Pna L Network Analyzer Agilent Keysight N5234B 43.5 GHz 122 DB Dynamic Range Used Network Analyser

The pre-owned Agilent N5234B PNA-L delivers cost-effective vector-network analysis from 10 MHz to 43.5 GHz while providing 122 dB dynamic range and just 0.003 dB trace noise—enough to expose subtle S-parameter shifts in high-gain or lossy fixtures without external boosters.

A leveled +6 dBm source and 6 ms full-span sweep slash test times for filter, amplifier and on-wafer TRL/LRM calibrations. SCPI/LAN automation, upgradeable port options, and ISO-17025 calibration at shipment make this refurbished unit a drop-in replacement that preserves Agilent reliability and long-term serviceability at a fraction of new-instrument cost.
