Used vector network analyzers
A vector network analyzer (VNA) measures how components behave: filters, amplifiers, antennas, cables and connectors, in magnitude and phase. We stock used VNAs from Keysight / Agilent (PNA, ENA and older 87xx), Rohde & Schwarz and Anritsu, for RF and microwave work.
Buying a used network analyzer: what to check
- Frequency range and number of test ports
- Dynamic range and trace noise for your devices
- Options: time domain, frequency offset, extended power range
- A calibration kit and cables for your connector type
Every analyzer is inspected and function-tested, and each listing shows the actual unit, its ports, frequency range and installed options. A VNA is only as good as its calibration, so plan for a calibration kit that matches your connectors.
Port count, dynamic range and time-domain options are the usual deciding factors. If you need a matched calibration kit, test cables or a specific option set, ask us: we can often put a complete package together.
