Rohde and Schwarz ZNH8 Handheld Vector Network Analyzer, Two-Port, 8 GHz

The Rohde & Schwarz ZNH8 is a two-port handheld Vector Network Analyzer delivering full S-parameter measurements from 30 kHz to 8 GHz. Built for field deployment, it combines benchtop-class performance with portable convenience for installation, maintenance, and RF system troubleshooting. The instrument features a 100 dB dynamic range, four independent receivers, and Type N female test ports rated to +23 dBm input. It supports one-port cable and antenna analysis—including distance-to-fault measurement—and complete two-port S-parameter characterization (S11, S21, S12, S22). Advanced UOSM calibration accommodates DUTs with mixed connector types. Trace noise remains below 0.003 dB RMS (magnitude) and 0.05° RMS (phase) across the operating band. Temperature stability is specified at 0.04 dB/K magnitude and 0.2°/K phase. Optional software keycodes unlock power measurement, pulse analysis, vector voltmeter functions, and variable DC bias (±2 V to +32 V) for active device testing. Power sensor integration extends measurement capability. The receiver step attenuator expands linear input power range, while measurement receiver linearity of 0.05 dB and power accuracy of 0.5 dB (measured, 10 MHz to 26.5 GHz) support precision characterization of passive and active components.
