Rohde & Schwarz introduces the new R&S ZNA high-end vector network analyzer, a powerful, universal test platform for characterizing active and passive components. 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 (typical) 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 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.

Unique hardware concept with four independent sources and two LOs

The R&S ZNA offers four internal, phase-coherent sources, eight parallel receivers and two internal local oscillators (LO). This simplifies the test setups for characterizing frequency-converting devices, amplifiers and complex T/R modules, requiring the device being tested to be connected only once. Users can perform vector corrected conversion loss, phase and group delay measurements in half the time required with the conventional approach and without the need for a reference mixer.

DUT-centric approach for best user experience

The R&S ZNA offers a unique approach, focused on the device under test (DUT), to simplify measurement configuration. The user first selects the type of DUT (e.g., a mixer or amplifier) and is then guided step-by-step through the configuration to the desired test setup.

This solution significantly facilitates and speeds test setups. Alternatively, users can take the conventional approach and configure measurements individually, which provides flexibility to master even the most challenging measurement tasks.

Modern touch interface replaces hard key panel

The R&S ZNA is the world's first purely touch-operated vector network analyzer, using a 12.1 in. touchscreen as the main display and a 7 in. touchscreen instead of a hard key panel. Together with the DUT-centric approach, the second touchscreen provides a seamless user experience.
