Agilent Keysight N5224B 43.5GHz 134dB Dynamic Range PNA Network Analyzer Vector Network Analyzer VNA

The refurbished Agilent N5224B PNA delivers vector-network accuracy from 10 MHz to 43.5 GHz with 134 dB receiver dynamic range and just 0.002 dB trace noise—sharp enough to reveal hair-thin S-parameter changes in high-gain or lossy fixtures. Fast 3.6 µs/point sweeps and a leveled +13 dBm source shorten compression, IMD and on-wafer TRL/LRM tasks, while SCPI/LAN control drops straight into existing automation.

Buying used slashes cap-ex and lead-time; units ship ISO-17025-calibrated with current firmware, preserving Agilent reliability and upgrade paths at a fraction of new-instrument cost.
