The R&S®ZNA is Rohde & Schwarz flagship high-performance vector network analyzer for demanding R&D and compliance testing in RF, microwave and millimeter-wave industries. It covers frequency ranges from 10 MHz to 26.5 / 43.5 / 50 / 67 GHz, offered in 2-port and 4-port variants. The 4-port model integrates four independent phase-coherent internal signal sources.

Equipped with dual independent touchscreens and a unique DUT-centric fully touch-based operating concept, it features proprietary SMARTerCAL intelligent calibration algorithm, ultra-low trace noise, ultra-wide dynamic range and high output power. It delivers precise full-suite measurements including S-parameters, frequency conversion, pulsed signals and intermodulation distortion for passive components (filters, power dividers, couplers), active devices (power amplifiers, mixers, RF ICs), antennas, high-speed digital signal integrity and mmWave modules.
