via USB when the R&®SMAB-K554 option is installed on the R&S®SMA100B
• Easy setups with the one-box solution consisting of the R&S®SMA100B, the R&S®SZM plus an optional mechanically or electronically controlled attenuator
• Frequency setting on the R&S®SMA100B, taking the connected R&S®SZM into consideration
• Level setting on the R&S®SMA100B, taking the connected R&S®SZM into consideration (only for built-in attenuator)
• Automatic frequency response correction of the precalibrated R&S®SZM including attenuator by means of the R&S®SMA100B
• For frequency-, phase- and pulse-modulated signals
• Optional TPA (test port adapter) is a straight waveguide and simplifies connecting the DUT; it protects internal assemblies and their flange and can be easily replaced if damaged
• Optional Faraday isolator suppresses reflections and leads to a defined matching at the waveguide output

High signal quality

• Very low single sideband phase noise when the R&S®SMA100B high-end microwave signal generator is used as a source
• High output level accuracy when the mechanically or electronically controlled attenuator option is installed
• Excellent matching when the isolator option is installed
