R&S ZNA high-end vector network analyser

Rohde & Schwarz (R&S) has unveiled the ZNA high-end vector network analyser, a universal test platform for characterising 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 a 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 hardware concept, R&S says the ZNA can perform mixer measurements for RF and IF in parallel, delivering measurement speed twice as fast as with the conventional approach.

R&S adds that amplifier characterisation becomes easy with a 100 dB power sweep range, a pulse generator and modulator per test port, versatile intermodulation measurement capabilities and spectrum analyser functionality.

The R&S ZNA offers four internal, phase-coherent sources, eight truly parallel receivers and two internal local oscillators (LOs). This is to simplify the test setups for characterising 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 the conventional approach and without the need for a reference mixer, according to R&S.

The R&S ZNA offers what the company describes as a unique approach, 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 is designed to speed up and facilitate test setups. Alternatively, users can take the conventional approach and configure measurements individually.

R&S also adds that the ZNA is the world's first purely touch-operated vector network analyser using a 12.1" touchscreen as the main display and a 7" touchscreen instead of a hardkey panel.
