Rohde & Schwarz ZVA50 Vector Network Analyzer VNA 50 GHz High Performance

The pre-owned R&S ZVA50 delivers metrology-grade S-parameter measurements from 10 MHz to 50 GHz, pairing a ≥ 120 dB dynamic range with sub-0.003 dB trace noise to resolve deep filter notches and minute impedance mismatches.

Fast ~3 ms sweeps over 401 points accelerate tuner characterization and production throughput, while wide IF-bandwidth selections and a 90 dB power-sweep span accommodate both ultra-low-noise devices and high-power components. Touchscreen operation, LAN / GPIB automation and comprehensive calibration wizards streamline workflow, and field-upgradeable options—such as frequency-offset mode, time-domain analysis and automatic fixture removal—future-proof the platform.

Supplied fully tested, freshly calibrated and loaded with current firmware, each unit ships from stock, delivering Rohde & Schwarz precision at a fraction of new-instrument cost.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
