The Rohde & Schwarz ZVH4 is a handheld cable and antenna analyzer that combines vector network analysis, spectrum analysis, and power measurement in a single portable instrument. Operating from 100 kHz to 3.6 GHz, it delivers 100 dB dynamic range and supports reflection measurement, cable fault location via distance-to-fault (DTF), and one-port cable loss analysis. The instrument expands to two-port VNA, spectrum analysis, directional power measurement, and pulse analysis through optional modules, making it adaptable to diverse field requirements.
