The pre-owned Agilent N5235B PNA-L couples wide-band 10 MHz-to-50 GHz coverage with a 122 dB receiver dynamic range and only 0.003 dB trace noise, revealing minute S-parameter changes without external boosters. A leveled +6 dBm source and full 2-port test set make it a cost-effective tool for microwave component production, on-wafer TRL/LRM calibration, and signal-integrity verification.

Buying refurbished slashes capital expense and lead-time; units ship ISO-17025-calibrated with current firmware, preserving Agilent reliability, SCPI/LAN automation, and future upgrade paths at a fraction of new-instrument cost.
