VNA 3 GHz Portable Vector Network Analyzer Rohde & Schwarz ZVL3

The pre-owned R&S ZVL3 unites network, spectrum and power analysis in a sub-7 kg chassis, giving R&D benches and production lines a single 9 kHz – 3 GHz workhorse.

A class-leading > 115 dB dynamic range and < 0.06 dB trace noise resolve deep filter notches and minute impedance mismatches, while 60 ms full-two-port sweeps keep throughput high. USB/LAN control (GPIB optional) supports automated test racks, and DC/battery operation lets the instrument double as a field-service VNA.

Delivered fully tested, freshly calibrated and firmware-current, this ZVL3 offers immediate deployment and significant savings over new hardware without compromising Rohde & Schwarz precision or long-term serviceability.
