High-end VNA combines RF performance operating concept


ROHDE & SCHWARZ ZNA new generation of high-end vector network analyzers (VNA) provide improved RF performance and a hardware concept that simplifies measurement configuration. Unit’s measurement stability and trace noise enable users to perform demanding measurements on active and passive components and modules. Using a DUT-centric approach, the purely touch-operated VNA reduces configuration times to a minimum. Both models R&S ZNA26 (10MHz to 26.5GHz) and R&S ZNA43 (10MHz to 43.5GHz) deliver a dynamic range of 146dB (typ.) and a trace noise as low as 0.001dB at 1kHz IF bandwidth. These two features are essential for measurements on high-rejection filters. With its hardware concept, units 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 100dB power sweep range, a pulse generator and modulator per test port, versatile intermodulation measurement capabilities and spectrum analyzer functionality.
