High-End Vector Network Analyzers With Outstanding RF Performance


Rohde & Schwarz introduces the R&S ZNA, a new generation of high-end vector network analyzers with unique hardware concept that simplifies measurement configuration

Rohde & Schwarz presents the new R&S ZNA high-end vector network analyzer, a powerful, universal test platform for characterizing active and passive DUTs. The two models R&S ZNA26 (10 MHz to 26.5 GHz) and R&S ZNA43 (10 MHz to 43.5 GHz) offer an outstanding dynamic range of 146 dB (typ.) and a trace noise as low as 0.001 dB at 1 kHz IF bandwidth.


These two features are essential for measurements on high-rejection filters. With its unique hardware concept, the R&S ZNA can perform mixer measurements for RF and IF in parallel, delivering measurement speed twice as fast as with the conventional approach. Amplifier characterization becomes easy with a 100 dB power sweep range, a pulse generator and modulator per test port, versatile intermodulation measurement capabilities and spectrum analyzer functionality.

The R&S ZNA offers 4 internal, phase-coherent sources, 8 truly parallel receivers
and 2 internal local oscillators (LOs). This simplifies the test setups for characterizing
frequency-converting devices, amplifiers and even complex T/R modules, requiring the
DUT to be connected only once. Users can perform vector corrected conversion loss,
phase and group delay measurements in half of the time required with this
approach and without the need for a reference mixer.

The R&S ZNA also provides a unique approach which is focused on the DUT, to simplify measurement configuration. The user first selects the type of DUT (e.g. mixer or amplifier) and is then guided step by step through configuration to the desired test setup. This solution significantly speeds up and facilitates test setups.

Alternatively, the conventional approach of configuring measurements individually can be taken.

All of these solutions give high flexibility to master even the most challenging measurement tasks.
