Rohde & Schwarz ZVT8 300.00 KHz – 8.00 GHz Vector S-ParaMeter Network Analyzer

The Rohde & Schwarz ZVT8 is a multiport vector network analyzer operating from 300 kHz to 8 GHz, configurable with 2 to 8 test ports in a single unit. Each port includes a dedicated reflectometer with independent generators for port pairs, enabling simultaneous measurement of all signal paths. This architecture delivers eight-port measurements in 8 ms and captures 201 points in 5 ms, making it ideal for production testing, quality assurance, and R&D of complex multiport devices.

The instrument supports manual lab operation and automated integration via IEC/IEEE bus or LAN interfaces.
